• The distance between the measuring cables and the power cables should be at least 1 m.

• The measuring cables should be laid in separate cable conduits or steel pipes connected to earth potential.

• Power cables should be crossed at right angles.

Load cell supply circuit

The load cell supply voltage is fixed to 12 V DC and protected against short circuit.

Load resistance of load cells ≥75 ¥, e.g. 8 load cells of 650 ¥ each.
