In the event of a power failure, the VARTA element backup automatically switches to the replacement power
mode. Thus, it is possible to continue to operate selected consumers.
•
The replacement power function of the VARTA element backup is not an uninterrupted power supply
(UPS) or safety power supply.
Note:
A requirement for the replacement power mode is that the energy store is not empty.
The maximum available power is dependent on the number of battery modules installed and their charging
status. You will find the technical data in chapter 3.8 “Technical parameters of VARTA element backup”,
beginning on page 20.
