Back-up
In order to preserve back-up values for RTC and system data in the event of power off, the
battery must be connected.
First Use
The battery is protected by a removable cover
on the side of the controller.
The battery is supplied installed inside the
unit, with a plastic tab preventing contact
which must be removed by the user.
Battery Installation and Replacement
▪ Use proper precautions to prevent Electro-Static Discharge (ESD) while servicing
the battery.
Caution ▪ To preserve back-up values for RTC and system data during battery

and causes them to be deleted.

2. If you are replacing the battery, remove the
