(4/6 pin terminal plug)
Inverter 1 - RS485 IN
(4 pin round plug)
Pin 1 (white)

Pin 2
Pin 4 (brown)
to
Pin 3
If only one inverter is to be connected this must be terminated (see following
item Bus termination).
Connecting inverters to each other
(Solar-Log500, Solar-Log1000)
Inverters must be connected to each other using shielded data cables via the
RS485 connections located on the SINVERT PVM.
The following illustration shows the main connection diagram.
Use the SACC-M12MS-4SC connectors supplied with the inverter for data
cables.
Connect them as shown in the diagram.
Connect the bus cable on the last inverter to the RS485 OUT socket
using a terminal resistor.

Bus termination
The bus must be terminated on the RS485 OUT connection of the last inverter
with 120Ω.
To do this use the internal 120Ω resistor and short circuit the following pins in
a round 4 pin plug with two jumpers:
Inverter - RS485 OUT
(4 pin round plug)
Pin 1

Pin 2
Pin 3
to
