Sensor Cable - Labkotec idOil-20 Quick Manual

Connection to Sensors in
Potentially Explosive Areas
In oil/petrol separator systems, only sensors that are approved for
installation in potentially explosive areas can be connected. The safety
class of the external equipment must correspond to the safety class
prescribed for the entire system.

Sensor Cable

Sensor cables cannot be run in cable or conductor bundles together
with other circuits. Avoid running the sensor cable parallel to other
cables from which interference signals can be emitted that could
impair the sensor signal and thus the alarm function. The sensor it-
self cannot be grounded. If you extend the sensor cable, observe the
applicable ATEX regulations with regard to colour, quality, durability.
Use unshielded cable.
Installation in Conjunction with
Intrinsically Safe Circuits
The intrinsically safe circuits of the devices may be routed into poten-
tially explosive areas; careful attention should be paid to ensure they
are safely isolated from all non-intrinsically safe circuits. The installa-
tion of the intrinsically safe circuits must be carried out in accordance
with the applicable installation regulations. For the interconnection of
intrinsically safe field devices with the intrinsically safe circuits of the
associated devices, the respective maximum values of the field de-
vice and the associated device in terms of explosion protection must
be observed (proof of intrinsic safety). In this case, EN 60079-14/IEC
60079-14 must be observed.
