3.2.2 UPS system power wiring preparation

NOTE
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 (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 rectifier input breaker
and the maintenance bypass. If a bypass input breaker 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.
Read and understand the following notes while planning and performing the installation:
• Refer to national and local electrical codes for acceptable external wiring practices.
• To allow for future kVA upgrades (software and/or hardware), consider using conductors sized
for full bypass rating of the UPS.
• Material and labor for external wiring requirements are to be provided by designated personnel.
• For external wiring, use 90 °C copper wire. See the appropriate information in Table 3-6:
Minimum recommended multi-core cable and fuse sizes on page 31. Wire sizes are based
on using the specified breakers.
• If wire is run in an ambient temperature greater than 30 °C, higher temperature wire and/or
larger size wire may be necessary.
• Specification is for copper wire with a 90 °C rating.
