Battery management: No influence for backup battery management without monitoring module when rear
battery is 7AH or 12AH. When rear battery is between 17－30A, supervisory sends order to set battery
arrangement, at then charging battery current limiting is 3A.
3. Interface
There is a three-core AC input socket for power supply input which are integrated in the rear panel. There
are two DC output interfaces, one backup battery interface, monitoring interface RS232.
IX. Environmental Testing Requirements
