• Though the FRENIC-Ace is manufactured under strict quality control, install safety devices for applications where serious accidents or property damages are foreseen in relation to the failure of it
An accident could occur
Installation
• Install the inverter on a base made of metal or other non-flammable material
Otherwise, a fire could occur
• Do not place flammable object nearby
Doing so could cause fire
• Inverters FRN0085E2■-4or above, whose protective structure is IP00, involve a possibility that a human body may touch the live conductors of the main circuit terminal block Inverters to which an optional DC reactor is connected also involve the same Install such inverters in an inaccessible place
Otherwise, electric shock or injuries could occur
• Do not support the inverter by its front cover during transportation
Doing so could cause a drop of the inverter and injuries
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink
• When changing the positions of the top and bottom mounting bases for external cooling, use only the specified screws
Otherwise, a fire or an accident might result
• Do not install or operate an inverter that is damaged or lacking parts
Doing so could cause fire, an accident or injuries
Trang 16residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of each pair of power lines to inverters Use the recommended devices within the recommended current capacity
• Use wires in the specified size
• Tighten terminals with specified torque
Otherwise, a fire could occur
• When there is more than one combination of an inverter and motor, do not use a multicore cable for the purpose of handling their wirings together
• Do not connect a surge killer to the inverter's output (secondary) circuit
Doing so could cause a fire
• Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds
500 kVA and is 10 times or more the inverter rated capacity
Otherwise, a fire could occur
• Ground the inverter in compliance with the national or local electric code
• Be sure to ground the inverter's grounding terminals G
Otherwise, an electric shock or a fire could occur
• Qualified electricians should carry out wiring
• Be sure to perform wiring after turning the power OFF
Otherwise, an electric shock could occur
• Be sure to perform wiring after installing the inverter unit
Otherwise, an electric shock or injuries could occur
• Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage of the AC power supply to which the product is to be connected
Otherwise, a fire or an accident could occur
• Do not connect the power supply wires to output terminals (U, V, and W)
• When connecting a DC braking resistor (DBR), never connect it to terminals other than terminals P(+) and
DB
Doing so could cause fire or an accident
• In general, sheaths of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced insulation is not applied) Therefore, if a control signal wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath might break down, which would expose the signal wire to a high voltage of the main circuit Make sure that the control signal wires will not come into contact with live conductors of the main circuit
Doing so could cause an accident or an electric shock
• Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and wait at least five minutes for inverters FRN0115E2■-2 / FRN0072E2■-4 / FRN0011E2■-7 or below,
or at least ten minutes for inverters FRN0085E2■-4 or above Make sure that the LED monitor and
charging lamp are turned OFF Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below)
Otherwise, an electric shock could occur
Trang 17• Be sure to mount the front cover before turning the power ON Do not remove the cover when the inverter power is ON
Otherwise, an electric shock could occur
• Do not operate switches with wet hands
Doing so could cause electric shock
• If the auto-reset function has been selected, the inverter may automatically restart and drive the motor depending on the cause of tripping Design the machinery or equipment so that human safety is ensured at the time of restarting
Otherwise, an accident could occur
• If the stall prevention function (current limiter), automatic deceleration (anti-regenerative control), or overload prevention control has been selected, the inverter may operate with acceleration/deceleration or frequency different from the commanded ones Design the machine so that safety is ensured even in such cases
• The key on the keypad is effective only when the keypad operation is enabled with function code F02 (=
0, 2 or 3) When the keypad operation is disabled, prepare an emergency stop switch separately for safe operations
Switching the run command source from keypad (local) to external equipment (remote) by turning ON the
"Enable communications link" command LE disables the key To enable the key for an emergency stop, select the key priority with function code H96 (= 1 or 3)
• If any of the protective functions have been activated, first remove the cause Then, after checking that the all run commands are set to OFF, release the alarm If the alarm is released while any run commands are set to
ON, the inverter may supply the power to the motor, running the motor
Otherwise, an accident could occur
• If you enable the "Restart mode after momentary power failure" (Function code F14 = 3 to 5), then the inverter automatically restarts running the motor when the power is recovered
Design the machinery or equipment so that human safety is ensured after restarting
• If the user configures the function codes wrongly without completely understanding this User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine
• Starting auto-tuning involves motor rotation Sufficiently check that motor rotation brings no danger beforehand
An accident or injuries could occur
• Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input terminals L1/R, L2/S, L3/T, L1/L and L2/N, voltage may be output to inverter output terminals U, V, and W
• Even if the motor is stopped due to DC braking or preliminary excitation, voltage is output to inverter output terminals U, V, and W
An electric shock may occur
• The inverter can easily accept high-speed operation When changing the speed setting, carefully check the specifications of motors or equipment beforehand
Otherwise, injuries could occur
• Do not touch the heat sink and braking resistor because they become very hot
Doing so could cause burns
• The DC brake function of the inverter does not provide any holding mechanism
• Ensure safety before modifying the function code settings
Run commands (e.g., "Run forward" FWD), stop commands (e.g., "Coast to a stop" BX), and frequency
change commands can be assigned to digital input terminals Depending upon the assignment states of those terminals, modifying the function code setting may cause a sudden motor start or an abrupt change in speed
• When the inverter is controlled with the digital input signals, switching run or frequency command sources
with the related terminal commands (e.g., SS1, SS2, SS4, SS8, Hz2/Hz1, Hz/PID, IVS, and LE) may cause a
sudden motor start or an abrupt change in speed
• Ensure safety before modifying customizable logic related function code settings (U codes and related
function codes) or turning ON the "Cancel customizable logic" terminal command CLC Depending upon the
settings, such modification or cancellation of the customizable logic may change the operation sequence to cause a sudden motor start or an unexpected motor operation
An accident or injuries could occur
Trang 18• Always carry out the daily and periodic inspections described in the instruction/user's manual Use of the inverter for long periods of time without carrying out regular inspections could result in malfunction or damage, and an accident or fire could occur
• It is recommended that periodic inspections be carryout every one to two years, however, they should be carried out more frequently depending on the usage conditions
• It is recommended that parts for periodic replacement be replaced in accordance with the standard replacement frequency indicated in the user's manual Use of the product for long periods of time without replacement could result in malfunction or damage, and an accident or fire could occur
• Contact outputs [30A/B/C] use relays, and may remain ON, OFF, or undetermined when their lifetime is reached In the interests of safety, equip the inverter with an external protective function
Otherwise, an accident or fire could occur
• Maintenance, inspection, and parts replacement should be made only by qualified persons
• Take off the watch, rings and other metallic objects before starting work
• Use insulated tools
Otherwise, an electric shock or injuries could occur
• Never modify the inverter
Doing so could cause an electric shock or injuries
Disposal
• Treat the inverter as an industrial waste when disposing of it
Otherwise injuries could occur

Trang 251.3 Precautions for Using Inverters
This section provides precautions in introducing inverters, e.g precautions for installation environment, power
supply lines, wiring, and connection to peripheral equipment Be sure to observe those precautions
1.3.1 Usage environment
Install the inverter in an environment that satisfies the requirements listed in Table 1.3-1
Table 1.3-1 Usage Environment Item Specifications Site location Indoors
Ambient temperature Standard(Open Type)
-10 to +50C (14 to 122F) (HHD/HND spec.) (Note 1) -10 to +40C (14 to 104F) (HD/ND spec.)

gases, oil mist, vapor or water drops
Pollution degree 2 (IEC60664-1) (Note 2)
The atmosphere can contain a small amount of salt (0.01 mg/cm2 or less per year)
The inverter must not be subjected to sudden changes in temperature that will cause condensation to form
Altitude 1,000 m (3,300 ft) max (Note 3)
Atmospheric pressure 86 to 106 kPa
Vibration FRN0115E2■-2 or below
FRN0203E2■-4 or below FRN0011E2■-7 or below
2 m/s2 20 to less than 55 Hz 1 m/s2 55 to less than 200 Hz
1 m/s2 55 to less than 200 Hz
(Note 1) When inverters are mounted side-by-side without any clearance between them (FRN0011E2■-7 /
FRN0115E2■-2 / FRN0072E2■-4 or below), the ambient temperature should be within the range
from -10 to +40C
(Note 2) Do not install the inverter in an environment where it may be exposed to lint, cotton waste or moist dust or
dirt which will clog the heat sink of the inverter If the inverter is to be used in such an environment, install
it in a dustproof panel of your system
(Note 3) If you use the inverter in an altitude above 1,000 m (3,300 ft), you should apply an output current derating
factor as listed in Table 1.3-2
Table 1.3-2 Output Current Derating Factor in Relation to Altitude
Trang 26Any of the following measures may be necessary
- Mount the inverter in a sealed panel with IP6X or air-purge mechanism
- Place the panel in a room free from influence of the gases
Paper manufacturing, sewage disposal, sludge treatment, tire
manufacturing, gypsum manufacturing, metal processing, and a particular process in textile factories
Any of the following measures may be necessary
- Mount the inverter in a sealed panel
- Place the panel in a room free from influence of the conductive dust
Wiredrawing machines, metal processing, extruding machines, printing presses, combustors, and industrial waste treatment
A lot of fibrous or
paper dust
Fibrous or paper dust accumulated on the heat sink lowers the cooling effect
Entry of dust into the inverter causes the electronic circuitry
in panel engineering design
- Employ external cooling when mounting the inverter in a panel for easy maintenance and perform periodical maintenance
Textile manufacturing and paper manufacturing
High humidity or dew
condensation
In an environment where a humidifier is used or where the air conditioner is not equipped with a dehumidifier, high humidity or dew condensation results, which causes a short-circuiting or malfunction
of electronic circuitry inside the inverter
- Put a heating module such as a space heater in the panel
Outdoor installation Film manufacturing line, pumps and food processing.
or blasting at a construction site, the inverter structure gets damaged
- Insert shock-absorbing materials between the mounting base of the inverter and the panel for safe mounting
Installation of an inverter panel on a carrier or self-propelled machine Ventilating fan at a construction site or a press machine
Fumigation for export
packaging
Halogen compounds such as methyl bromide used in fumigation corrodes some parts inside the inverter
- When exporting an inverter built in
a panel or equipment, pack them in
a previously fumigated wooden crate
- When packing an inverter alone for export, use a laminated veneer lumber (LVL)
Exporting
Trang 27The storage environment in which the inverter should be stored after purchase differs from the usage environment
Store the inverter in an environment that satisfies the requirements listed below
Table 1.3-3 Storage and Transport EnvironmentsItem Specifications
Storage temperature *1 During transport: -25 to +70C (-13 to +158F)
Places not subjected to abrupt temperature changes or condensation
or freezing
During storage: -25 to +65C (-13 to +153F) Relative humidity 5 to 95% RH *2
Atmosphere The inverter must not be exposed to dust, direct sunlight, corrosive or flammable gases,
oil mist, vapor, water drops or vibration The atmosphere must contain only a low level of salt (0.01 mg/cm2 or less per year)
Atmospheric pressure 86 to 106 kPa (during storage)
70 to 106 kPa (during transportation)
*1 Assuming comparatively short time storage, e.g., during transportation or the like
*2 Even if the humidity is within the specified requirements, avoid such places where the inverter will be
subjected to sudden changes in temperature that will cause condensation or freezing
Precautions for temporary storage
(1) Do not leave the inverter directly on the floor
(2) If the environment does not satisfy the specified requirements listed in Table 1.3-3, wrap the inverter in an
airtight vinyl sheet or the like for storage
(3) If the inverter is to be stored in a high-humidity environment, put a drying agent (such as silica gel) in the
airtight package described in (2) above
[ 2 ] Long-term storage
The long-term storage method of the inverter varies largely according to the environment of the storage site
General storage methods are described below
(1) The storage site must satisfy the requirements specified for temporary storage
However, for storage exceeding three months, the surrounding temperature range should be within the range
from -10 to +30°C (14 to 86°F) This is to prevent electrolytic capacitors in the inverter from deterioration
(2) The package must be airtight to protect the inverter from moisture Add a drying agent inside the package to
maintain the relative humidity inside the package within 70%
(3) If the inverter has been installed to the equipment or panel at construction sites where it may be subjected to
humidity, dust or dirt, then temporarily remove the inverter and store it in the environment specified in Table
1.3-3
Precautions for storage over 1 year
If the inverter has not been powered on for a long time, the property of the electrolytic capacitors may deteriorate
Power the inverters on once a year and keep the inverters powering on for 30 to 60 minutes Do not connect the
inverters to the load circuit (secondary side) or run the inverter
Trang 28operation
An overvoltage trip that occurs when the inverter is stopped or running with a light load is assumed to be due to surge current generated by open/close of phase-advancing capacitors in the power system An optional DC/AC reactor (DCR/ACR) is recommended as a measure to be taken at the inverter side
Inverter input current to an inverter contains harmonic components that may affect other motors and phase-advancing capacitors on the same power supply line If the harmonic components cause any problems, connect a DCR/ACR to the inverter In some cases, it is necessary to insert a reactor in series with the phase-advancing capacitors
Use a DC reactor (DCR) when the capacity of the power supply transformer is 500 kVA or more and is 10 times or more the inverter rated capacity or when there are thyristor-driven loads If no DCR is used, the percentage-reactance of the power supply decreases, and harmonic components and their peak levels increase These factors may break rectifiers or capacitors in the converter section of the inverter, or decrease the capacitance of the capacitors
If the input voltage unbalance rate is between 2% and 3%, use an optional AC reactor (ACR)

=(%)unbalance
(for suppressing harmonics)
To correct the inverter input power factor (to suppress harmonics), use a DCR Using a DCR increases the reactance of inverter’s power source so as to decrease harmonic components on the power source lines and correct the power factor of the inverter
DCR models Input power factor Remarks
DCR2/4-/A/B Approx 90% to 95% The last letter identifies the capacitance
DCR2/4-C Approx 86% to 90% Exclusively designed when applying with motors with a rated capacity of 37 kW or above
• Select a DCR matching not the inverter capacity but the rated capacity of the applied motor Applicable reactors differ depending upon the selected ND, HD, HND or HHD mode even on the same type of inverters
• For applied motors of 75 kW or above, be sure to connect a DCR to the inverter
Using a PWM converter (High power-factor, regenerative PWM converter, RHC series) corrects the inverter power factor up to nearly “1.”
When combining an inverter with a PWM converter, disable the main power down detection by setting the function code H72 to “0” (default) If the main power down detection is enabled (H72 = 1, factory default), the inverter interprets the main power as being shut down, ignoring an entry of a run command
Trang 29[ 5 ] Molded case circuit breaker (MCCB) / residual-current-operated protective device
(RCD) / earth leakage circuit breaker (ELCB)
Install a recommended MCCB or RCD/ELCB (with overcurrent protection) in the primary circuit of the inverter to
protect the wiring Since using an MCCB or RCD/ELCB with a lager capacity than recommended ones breaks the
protective coordination of the power supply system, be sure to select recommended ones Also select ones with
short-circuit breaking capacity suitable for the power source impedance
If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is installed in the
upstream power supply line in order to avoid the entire power supply system's shutdown undesirable to factory
operation, install a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)
individually to inverters to break the individual inverter power supply lines only
Otherwise, a fire could occur
Avoid frequent ON/OFF operation of the magnetic contactor (MC) in the input circuit; otherwise, the inverter failure
may result If frequent start/stop of the motor is required, use FWD/REV terminal signals or the / keys on
the inverter's keypad
The frequency of the MC's ON/OFF should not be more than once per 30 minutes To assure 10-year or longer
service life of the inverter, it should not be more than once per hour
• From the system's safety point of view, it is recommended to employ such a sequence that shuts down
the magnetic contactor (MC) in the inverter input circuit with an alarm output signal ALM issued on
inverter's programmable output terminals The sequence minimizes the secondary damage even if the
inverter breaks
When the sequence is employed, connecting the MC's primary power line to the inverter's auxiliary
control power input makes it possible to monitor the inverter's alarm status on the keypad
• The breakdown of a braking unit or misconnection of an external braking resistor may cause damage
of the inverter's internal parts (e.g., charging resistor) To avoid such a breakdown linkage, introduce an
MC and configure a sequence that shuts down the MC if a DC link voltage establishment signal is not
issued within three seconds after the MC is switched on
For the braking transistor built-in type of inverters, assign a transistor error output signal DBAL on
inverter's programmable output terminals to switch off the MC in the inverter input circuit
If a magnetic contactor (MC) is inserted in the inverter's output (secondary) circuit for switching the motor to a
commercial power or for any other purposes, it should be switched on and off when both the inverter and motor are
completely stopped This prevents the contact point from getting damaged due to a switching arc of the MC The
MC should not be equipped with any main circuit surge killer
Applying a commercial power to the inverter's output circuit breaks the inverter To avoid it, interlock the MC on the
motor's commercial power line with the one in the inverter output circuit so that they are not switched ON at the
same time
Do not install any surge absorber or surge killer in the inverter's output (secondary) lines
Trang 30- Connect a noise filter to the inverter power wires
- Isolate the power system of the other devices from that of the inverter with an insulated transformer
- Decrease the inverter's carrier frequency (F26) See Note below
(2) If induction or radiated noise generated from the inverter affects other devices:
- Isolate the main circuit wires from the control circuit wires and other devices wires
- Put the main circuit wires through a metal conduit pipe, and connect the pipe to the ground near the
inverter
- Install the inverter into the metal panel and connect the whole panel to the ground
- Connect a noise filter to the inverter's power wires
- Decrease the inverter's carrier frequency (F26) See Note below
(3) When implementing measures against noise generated from peripheral equipment:
- For inverter's control signal wires, use twisted or shielded-twisted wires When using shielded-twisted
wires, connect the shield of the shielded wires to the common terminals of the control circuit
- Connect a surge absorber in parallel with magnetic contactor's coils or other solenoids (if any)
Note: Running a permanent magnet synchronous motor (PMSM) at a low carrier frequency may heat the
permanent magnet due to the output current harmonics, resulting in demagnetization When decreasing the
carrier frequency setting, be sure to check the allowable carrier frequency of the motor
1.3.5 Leakage current
A high frequency current component generated by insulated gate bipolar transistors (IGBTs) switching on/off inside
the inverter produces leakage current through stray capacitance of inverter input and output wires or a motor If any
of the problems listed below occurs, take an appropriate measure against them
Problem Measures
An earth leakage circuit
breaker* that is connected to
the input (primary) side has
tripped
* With overcurrent protection
1) Decrease the carrier frequency See Note below
2) Make the wires between the inverter and motor as short as possible
3) Use an earth leakage circuit breaker with lower sensitivity than the one currently used
4) Use an earth leakage circuit breaker that features measures against the high frequency current component (Fuji SG and EG series)
An external thermal relay was
falsely activated
1) Decrease the carrier frequency See Note below
2) Increase the current setting of the thermal relay
3) Use the electronic thermal overload protection built in the inverter, instead of the external thermal relay
Note: Running a permanent magnet synchronous motor (PMSM) at a low carrier frequency may heat the
permanent magnet due to the output current harmonics, resulting in demagnetization When decreasing the
carrier frequency setting, be sure to check the allowable carrier frequency of the motor
1.3.6 Precautions in driving a permanent magnet synchronous motor (PMSM)
When using a PMSM, note the following
• When using a PMSM other than the Fuji standard synchronous motor (GNB2), consult your Fuji Electric
representative

(3) Surrounding Space
Secure the space shown in Figure 2.1-1 and Table 2.1-1 When
enclosing FRENIC-Ace in cabinets, be sure to provide adequate
ventilation to the cabinet, as the surrounding temperature may rise Do
not contain it in small enclosures with low heat dissipation capacity
When installing 2 or more units in the same equipment or cabinet,
generally mount them to the side of each other, not above each other
When the inverters are mounted above each other, attach partitioning
boards to prevent that the heat dissipated from the lower inverter affects
the upper inverter
For types FRN0072E2-4, FRN0115E2-2, FRN0011E2-7 or
below and for ambient temperature below 40°C only, the units can be
installed side by side without any spacing between them (30°C or lower

(Note 16)
Trang 37(Note 1) Install recommended circuit breakers (MCCB) or residual-current-operated protective device (RCD)/
earth leakage breakers (ELCB) (with overcurrent protective function) on the inputs of each inverter
(primary side) for wiring protection Do not use breakers which exceed the recommended rated current
(Note 2) Install recommended magnetic contactors (MC) as necessary on each inverter as these will be used to
disconnect the inverter from the power supply separately from the MCCB or RCD / the ELCB
Additionally, when installing coils such as MC or solenoid close to the inverter, connect surge absorbers
in parallel
(Note 3) When it is desired to retain the alarm signal for the activation of the protective function even inverter
main power supply is shut off, or when it is desired continuous display of the keypad, connect this
terminal to the power supply The inverter can be operated without connecting power to this terminal
(applicable for types FRN0059E2■-4/ FRN00088E2■-2 or above)
(Note 4) The terminal does not need to be connected Use this terminal when operating in combination with a
high power factor regenerative PWM converter (RHC series) Applicable for types FRN0203E2■-4 or
above)
(Note 5) Remove the shorting bar between the inverter main circuit terminals P1-P(+) before connecting the
direct current reactor (DCR) (option)
It must be connected in the following cases:
ND mode: Types FRN0139 E2■-4 or above, HD/ HND mode: Types FRN0168E2■-4 or above, HHD
mode: Types FRN0203E2■-4 or above
Use the direct current reactor (option) when the power supply transformer capacity is above 500 kVA
and the transformer capacity is over 10 times the rated capacity of the inverter, or when “thyristor load
exists” in the same power system
(Note 6) Types FRN0011E2■-7/FRN0115E2■-2/ FRN0072E2■-4 or below have built-in braking transistors,
allowing direct connection of braking resistors between P(+)-DB
(Note 7) When connecting braking resistors to types FRN0085E2■-4 or above, always add the braking unit
(option) Connect the braking unit (option) between P(+)-N(-) Auxiliary terminals [1] and [2] have polarity
Please connect as shown in the diagram
(Note 8) This terminal is used for grounding the motor Grounding the motor using this terminal is recommended
in order to suppress inverter noise
(Note 9) Use twisted lines or shielded lines for the control signals
Generally, the shielded line requires grounding, but when the effect of externally induced noise is large,
connecting to [CM] may suppress the effect of noise Separate the line from the main circuit wiring and
do not enclose in the same duct (Separation distance of over 10 cm is recommended.) When crossing
the main circuit wiring, make the intersection perpendicular
(Note 10) The various functions listed for terminals[X1] to [X5](digital inputs), terminals [Y1] to [Y2](transistor
output), and terminal [FM] (monitor output) show the functions assigned as factory default
(Note 11) These are connectors for switching the main circuit For details, refer to “2.2.7 Switching connector
(types FRN0203E2■-4 or above)”
(Note 12) The slide switches on the control printed circuit board define the settings for the inverter operation For
details, refer to “2.2.8 Operating slide switches”
(Note 13) Make the circuit breakers (MCCB) or the magnetic contactors (MC) trip by the thermal relay auxiliary
contacts (manual recovery)
(Note 14) Shorting bars are connected between the safety function terminals [EN1], [EN2], and [PLC] as factory
default Remove the shorting bars when using this function
(Note 15) and are separated and insulated
(Note 16) Charge lamp does not exist in the inverters FRN0069E2■-2/FRN0044E2■-4/FRN0011E2■-7 or

1) Loosen the screws of the front cover Hold both sides of the front cover with the hands and slide it upward to
Trang 40L1/L, L2N(Single-phase) (The inverter will be damaged when power is applied if the power lines are connected to the wrong terminals.)
(3) Always route the ground line to prevent accidents such as electric shock and fire and to reduce noise (4) For the lines connecting to the main circuit terminals, use crimped terminals with insulating sleeves or use crimped terminals in conjunction with insulating sleeves for high connection reliability
(5) Separate the routing of the lines connected to the main circuit input side terminals (primary side) and the output side terminals (secondary side) and the lines connected to the control circuit terminals
The control circuit terminal lines should be routed as far as possible from the main circuit routing Malfunction may occur due to noise
(6) To prevent direct contact with the main circuit live sections (such as the main circuit terminal block), route the control circuit wiring inside the inverter as bundles using cable ties
(7) After removing a main circuit terminal screw, always restore the terminal screw in position and tighten even if lines are not connected
(8) The wiring guide is used to separately route the main circuit wiring and the control circuit wiring The main circuit wiring and the control circuit wiring can be separated Exercise caution for the order of wiring
