For GCL and BYD batteries, if there are four wires, please cut through
the green (pin 6) and white-green (pin 3
) wires from the CANH and
CANL terminals to set up successful communication.
2.6.3 Connecting the Temperature Sensor
It is recommended that the PT1000 is connected to the inverter to sample the
temperature of the lead-acid battery or the external environment of the battery.
The temperature sensor is located next to the lead-acid battery.

Note:
For reconnection, press the part as shown in the red circle so as to pull out the
cable.
2.7 DO Connection
The inverter has two DO relays with different functions as follows:

DO1: Consumer load control. Please choose the appropriate contactor
according to the load power, e.g., the contactor types of the 3TF30 series
from SIEMENS (3TF30 01-0X). The relay is activated once the conditions of
the control mode are satisfied.

DO2: Earth fault alarm. Once the inverter receives the earth fault signal, the
relay closes the contact. The relay remains triggered until the fault is
removed.
