5.5.7.4. External manual bypass auxiliary contact input.
When the circuit is closed between these terminals via the aux-
iliary contact of the external manual bypass switch (normally
open NO), the equipment is informed that the switch is in the
maintenance position. In this condition the supply of the loads
will be direct fed from the commercial grid and any anomaly
will be transmitted directly to the load connected to the output
of the UPS.
