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 (15.2cm)
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.
2. Connect one end of the power cable to the D-shell connector
located on the bottom of the power supply and tighten the
connector screws until snug, plus 1/4 turn.
