PRECAUTIONS
B
Despite the fact that the instru-
ment has been designed to work
in a harsh and noisy environment
(level IV of the industrial standard
IEC 801-4), it is recommended
these 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 using electromagnetic con-
tactors, power Relays and high
power motors nearby.
Avoid power units nearby, espe-
cially if controlled in phase angle
mode.
Keep the low level sensor input
wires away from the power lines
and the output wires.
If this is not feasible, use shield-
ed cables on the sensor input,
with the shield connected to
ground.
