NOTE: 1. 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 IAC bypass input. DO NOT use
one feed or a single-feeder breaker to
supply both the UPS and the IAC
.
2. Remove jumpers for dual-feed.
3. If the load requires a neutral, a bypass
neutral feeder must be supplied.
