Installation Instructions Power Supply Modules Cat. No. 1771–P3, –P4, –P5 and –P5E Contents Use this document as a guide when installing the catalog number 1771-P3, -P4, -P5 or -P5E power supplies. See page Important User Information Preinstallation Considerations Connecting Input Power Setting the Power Loss Time Delay (1771 P5E only) 8 Installing the Power Supply Making Input Power Connections... - Page 2 Power Supply Modules Reproduction of the contents of this copyrighted publication, in whole or part, without written permission of Rockwell Automation, is prohibited. Throughout this publication, notes may be used to make you aware of safety considerations. The following annotations and their accompanying statements help you to identify a potential hazard.
- Page 3 Power Supply Modules Environment and Enclosure ATTENTION This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664–1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
- Page 4 Power Supply Modules Preventing Electrostatic Discharge ATTENTION This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: Touch a grounded object to discharge potential static. Wear an approved grounding wriststrap. Do not touch connectors or pins on component boards.

Page 5: Preinstallation Considerations
Power Supply Modules Preinstallation Chassis Compatibility Considerations The 1771-P3 power supply is a single-slot module, and the 1771-P4, -P5 and -P5E power supplies are 2-slot modules. These power supply modules can be used in both series A and B 1771 I/O chassis, as shown below. - Page 6 Power Supply Modules Processor Compatibility Compatibility of power supplies with selected processors is shown below. Processors with an integrated power supply as shown below can support only one additional ac power supply. Table B Power Supply and Processor Compatibility 1772 LSP 1771 AL 1772 LN1, 1772 LS...

Page 7: Connecting Input Power
Power Supply Modules The 1771–P5 and –P5E are designed to operate in ATTENTION parallel with another 1771–P5 or –P5E. Do not parallel 1771–P5 or –P5E with other ac power supplies. Limit adjacent slot module power dissipation for all supplies to 10W maximum. Power supply modules have a controlled ATTENTION “soft-start”... -
Page 8: Setting The Power Loss Time Delay (1771 P5E Only)
Power Supply Modules Setting the Power Loss Time Delay (1771 P5E only) Power loss time delay is the time period from when the power supply input voltage drops below 20.5V dc to when the power supply resets the processor enable signal on the I/O backplane. When this signal is reset, the resident PLC processor or adapter module stops processing data to/from the modules in the I/O chassis. -

Power Supply Modules Figure 1 Features of the Power Supply Modules Cat. No. 1771 P5 and P5E Cat. No. 1771 P3 Status Indicator - Keeps you informed of module operating ACTIVE ACTIVE conditions. P/S Parallel - Makes paralleling connections between 2 power supplies easy. -
Page 10: Making Input Power Connections
Power Supply Modules Turn the power supply off before inserting into the ATTENTION chassis. Turn off power to the I/O chassis before inserting into the chassis. Failure to remove power from the backplane could cause module damage, degradation of performance, or injury. Failure to remove power from the backplane could cause injury or equipment damage due to possible unexpected operation. - Page 11 Power Supply Modules 120V Line Neutral Ground Bus Equipment Grounding Ground Electrode 1771 P3 and -P4 Conductor Connecting the 1771-P5 and -P5E Power Supplies 1.

Page 12: Paralleling Power Supplies
Power Supply Modules Paralleling Power Supplies The power supply modules are designed to operate in parallel with: another 1771-P3, -P4, -P5 or -P5E power supply (Note: The 1771-P5 and -P5E power supplies are designed to operate in parallel only with another 1771-P5.) (Refer to Table A and Table C.) a 1772-LSP, -LWP or -LXP processor (Refer to Table B.) Note: Paralleling 2 modules, even when using different power... -
Page 13: Status Indicators
Power Supply Modules 3. Turn on both power supplies simultaneously. To avoid driving the first of two paralleled power ATTENTION supplies into an overcurrent condition that would shutdown the module, you must simultaneously turn on both power supplies. Module Indicators The power supply module has a green indicator light (labeled P/S ACTIVE). -
Page 14: Troubleshooting
Power Supply Modules Troubleshooting Follow the procedure below to isolate and correct possible faults. 1. Turn the power supply off and wait at least 15 seconds (-P3 and -P4) or 45 seconds (-P5 and -P5E) before you turn it on again. 2. - Page 15 Power Supply Modules 8. If you have only one power supply in your chassis and it passed step 7 (the P/S ACTIVE light turned on), verify that the power supply is not overloaded by performing steps 9 through 11. 9. Turn the power supply off and wait 15 seconds (-P3 and -P4) or 45 seconds (-P5 and -P5E).
- Page 16 Power Supply Modules 6. Perform steps 7 through 9 to test for an open circuit in the paralleling cable. 7. Turn both power supply modules off. Connect the paralleling cable to each supply. 8. Turn one power supply module on. The P/S ACTIVE indicators on both supplies should not turn on.
