[9] 
OVP  – overvoltage protection optical indication            
(see section 6.8)
[10] 
LEDs – optical indication: 
AC  – AC power 
AUX1  – AUX1 output voltage 
AUX2  – AUX2 output voltage 
OVL  – PSU overload 
APS  – battery failure 
PSU   – PSU failure 
ALARM – collective failure 
EXTi  – EXTi input status 
EXTo  – EXTo relay output status 
LB   – battery charging 
[11] 
Terminals: 
~AC~      – AC power input 
EPS FLT – technical output of AC power failure indication 
    open  = AC power failure 
    closed   = AC power - O.K. 
PSU FLT – technical output of PSU failure indication 
    open  = failure 
    closed   = PSU operation - O.K. 
APS FLT – technical output of battery failure 
    open  = battery failure 
    closed   = battery status - O.K.  
ALARM  – technical output of collective failure  
    open  = failure  
    closed   = O.K. 
EXTo  – controlled relay output 
EXTi  – input of collective failure 
+BAT- – terminals for connecting the battery 
+AUX1- – AUX1 power output 
  (+AUX1= +U, -AUX=GND) 
+AUX2- – AUX2 power output 
  (+AUX2= +U, -AUX=GND) 
[12] 
TAMPER – antisabotage protection microswitch connector        
(see section 6.6)
[13]  Connector– for connecting the EMC filter
