The redundant power supply system provides additional uptime protection for chassis that are used in critical applications. The two remotely
mounted supplies are designed to share the current required by the chassis. Two supplies are available in AC (catalog number 1756-PA75R/A or
1756-PAXTR) and DC (catalog number 1756-PB75R/A or 1756-PBXTR) versions that can be mixed or matched when used in tandem.
If one power supply fails, the remaining supply accommodates the entire load of the chassis without disruption to chassis activity.
The ControlLogix® redundant power supply system is designed to account for operational anomalies in only the power supply
(the chassis adapter and power supply cables are excluded).
The 1756-PSCA2 chassis adapter is a passive device. The chassis adapter funnels power from one or two ControlLogix redundant power supplies to
the single power connector on the ControlLogix chassis backplane.
Redundant Power Supply and Chassis Compatibility
Your chassis series determines the redundant power supply that you can use. This table lists the chassis that can be installed with each redundant
power supply.

Tools Required
When installing your chassis and power supplies, the following items are required:
Parts Required
Each redundant power supply requires four #10 Phillips screws for installation. Eight #10 Phillips screws are required to install two redundant
power supplies.
Install the Chassis
Install the Chassis Adapter
1. Align the circuit board of the 1756-PSCA2 or 1756-PSCA2XT chassis adapter with the card guides on the left side of the chassis.
2. Slide the adapter back until it is flush with the front of the chassis.
Install the Redundant Power Supplies
Follow these steps to install your redundant power supplies.
1. Drill holes in the back panel of the enclosure for the redundant power supply.
2. Insert the #10 Phillips screws into the top mounting holes, but do not tighten completely.
3. Slide the redundant power supply over the installed screws and tighten the screws.
4. Insert the bottom screws and tighten them.
5. Repeat these steps for additional power supplies.
• 3.18 mm (0.125 in.) slotted screwdriver • Crimper
• 6.35 mm (0.25 in.) slotted or #2 Phillips screwdriver • Wire stripper
• Torque screwdriver • Drill
• Needle-nose pliers
IMPORTANT Install the chassis in the enclosure and make sure that you follow the minimum spacing requirements. See the ControlLogix Chassis Installation Instructions,
publication
1756-IN621 for more information.
WARNING: EXPLOSION HAZARD
If you connect or disconnect the 1756-CPR2 cables while either backplane power source is on, an
electric arc can occur. This could cause an explosion in hazardous location installations. Repeated
electric arcing causes excessive wear to contacts on both the module and its mating connector.
Worn contacts may create electrical resistance that can affect module operation.
Be sure that power is removed or the area is nonhazardous before proceeding.
IMPORTANT Install the redundant power supplies in the enclosure and make sure that you follow the minimum spacing requirements. See the ControlLogix Chassis
Installation Instructions, publication

ControlLogix Redundant Power Supply
Connect the power as shown in the following figure.
Connect the Solid-state Relay
A solid-state relay on your redundant power supplies can be connected to any compatible monitoring or signaling device. This connection indicates
if the supplies are functioning properly.
The relays are closed during standard operation. The solid-state relay contacts open if one of these events occurs:
• One or more of the supplies fail.
• In this case, the contact opens on the failed supply (or supplies), and the input module alerts you to the failure through the controller
program.
• The connected redundant power supplies are turned OFF.
When you use the solid-state relay annunciator function, connect a compatible source voltage to a contact terminal. Then connect the other
terminal to the monitoring or signaling device.
IMPORTANT The voltage input connections of the power supplies are auto-sensing.
You do not use a jumper, for example, a 120/240V AC jumper, when connecting external power to the power supply, as shown in the previous figure.
