Read and understand the following notes while planning and performing the installation:
1.
Refer to national and local electrical codes for acceptable external wiring practices.
2.
Material and labor for external wiring requirements are to be provided by designated
personnel.
3.
For external wiring, use 90
C copper wire. See the appropriate information in Table E
through Table J. Wire sizes are based on using the specified breakers.
4.
Wire ampacities are chosen from Table 310-16 of the NEC. Wire is 90
C specification.
5.
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.
