- Push the supply cable and signal cable through the cable glands
up to the terminal strip. Lay the cable in a loop before the cable
glands so that moisture does not get inside the terminal box
(Figure 3-9).

Fit end ferrules to fine-wire lines.
- Tighten the cable gland and check strain relief.

- For transmitters in remote design, also connect the housing to
the local potential equalization to which the appropriate sensor
must also be connected.
