22 InfraStruXure System—Installation and Start-Up

Connect User Input Contacts and Relay

Outputs to the User Connection Plate

Overview

Make contact closure connections

(NO or NC) at the user connection

plate to monitor dry contacts. You

can make eight connections—four

input contacts and four relay outputs.

The figure at the right shows the

location of the user connection plate

on the roof of the PDU enclosure.

You can make connections from

inside the enclosure, or you can

remove the user connection plate and

make your connections.

Remove the plate using a Phillips or

standard screw driver to loosen the

two captive screws. Use the

knockout in the plate to route cables

to and from the user connections on

the plate. If you remove the plate,

make sure that you do not disturb the

existing connections.
