[2]
START
pushbutton (power-supply activation from the battery)
[3]
J, jumper
- configuration of UVP battery protection function
••••
J =
protection function (disconnection) of the battery off
••••
J =
protection function (disconnection) of the battery on
Legend:

+AUX-
+AUX1-
+AUX2-
+AUX3-
Outputs for DC power supply (+AUX= +U, -AUX=GND)
[6]
O1, O2, O3, AUX -
optical
signalisation of power supply operation
[7]
AC

+BAT -
DC power supply output of the battery
(+BAT = red, -BAT = black)
[12]
BS
- technical output of AC shortage – OC type
hi-Z level = status: AC power supply
L level = status: AC power supply failure
[13]
AW
- failure technical output – OC type
Activation: SCP, OLP, UVP, converter failure
L level = status: correct operation
hi-Z level = status: failure, overload
