Lock: indicate a breakdown of the UPS or one of its parts. Locks are normally preceded by an alarm signal. In
the event of a fault and resultant breakdown of the inverter, the inverter will be switched off and the load will be
powered by the bypass line (this procedure is excluded for breakdowns caused by high and persistent
overloads and by short circuits).
