Safety

Step 1:
Connecting the
Modbus wires
It is recommended that shielded CAT5 or CAT5e cables compliant with ISO 11801 and
EN50173 are used for Modbus RTU cabling.
IMPORTANT! Do not use ISO/IEC-11801 U/UTP cables!
Permitted cables:
S/STP, F/STP, S/FTP, F/FTP, SF/FTP, S/UTP, F/UTP, U/FTP, U/STP
The wires in the Ethernet cables are twisted in pairs. To prevent interference in the cables
only the following pairs of wires should be twisted together:
