The battery wiring used between the battery and the UPS should not allow a

voltage drop of more than 1% of nominal DC voltage at rated battery current.

4.3.3

Control wiring for features and options should be connected at the customer

interface terminal blocks located inside the UPS.

Do not directly connect contactor contacts to the mains related circuits.

Reinforced insulation is required before connecting to the mains.

Read and understand the following notes while planning and performing the

installation:

•

Interface wiring should be rated for 24V, 1A minimum.

•

For interface wiring from 30V to 600V, the wire should be rated for 600V, 1A

minimum.

•

Because of the remote EPO and signal input wiring route in the UPS

cabinet, the wire should be rated for a minimum of 300V.

•

Use twisted-pair wires for each input and return or common.

•

All interface wiring and conduit is to be supplied by the customer.

•

When installing external interface wiring between a remote EPO or signal

input and the UPS interface terminals, conduit must be installed between

each device and the UPS cabinet.

•

If using the power terminal wiring channel, keep interface wiring separate

from power wiring or use shielded wire.

•

Interface wiring circuits are PELV circuits.
