[8]
Z2 jumper temporary lock of the battery test
(section 8.5)
[9]
OVP
– overvoltage protection optical indication
(section 6.9)
[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
close
= AC power - O.K.
PSU FLT – technical output of PSU failure indication
open
= failure
close
= PSU operation - O.K.
APS FLT – technical output of battery failure
open
= battery failure
close
= battery status - O.K.
ALARM – technical output of collective failure
open
= failure
close
= O.K.
EXTo – controlled relay output
EXTi
– input of collective failure
+BAT- – battery power output
+AUX1- – AUX1 power output
(+AUX1= +U, -AUX=GND)
+AUX2- – AUX2 power output
(+AUX2= +U, -AUX=GND)
