parameters.
② Dry contact interface
 Working principle:
When the battery voltage reaches the dry contact ON voltage (DON), the dry contact is
connected. Its coil is energized. The dry contact can drive resistive loads of no more than
125VAC /1A, 30VDC/1A. According to different battery types of the inverter charger, the
default values of the dry contact ON(DON) voltage and the dry contact OFF(DOF) voltage
are different. Please refer to the chapter 3.5 Settings > item 19 DON and item 20 DOF for
details.
