How to Connect User Input Contacts and
Relay Outputs to the PDU 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 connection on the plate. If you
remove the plate, make sure that you
do not disturb the existing
connections.
