Power distribution plate
Provides an interface for output hard-wiring of loads. It is used in place of the power
distribution plate for cord connected equipment originally furnished with the UPS.
Input cable plate
Used to replace the input cable plate originally furnished with the UPS. It allows hard-wiring
of the input connections.
Wiring inspection cover
When removed, the wiring inspection cover reveals the output wiring connections to the UPS.
It is necessary to inspect the connections during installation as the wires may move when the
power distribution plate is attached.
Electrical fittings "knock-outs"
Knock-outs appropriate for use with ½" (output only), ¾" and 1" electrical cable clamp fittings
are provided at the input cable plate, and at the output power distribution plate.
UPS output power connector
This self locking connector plugs into an internal receptacle. The mating connector is revealed
when the power distribution plate and top cover of the UPS Isolation Unit are removed. The
connector provides all necessary output voltages to the output wiring terminals.
Earth bonding ring terminal
The earth bonding ring terminal connects the output earthing terminations on the power
distribution plate to the input protective earth. This terminal is bolted to the Isolation Unit's
earthing stud. See the Installation section of this manual.
