6.3.3.2 With Potential Separation
If earthing on the same potential cannot be ensured e.g., in measurement arrangements with long extension cables, ex-
tension cables and junctions boxes have to be insulated from each other. The junction box and the transducers have to be
on the same potential. Thus, no transient currents can enter the transmitter via the extension cable.
• Remove the blind plug for the connection of the extension cable (see Fig. 6.9).
• Open the cable gland of the extension cable. The compression part remains in the cap nut.
• Push the extension cable through the cap nut, the compression part and the basic part of the cable gland.
