Chapter 3 Equipment Installation
and Wiring
Only company authorized personnel should install and connect the equipment.
For details, see SigenStor Home Installation Guide - Three-phase System A1.
Below is the networking figure for Modbus RTU mode with Checkwatt CM10
device using RS485.
The RS485 cable from SigenStor，has three wires, among which RS485A1 should
be connected to the + port of the Checkwatt device, RS485B1 should be
connected to the - port of the Checkwatt device and the PE line should be
connected to the GND port.
Please also refer to the wiring detail figure on page 14.

User Manual
Below is the networking figure for Modbus TCP mode with Checkwatt CM10
device using FE cable.
The FE cable connecting the SigenStor should be plug in the checkwatt CM10 LAN2.
And the LAN1 of Checkwatt CM10 should be plug in to the router.
