Operation without a battery
- In this mode, the automation mode enables adjustments of the PSU output voltage
without failure indication concerning battery operation.

Connectors:
~AC~ – AC power input
+BAT – DC power battery output
+AUX – DC power output (+AUX= +U, -AUX=GND)
EPS FLT – technical output of AC network absence indication
open
= AC power failure
close
= AC power - O.K.
PSU FLT – technical output of PSU failure
open
= failure
close
= PSU working correctly - O.K.
APS FLT – technical output of battery failure
open
= battery failure
close
= battery O.K.
EXT IN – output of collective failure
[10]
V
EXT
pin – polarisation of EXT IN circuit
[11]
Communication connector
[12]
LEDs – optical indication:
AC
– presence of the AC power
AUX
– DC output voltage
OVL
– PSU overload
PSU
– PSU failure
APS
– battery failure
EXT
– EXT IN output’s status
LB
– battery charge
[13]
OVP
– optical indication for activating the over voltage system
