PRECAUTIONS B
Despite the fact that the instrument has been designed to work in an harsh and noisy environmental (level IV of the industrial standard IEC
A
All the wiring must comply with the local regulations.
The supply wiring should be routed away from the power cables. Avoid to use electromagnetic con- tactors, 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.
If this is not achievable, use shielded cables on the sensor input, with the shield connected to earth.
