Do not connect the other end of cables to the battery or -48V DC source at this
stage.
WARNING: DC source voltage must be between 45V and 58 V.
CAUTION: Reverse polarity connections will damage the unit and are not
covered by the warranty. Ensure correct polarity (positive to positive, negative
to negative) before completing connections to the battery or dc source, and the
inverter unit.

Step 5 - Connect inverter alarm (if required)
CN11 on the inverter shelf backplane is the inverter alarm. It will send out
alarm signal if either inverter in the shelf fails.
This alarm is typically used if the inverters are stand-alone (no controller).
If required, connect from CN11 to a suitable digital input of an external alarm
monitoring system. See details on page 57
