7.1.4 Connection of the extension cable to the junction box
7.1.4.1 Connection without potential separation (standard)
The connection of the extension cable to the junction box without potential separation ensures that the transducer,
junction box and transmitter are on the same potential. The extension cable should always be connected in this manner,
especially if power current cables are nearby. If earthing on the same potential cannot be ensured, see section 7.1.4.2.
• 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 and the compression part.
• Prepare the extension cable.
• Shorten the external shield and brush it back over the compression part.
• Screw the gasket ring side of the basic part into the junction box.
• Insert the extension cable into the junction box.
• Fix the cable gland by screwing the cap nut onto the basic part.
• Connect the extension cable to the terminals of the junction box.

Notice!
For good electromagnetic compatibility (EMC), it is important to ensure good electrical contact between the external
shield and the cap nut (and thus the housing).
