If the inverter is the last/only Modbus device in the Modbus daisy chain, make sure the
Modbus termination switch S402 is in the ON position (Up towards the LCD) enabling
the Modbus termination resistor. Do

not

turn the switch to the ON position in any of the

other inverters. See Figure 2.35 and 2.43.

Follow steps 5 through 8 in section 2.4.1 Third Party Monitoring Systems Modbus
Connections to connect other inverters to the Modbus daisy chain.

Warning:

Risk of Electric Shock.

Make sure all shield wires are properly secured and insulated to prevent shorting to
any other components inside the inverter.

Close the wiring box.

Reconnect AC and DC power and turn the inverter on when it is safe.

10.

Configure the Inverter Modbus ID and Baud rate using the front panel LCD display. See
section 2.4.3 for more details.
