DAS PVI 23-28-36TL If the inverter is the last device in the daisy chain, make sure the Modbus termination switch S402 is in the ON position (Up towards the LCD) for Modbus termination. Do not turn the switch to the ON position in any of the other inverters. Only connect the cable shield to ground (GND) at the DAS. Do not connect the shield to any of the inverters. Fig. 3: Notice how the cable shield is daisy chained together and not landed inside the inverter.
