enter the enclosure.
2. Loosen the nut on the cable fitting and remove the white plastic dowel.
3. Slide the transducer cable through the cable gland nut and fitting.
4. Insert each conductor wire into the terminal block by pressing down on the
orange tab, inserting the bare end of the conductor into the terminal block,
and then releasing the tab. Refer to Figure 15 and Table 2 for sensor wiring
information. To prevent the possibility of a short circuit, do not allow bare
leads to touch each other during or after wiring.

gland.
