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

1771CP2 or 1771CP3 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.

D-shell connector located on the bottom of the power supply and
tighten the connector screws.
