 LOCK: Indicates inhibition of the UPS or a component. A lock is normally preceded by an alarm. In the event of a fault
and consequential inverter lock, the inverter will switch off and power to the load via the bypass line (this procedure is
excluded for locks caused by serious and persistent overloads and for those caused by a short circuit).
