Connecting Power
The BAC is furnished with two internally mounted circuit breakers for redundant
power (PWR A and PWR B). Two separate, unswitched, individually fused power
sources, each capable of safely handling this load, are required for power
redundancy.
The chassis provides either front or rear power access connections. Rear power
access is recommended due to ease of installation. Selecting the rear power
access method also eliminates the need for routing large 8-gauge wires to the
PEMs on the front of the chassis. The PEMs contain circuit breakers, isolation, and
other power conditioning-type circuitry and are always required for operation, even
if rear power access wiring is installed.
WARNING:
!
While power connections can be made to either the front or the rear of
the chassis, they must not be made to both at the same time.
