2.
Switch on DIP switch 2 to turn on the termination
resistor.

6.8.3 Wiring multiple inverters for RS 485

Wiring RS 485 depends on whether you want to con-
nect a single or multiple inverters.
1.
On the fi rst inverter in the RS485 chain, connect
the cable that comes from the datalogger to the
right Pin DC+ and Pin DC-.
2.
Connect the cable that goes to the second in-
verter in the RS485 chain to the left Pin DC+ and
Pin DC-.

3.
On the second inverter, connect the cable that
comes from the fi rst inverter and the cable that
goes to the next inverter. Repeat these steps for
all other inverters in the RS485 chain, except for
the last inverter.
4.
On the last inverter in the RS485 chain, connect
the cable that comes from the datalogger to the
right Pin DC+ and Pin DC-.
5.
On the last inverter in the RS485 chain, switch on
DIP switch 2 to turn on the termination resistor.
