Preparing for Wiring the UPS System

NOTE If installing, as part of the UPS system, a maintenance bypass without a rectifier input breaker, a
minimum of two separate feeds with upstream feeder breakers, or one feed with two upstream feeder
breakers, must be provided: one for the UPS and one for the maintenance bypass input. DO NOT use one feed
or a single feeder breaker to supply both the UPS and the maintenance bypass.
For external wiring requirements, including the minimum AWG size of external wiring,
see Table G through Table I starting on page A-13. The power wiring connections for
this equipment are rated at 90° C. If wire is run in an ambient temperature greater
than 30° C, higher temperature wire and/or larger size wire may be necessary.
Control wiring for Emergency Power-off (EPO) and optional accessories (such as
building alarms and monitoring interface) should be connected at the customer
interface terminal blocks located inside the UPS.
LAN and telephone drops, for use with X-Slot connectivity cards, must be supplied by
facility planners or the customer.
The cabinet is shipped bolted to a wooden pallet and protected with outer protective
packaging material (see Figure 3‐1).
