The internal backup battery lifetime is approx. 6 years. If replacement of backup batter is needed, follow these
instructions:

Disconnect all terminals from the controller and remove the controller from the switchboard.
Remove the back cover and all plug-in modules.
Release the rear cover using a flat screwdriver or another suitable tool.
The battery is located in a holder on the circuit board. Remove the old battery with a small sharp screwdriver
and push with a finger the new battery into the holder.
