1756-PSCA chassis adapter module
The 1756-PSCA power supply chassis adapter module is a passive device designed to funnel power from one or two ControlLogix redundant power supplies to the single power connector on the ControlLogix Series B chassis (Series B only) backplane
The redundant power supply system provides additional uptime protection for chassis used in critical applications The two
remotely-mounted supplies are designed to share the current required by the chassis and are available in AC and DC versions that can be mixed or matched when used in tandem

Overview of the Installation Process
Follow these steps when installing and powering your redundant power supply chassis adapter module
1 Install the Chassis Adapter Module
2 Connect the Chassis Adapter Module to the Redundant Power
Supplies
The steps are described in detail, along with other important information, throughout this installation instructions
ATTENTION
!
Electrostatic discharge can damage integrated circuits or semiconductors if you touch backplane connector pins Follow these guidelines when you handle the 1756-PSCA
• Touch a grounded object to discharge static potential
• Do not touch the backplane connector or connector pins
• If available, use a static-safe work station
• When not in use, keep the power supply in its static-shield packaging

Connect the Chassis Adapter Module to the Redundant
Power Supplies
Use the 1756-CPR cables to connect your chassis adapter module to your redundant power supplies
1 Leave a minimum of 4 in (10.2 cm) space between the left side
of the chassis adapter module and the cabinet housing your control system The 1756-CPR cable will not connect to the module in less than 4 in (10.2 cm) of space
2 Connect the cable to the chassis adapter module.
ATTENTION
!
Make sure the redundant power supply is turned off before connecting the 1756-CPR cables to the chassis adapter module or the power supply

Trang 103 Connect the cable to the redundant power supply.
4 Tighten the screws to hold the cables in place Make sure you
completely tighten the cable screws to hold the cable in place for the life of the product
Troubleshoot the Chassis Adapter Module
Your chassis uses a green status indicator (LED) to display when power is applied to the chassis
• If the indicator is lit up, the chassis is receiving power from one or both of the redundant power supplies
• If the indicator is OFF, the chassis is not receiving power from the redundant power supplies In this case, check the power supplies for a reason
WARNING
!
EXPLOSION HAZARD
When used in hazardous area, do not attempt to connect or disconnect cables unless power has been removed, or the area is known to be nonhazardous
