Low Voltage Directive

This product is also tested to meet Council Directive 73/23/EEC

Low Voltage, by applying the safety requirements of EN 61131–2

Programmable Controllers, Part 2 – Equipment Requirements

and Tests.

For specific information that the above EN requires, see the

appropriate sections in this publication, as well as the following

Allen-Bradley publications:

•Industrial Automation Wiring and Grounding Guidelines

(for noise immunity), publication 1770-4.1

•Guidelines for Handling Lithium Batteries, publication AG-5.4

•Automation Systems Catalog, publication B111

The 1771-P7 power supply can power one 1771-A1B, -A2B, -A3B,

-A3B1, or -A4B I/O chassis when used with any adapter module or

programmable controller (Mini-PLC-2/02, Mini-PLC-2/05,

Mini-PLC-2/16, Mini-PLC-2/17, or PLC-5family processor)

that does not have an internal power supply.

Important: The power supply is not compatible with the 1771-A1,

-A2, or -A4 I/O chassis.

!ATTENTION: The 1771-P7 is a stand-alone

power supply. Do not connect it in parallel with any

other power supply. Connecting it in parallel could

result in processor memory loss or injury due to

unexpected machine operation.

!ATTENTION: Under some conditions, electrostatic

discharge can degrade performance or damage system

components. Observe the following precautions to

guard against electrostatic damage:

•Touch a grounded object to rid yourself of charge

before handling a module.

•Do not touch the backplane connector or

connector pins.

•When not in use, keep modules in their

static-shield bags.

Before installing the power supply, you should:

•mount the I/O chassis that the power supply will be connected to.

See the Universal I/O Chassis Installation Data (1771-2.210) for

information on mounting the I/O chassis.

•set the power supply configuration jumper on the I/O chassis.

The 1771-P7 is an external power supply. Set the configuration

jumper to the N position.

1. Attach the mounting screws to the side of the I/O chassis

as shown:

with the 1771-P7. Longer screws may intrude into

the I/O chassis and interfere with module insertion.

Mounting the Power Supply Separately

When mounted separately, the power supply may be mounted above

or next to the I/O chassis. It may not be mounted below, since it is

necessary to allow convection cooling of both the power supply and

the I/O chassis. A minimum vertical distance of 6 inches should be

maintained.

1. Mount the power supply vertically, above and within the

specified cable-feet (for your cable) of the D-shell connector on

the I/O chassis.

Allow for a generous bend of the

1771CP2 or 1771CP3 cable to reduce

stress on the connectors mounted on

the chassis and the power supply.

Use the rear mounting flanges on the

power supply to mount it to a panel.
