Prepare for Installation
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-2/16
that does not have an internal power supply.
Important: The power supply is not compatible with the 1771-A1,

, Mini-PLC-2/17, or PLC-5 family processor)
-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:
, Mini-PLC-2/05,
• 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.
