Install Rectifier Modules and Battery Interface Unit

Each rectifier module operates as an integral part of a complete power system with battery
backup. The modules operate in a redundant, high reliability mode to provide -48 VDC at 850
W to a common power bus.
The Battery Interface Unit controls the rectifier modules, manages the batteries, and reports the
status of system power. The unit provides the Remote Power Off (RPO) option and battery
alarm interfaces for internal and external alarms.
Install the BU3200A Battery Interface Unit (comcode 107781502) in the first slot of the
1
power distribution unit. See
NOTE:
The Battery Interface Unit and the rectifier modules are keyed and can only install 1 way.
Install the first 2 RM0850HA100 Rectifier Modules (comcode 107793796) into the
2
second and third slots of the power distribution unit.
If 2 to 3 carriers are installed in the system, install a third rectifier module (N+1).
