F
BAT
fuse in the battery circuit
[3]
Connectors:
+BAT- DC supply output of the battery
(+BAT= red, -BAT=black)
+AUX- DC supply output
(+AUX= +U, -AUX=GND)
FAC - technical output for no AC network - relay type
In Figure 2 configuration of contacts shows relay voltage-free state, which corresponds to the state
signalling no AC network (AC network failure)

LED indication:
AC - LED for AC voltage
LB - LED for battery charge
AUX - LED for DC voltage
