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.
6.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.
NOTE: Callout letters A, B, C, and D map to Figure 79
sheets 1, 2, 4, 5, and 6.
