Strip the leads as shown in Fig. 3. Pass the leads through
the gland nut (1.7) pinch ring (1.8) and seal (1.9). Insert the
leads into the body. Connect the cores according to the
respective wiring diagram (Fig. 4 or 5).
Push the seal and the pinch ring which are loose on the leads
into the body. Fit and tighten the gland nut on the body.
Align the seal (1.10) on the sealing surface of the body. Re-
assemble the cover and the body and press the cover into
place until the latch (1.6) audibly clicks.
Finally, insert the connector into the socket plug at the rear
of the transmitter.

7.2 Connecting transmitter with screw terminals
and cable glands
In the case of transmitters fitted with screw terminals and
cable glands, there are 4 screw terminals (4.1) plus 1 ground
4
terminal (4.2) which are accessible after removing the cover
(3.1) (see Fig. 6). The maximum wire gauge the terminals can
accept is 1.5 mm
Fig. 6. Rear (3) with terminals (4.1) and (4.2) and cable glands (4).
Left:
Cover (3.1) closed.
Right: Exposed.
Remove the 3 screws (3.2) and take off the cover (3.1).
Undo the gland nut and remove the pinch ring and seal from
the gland opening. Place these parts over the cable in the
correct order and pass the end of the cable through the gland
hole into the rear of the transmitter.
Strip the insulation from a suitable length of the leads and
connect them to the terminals (4.1) and (4.2) according to
the respective wiring diagram (Fig. 7 or 8).
Then fit the gland seal, pinch ring and nut. Tighten the gland
nut and replace the cover.
