Fire Mode Operation
Fire Mode operation is for use in emergency situations. When enabled, Fire Mode allows the
inverter to provide continuous operation ignoring the majority of faults. Primarily used for fire
pump operation, but can be applied when continuous operation is required due to emergencies.
When enabled, Fire mode forces the inverter to ignore all minor faults and repeats a Reset/Restart
of major faults, regardless of the Reset/Restart count limit.
