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.
2 ControlLogix Redundant Power Supply Chassis Adapter Module In the event of a failure by one power supply, the remaining supply will accommodate the entire load of the chassis without disruption to chassis activity. For more information on the 1756-PA75R/A or 1756-PB75R/A redundant power supplies, see publication 1756-IN573. 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.

ControlLogix Redundant Power Supply Chassis Adapter Module 9 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. 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. 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. 31176-M
10 ControlLogix Redundant Power Supply Chassis Adapter Module 3. Connect the cable to the redundant power supply. 31174-M 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. 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. 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. For troubleshooting information on the Redundant Power Supply, see the Redundant Power Supply installation instructions, publication 1756-IN573.
