BATTERY BACKUP
The controller cannot be started on battery power only. Battery backup time varies with each system. Typical
backup time is between 2 and 20 hours using standard equipment and settings. When the battery voltage drops
below 20.5V the LOW BAT LED will ash. It will restore at 23.4V. If the battery voltage drops to below 16.8V,
the controller will shut down after one minute. The LOW BAT LED will ash twice as fast (strobe) during this one
minute period.

Europe: CDVI B7AH recommended). Ensure proper polarity. Various (means any type, from any
