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 cable 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.
1. Prepare the cable for the connection.
Remove approx. 30 mm of cable mantle, strip approx.
8 mm insulation.
2. Remove the instrument front cover (see chapter 4.3.).
3. Loosen compression nut of the cable entry.
4. Insert the cable into the instrument through the cable
entry.
