F
BAT
fuse in the battery circuit, F3,15A / 250V
Terminals:
~AC~
– AC power input
EPS
– technical output of AC power failure indication
hi-Z state
= AC power failure
0V state
= AC power - O.K.
PSU
– technical output of PSU failure indication
hi-Z state
= failure
0V state
= PSU status O.K.
LoB
– technical output of low battery voltage indication
hi-Z state
= battery voltage U
BAT
<23V
0V state
= battery O.K.
+BAT-
–
terminals for battery connection
+AUX-
– DC power output, (+AUX= +U, -AUX=GND)
Description: hi-Z
– high impedance, 0V – connection to the ground GND
LEDs
– optical indication:
AC
– AC power
LB
– battery charging
AUX
– output voltage DC
Optional, external optical indication output terminal
