2.2.2 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 E through Table G starting on page A-12. 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 c ustomer 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.
