4.6.1 Backup battery replacement
The internal backup battery lifetime is approx. 6 years. If replacement of backup batter is needed, follow these
instructions:
Connect the controller to a PC and save an archive for backup purposes (not necessary but recommended).
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.
Put the rear cover back. Use slight pressure to lock the snaps into the housing. Pay attention that the cover
is in correct position and not upside down!
Put back the plugin modules and back cover.
Power the controller on, adjust date and time and check all setpoints.
