6.7.1. Operating principle.
The integrated manual bypass in the UPS is a very useful element,
but undue use can have irreversible consequences both for the
UPS or UPSs that make up the parallel system and for the loads
connected to its output. Therefore, it is important to respect the
manoeuvring over the switches as it is described in the following
paragraphs.
6.7.2. Transference to maintenance bypass.
To shift from normal operating to maintenance bypass:
Shutdown the inverter.
