2.2.1 Environmental Considerations
The life of the IAC is adversely affected if the installation does not meet the following
guidelines:
쑺
The system must be installed on a level floor suitable for computer or electronic
equipment.
쑺
The system must be installed in a temperature and humidity controlled indoor area free
of conductive contaminants.
Failure to follow guidelines may void your warranty.
2.2.2 Preparing for Wiring the IAC
NOTE
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 IAC.
Power and control wiring for a line-up-and-match IAC are supplied with the cabinet.
Wiring requirements for an IAC installed separate from the UPS cabinet, including the
minimum AWG size of external wiring, can be found on Drawing 164201590-4 starting on
page A-19. The input power wiring connections for this equipment are rated at 90°C. If
wire is run in an ambient temperature greater than 40°C, higher temperature wire and/or
larger size wire may be necessary
.
IAC control wiring requirements can be found on
Drawing 164201590-7 starting on page A-56 and should be connected at the IAC interface
terminal block located inside the IAC.
