Advice on noise immunity
All connections are protected against ex-
ternal sources of interference. The installa-
tion location should be chosen so that
inductive or capacitive interference does
not affect the device or its connecting
lines! Interference (e.g. from switch-mode
power supplies, motors, clocked con-
trollers or contactors) can be reduced by
means of appropriate cable routing and
wiring.
Measures to be taken:
Use only shielded cable for signal and con-
trol lines. Connect cable shield at both
ends.
The conductor cross-section of the cables
should be a minimum of 0.14 mm².
The shield connection to the equipotential
bonding should be as short as possible and
with a contact area as large as possible
(low-impedance). Only connect the shields
to the control panel, if the latter is also
earthed.
Install the device as far away as possible
from noise-containing cables.
Avoid routing signal or control cables paral-
lel to power lines.
Cables and their insulation should be in ac-
cordance with the intended temperature
and voltage ranges.
