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
extension 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. Thus, no compensation currents can flow to the transmitter via the extension cable.
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 external shield and brush it back.
• Pull the extension cable back until the brushed-back external shield is below the shield terminal. 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.
