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.
