7.1.4.2 Connection with potential separation
If earthing on the same potential cannot be ensured e.g., in measurement arrangements with long extension cables, the ex -
tension cable and the junction box have to be electrically insulated from each other. The junction box and the transducers
have to be on the same potential. By doing this, no compensation currents can flow to the transmitter via the extension cables.
For measurement arrangements where the junction box and the transducers have to be electrically insulated from each
other, see the document TIFLUXUS_GalvSep.
• Remove the blind plug for the connection of the extension cable.
• 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.
• Insert the extension cable into the junction box.
• Prepare the extension cable.
• Cut the outer shield and brush it back.
• Pull the extension cable back until the back brushed external shield is below the shield terminal, see Fig. 7.7. The extension
cable has to remain completely insulated up to the shield terminal.
• Screw the gasket ring side of the basic part into the junction box.
• Fix the cable gland by screwing the cap nut onto the basic part.

Important!
Observe the max. permissible voltage of 60 V DC between the earth potentials.
