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.
