Using both hands, push firmly on both spring-loaded levers until the PDM is fully seated in the
chassis slot. The PDM faceplate should be flush. Tighten both captive screws.
NOTE: Make sure that the DC circuit feed switch on the PDM faceplate matches the
current rating amperage—60 Aor 80 A. This switch applies to all inputs of this PDM, and
selecting 60 A reduces the available power output capacity of the PSMs supplied by this
PDM.

Loosen the captive screws on the clear plastic cable restraint protecting the terminal studs on the
faceplate of the PDM.
