Rechner Sensors TRUE LEVEL Notice D'utilisation page 21

Installation of cables
Wiring of the sensor should be routed separately or screened from heavy conductor lines, as in ex-
treme cases inductive peak voltages can destroy the sensors despite the integrated protective circuit.
Screened cable or twisted lines are recommended, especially for longer cable runs > 5 m. Direct control
of electric light bulbs is to be avoided, because during the switch-on moment cold current is many times
the rated current and can destroy the output stage of the sensor.
Units with strong fields nearby, e. g. high power walkie-talkies, or noise sources in the lower fre-
quency range, e. g. long, middle or short-wave transmitters should not be operated close to the sensors
or additional measures have to be taken in order to eliminate incorrect operation.
