need to commission the panel by means of the batteries (if the mains

power is not available). A complete hardware reset will take place.

The switch turns on the relay in the battery circuit.

switch must be operated to restart the system

EN54 part 4 states that if the battery voltage drops below a limit

specified by the manufacturer (17V) the battery shall be disconnected

to prevent deep discharge. The battery is disconnected using a relay.
