Description of the LEDs
The FKS fuse (20 A, 32 V) can be reached via the front panel (F1 connection).
The battery is secured by fuse F1. Without fuse F1 the UPS cannot be operated.
With the rotary switch you can set different UPS times . By using the switch
positions from 0 to 3 it is possible to change the UPS time in steps of one minute.
The UPS time is the time period in which the connected device is provided with
output voltage of the UPS - after the switch off of the input voltage. The switch
position is in the delivery status "1".
