Trang 7Off position stop method
In case with the uninterrupted power system, it is
recommended to stop at the OFF position set by tripping
mechanism for the stable power Instantaneous transfer without
stop can be also performed by operating signal
And also, instantaneous transfer can be performed by operating
signal
One-Coil Application
One-coil is employed for the transfer to normal power source
and emergency power source
Compact & Lightweight Design
Compact & lightweight design makes the minimized mounting
space and convenient installation
Excellent Breaking Capacity
Designed for suffciently large chamber to extinguish the arc
when transferred Arc-extinguishing area is designed for
convenient inspection and maintenance
Protection against the remaining power source
Time delay to transfer is available so that the remaining power
can not be induced to the main power to protect the load
Construction for Safety
For safe operation, molded construction is employed on
breaking parts And also, latching indicator is prepared to
indicate the operating condition

Control Order
It is recommended to give more than 0.5 sec for operation,
though transfer time is completed within 0.3 sec
Interlock
Interlocking is required for control circuit so that control order
should not suppy to both A power source side and B power
source side simultaneously For TN type ATS, Sequence setting
is required so that closing or tripping order should not supply in
the same direction
Control Circuit
ATS is designed so that operation current should be off by
internal switch after completion of operation If operation current
is off with auxiliary switch of the unit, it may cause a malfunction

Standard Operating Conditions
Ambient Temperature: -5 C~+40 C(but, the average temperature for 24 hours shall be lower than +35 C)Altitude: Below 2000m
Environmental conditions
Relative humidity shall be less than 85% at max temp +40 C, less than 90% at 20 C
It shall not be allowed to use or store within the area of petrochemicals, ammonia, and corrosive gas.Storage Temp.: -20 C~+60 C(but, the average temperature for 24 hours shall be lower than +35 C)
Under the environment with over than 40 , please note the rating current as follow.
Applicable current by the temperature
Note) IEC 60947-1 Standard is applied to the data for 40 C
TR capacity should be selected more than the value
calculated by the following formula
Operation Voltage x Operation Current x 0.5 = ( )VA
e.g.) Operation Voltage AC 220V, Operation Current 4A
220 x 4 x 0.5 = 440VA, TR capacity of more than 440 VA is
recommended
Selection of Control Relay
The capacity of UVR, Operating Relay and Timer contactor
should be higher than ATS operating current
Note : If the control power source is not stable, it is
recommended to use Automatic Voltage Regulator
Trang 26Safety Manual
Safety Notice
This safety manual describes major informations for safe operation Before handling this machinery, please be acquaintedthoroughly with this manual product handling, safety information and all other precautions before installation or maintenance
These safety notices are devided as "Danger" and "Caution" according to the hazard level
Do not enter the area under the Automatic Transfer Switches (ATS) when it is lifted
or suspended using a lifter or chain block The ATS may suddenly drop
The ATS is heavy Entering such an area may cause serious injury.
Installation should be performed by qualified persons
Prior to commencing any installation, open the upstream circuit breaker to isolate allpower/voltage sources
Otherwise, electric shock may occur.
Tighten terminal screws securely according to the specified torque
Otherwise, a fire may occur.
Fix the Drawout type ATS firmly on a flat level using mounting screws
Otherwise, drawout operation may cause the ATS to fall.
Avoid blocking of ATS's arc gas vents to ensure the adequate arc space
Blocking of the arc gas vents could result in failure of ATS.
Do not place the ATS in such area of high temperature, high humidity, dusty air,corrosive gas, strong vibration and shock or other unsual conditions
Installation in such areas could cause a fire or malfunction.
Be careful to prevent foreign material of debris, concrete powder, iron powder, etcand rainwater from entering into the ATS
These materials inside the ATS could cause a fire or malfunction.
For 4 pole ATS, connect the neutral wire of 3-phase, 4-wire cable to N-phase (on the right side)
