2.12 High Voltage Shutdown (HVSD)
This feature provides protection to the load from over voltage conditions originating from the rectifiers. It operates
by shutting down the offending rectifier module when a high output voltage condition occurs. Indication is through
the red Alarm (Module Fail) LED. Modules will restart automatically; however, if more than three over voltage
conditions occur in one minute, the module will latch off and remain shut down until it is reset via the CXC.
2.13 Battery Eliminator Operation
Rectifier modules maintain all specifications (except where indicated) with or without a battery attached in parallel
to the output; however, if a battery or another module supplying DC voltage in parallel is not present, there will be
no monitoring or control activity if there is an AC power failure or input fuse failure.
