After removing the back cover insert the plug-in module. The plug-in module must be inserted under holders.
Start with holders marked by arrows. After inserting plug-in module under holders press it down. This locks
the module in place.
After locking the plug-in module into holders, place back the back cover (small cover for connectors has to be
removed from back cover). Finally insert the small cover for connectors. Small covers are unique for each
plug-in module.
4.6 Maintenance
4.6.1 Backup battery replacement
This battery serves to maintain the run of RTC (real time clock) so that controller does not lose information
about time and date when disconnected from power supply.
The internal backup battery lifetime is approx. 6 years. If replacement of backup battery 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.
