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.

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.
