Wiring plan, connecting

(see also “Application
example”)
Be careful the polarity of the cables.

Select connection cable
for Ex applications
Take note the suitability of the connecting cable.
We recommend the use of screened twisted pair cable. The
wire cross-section should be 0.25-1.5 mm
2
.
Take note of the corresponding installation regulations for
Ex applications. In particular, make sure that no potential
equalisation currents flow over the cabre screen. In case of
grounding on both sides (for suppress the influence of high
frequency interference signals) this can be achived by use
of a capacitor (e.g. ceramic capacitor 1 nF, 1500 V) or
separate potential equalisation. The low frequency potential
equalisation currents are thus supressed, but the protective
effect against high frequency interference signals remains.
Preparing cables Remove approx. 30 mm of cable mantle, strip approx.
8 mm insulation.
