One must distinguish between two types of signals:
- 230 V AC power supply
- analog signals (use shielded cables) and low voltage (24 V DC).
Basic earthing principles
Use rigid wires or multi-conductor wires AWG 14 (1.95 mm 2) or bigger diameter.
The earth and mains wires should be connected in star.
All AC31 components of a cabinet should be connected to the same earth.
When the remote units are situated outside the cabinet they should be connected to the nearest earth.
The 40 and 50 series basic units are fitted with an earth plate with the DIN rail mounting system. Also, if the basic unit is screwed directly to a metal plate, the screw located at the top left of the basic unit (as seen from the front) ensures an electrical connection to the earth via the earth plate.
This earthing ensures protection against electromagnetic disturbances.
The safety earthing cable (on terminal block) should be connected to the cabinet chassis.
