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 801-4), it is strongly recom-

mended to follow the following

suggestions.

A

All the wiring must comply with the

local regulations.

The supply wiring should be rout-

ed away from the power cables.

Avoid to use electromagnetic con-

tactors, power relays and high

power motors nearby.

Avoid power units nearby, espe-

cially 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 shield-

ed cables on the sensor input, with

the shield connected to earth.
