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 screwdriver 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.
See “Relay Outputs” on page 55 for relay output specifications.
