Battery reverse connection will open internal
fuse (and produce alarm)
Detects for presence of battery on start up,
then every 60 minutes when charge current <
200mA
Electronic Circuit Breaker (ECB) operates
under the following conditions:
ELVD (electronic low voltage disconnect)
activates when battery voltage drops to 1.67V/
cell (adjustable) - auto reset
Allows ~150% load from battery without act-
ing, operates within 300ms for total load >
600%
Acts within 2ms, backed up by fuse
Green: Battery System OK, Power OK
Red: Standby
Mains Fail (Mains or PSU fail, standby
