Lock:
indicates that the UPS is locked, a lock is normally preceded by an alarm signal and, due to their gravity, causes
the inverter to be turned off and the load to be powered via the bypass line (this procedure is excluded for locks caused
by serious and persistent overloads and for a lock caused by a short circuit).
