ADespite the fact that the instrument has been designed to work in an
harsh and noisy environment, it is strongly recommended to follow
the following suggestions.
All the wiring must comply with the local regulations.
The supply wiring should be routed away from the power cables. Avoid to use
electromagnetic contactors, power relays and high power motors nearby.
Avoid power units nearby, especially if controlled in phase angle. Keep the low
level sensor input wires away from the power lines and the output cables.
Power lines and output cables must also be at 100 mm (min.) away from the CPU.
If this is not achievable, use shielded cables on the sensor input, with the shield
connected to earth.
AWarning!
Whenever a failure or a malfunction of the device may cause dan-
gerous situations for persons, things or animals, please remember
that the plant must be equipped with additional devices which will
guarantee safety.
