– The EXTo relay switch lock from the PowerSecurity application-level (section 7.2.3)
[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- – terminals for connecting the battery
+AUX1- – AUX1 power output
(+AUX1= +U, -AUX=GND)
+AUX2- – AUX2 power output
(+AUX2= +U, -AUX=GND)
