5.3.3 Installing a Signal Cable

Connecting the Signal Cable between the Power Control Module and the
Inverter
When laying out a signal cable, separate it from power cables and keep it away from strong
interference sources to prevent communication interruption.
The COM port definitions on both sides of the power control module are the same. It is
recommended that the COM port on the switch side be connected to the inverter and the COM
port on the other side be connected to the cascaded battery.
