I/O modules wiring
The system uses a plug-in screw terminal block for the interface
between I/O modules and field devices. The following information
must be considered when connecting electrical devices to I/O mod-
ules.
1. The terminal block accepts wires from 0.5 mm to 2.5 mm.
2. Always use a continuous length of wire. Do not combine wires to
make them longer.
3. Use the shortest possible wire length.
4. Use wire trays for routing where possible.
5. Avoid running wires near high energy wiring.
6. Avoid running input wiring in close proximity to output wiring
where possible.
7. Avoid creating sharp bends in the wires.
