9. Connecting the absolute battery
The absolute batteries shipped with the controller are unused, and the battery connectors
are left disconnected to prevent discharge.
After installing the controller, always be sure to connect the absolute batteries before
connecting the robot cable.
An absolute battery should be connected to the "BAT A" or "BAT B" connector on the
front of the controller. When two batteries are used and connected to the both "BAT A"
and "BAT B" connectors (standard), the data retention time (backup time) will be doubled
compared to that of one battery.
