UPS System Power Wiring Preparation
Read and understand the following notes while planning and performing the
installation:
S
Refer to national and local electrical codes for acceptable external wiring practices.
S
To allow for future kVA upgrades, consider installing a derated UPS using wiring
and external overcurrent protection breakers sized for a fully rated UPS.
S
To allow for a future upgrade, install a two UPM model using conductors and
external overcurrent protection breakers sized the same as a fully rated 825 kVA
model.
S
For external wiring, use 90°C copper or aluminum wire. Wire sizes listed in
Table 3‐4 through Table 3‐7 are for copper wiring only. If wire is run in an ambient
temperature greater than 30°C, higher temperature wire and/or larger size wire
may be necessary. Wire sizes are based on using the specified breakers.
S
Wire ampacities are chosen from Table 310-16 of the National Electrical Code
(NEC
). Specification is for copper wire with a 90°C rating.
®
S
Material and labor for external wiring requirements are to be supplied by
designated personnel.
S
If installing a maintenance bypass, a minimum of two separate feeds with
upstream feeder breakers, or a single feed with two upstream feeder breakers,
must be provided: one for the UPS or rectifier input breaker (RIB) (if installed) and
one for the maintenance bypass input. DO NOT use a single feed or a single feeder
breaker to supply both the UPS or RIB and the maintenance bypass. If a bypass
input breaker (BIB) is installed in the maintenance bypass and a single-feed UPS is
being installed, a single feed to the maintenance bypass is acceptable for supplying
both the UPS and the bypass.
S
The bypass feed into this equipment uses three or four wires. The rectifier feed
into this equipment uses three wires. The phases must be symmetrical about
ground (from a Wye source) for proper equipment operation.
