Automatic battery charger
The "trickle charger" charges the battery completely and is
disconnected once the unit starts up.
To prolong the lifespan of the batteries, the battery
continuously discharges via the lock-out switch of the battery
charger and a small resistor.
When the unit is shut down for a longer period or will be
stored, make sure to switch off the lock-out switch of the
battery charger to prevent the battery from discharging
!
completely.
Connection block for monitoring
X25 ...Connection block
Allows easy connection for sensing of mains voltage and
control of the mains and the plant contactor.
Refer to circuit diagram of the "Automatic mains failure" option
!
for the correct connection.
