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 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.
C. Connect the RTS interface
External temperature sensor
Remote Temperature Sensor
Suppose the remote temperature sensor is not connected to the inverter/charger. The
default setting for battery charging or discharging temperature is 25°C without
temperature compensation.
D. BMS-Link connection port
（RJ45）
