INPUT AND OUTPUT
NOT SYNCHRONIZED
The output converter frequency is not synchronized to the utility (input) frequency. In this
situation the automatic bypass switch is not able to transfer the load from output
converter to bypass and reverse: automatic bypass operation is inhibited: if for whatever
reason the output converter is unable to deliver the required output, output power is lost.
(see section 3.5).
Synchronization is only possible if the utility frequency remains within certain limits
(see chapter 10).
The remaining runtime. This figure is counted down during battery operation until
either the utility returns or the batteries are depleted. BATTERY RUNTIME
