We recommend the use of screened twisted pair cable. The
wire cross-section should be 0.25-1.5 mm
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 very high level, high
frequency interference signals) this can be achived by use
of a blocking 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.
Prepare the cable for the connection.
Remove approx. 20 mm of cable mantle, strip approx.
8 mm insulation.
