P L E A S E N O T E!
An operating fault can lead to total loss of power supply to the attached power
consumer loads! A power failure for a switched in manual bypass will lead to
crashing of the power consumer loads!
Fault in the inverter or an overload (bypass operation)
In the case of a fault occurring in the inverter or an overload, a switch-over device switches the load back to
the mains. This means that, in the case of a power failure, the connected consumers will no longer be
supplied with power.

Manual bypass (service bypass)
If there is a fault in the UPS unit and service work must be undertaken, the UPS unit is fitted with an internal
bypass for that purpose. When actuating the manual bypass, the load is directly supplied from the mains.
This means that, in the case of a power failure, the connected consumers will no longer be supplied with
power. When using the manual bypass it is essential to observe the chapter “UPS internal manual bypass”.
Other procedures could lead to destruction of the UPS unit or crashing of the power consumer loads.
