Refer to Figure 19 on page 35 when performing the procedure below.
1. Cut back outer sheath to desired length.
2. Cut back screen braiding or screen foil to dimension X.
3. Push the domed cap nut (item 1) and the seal insert with contact
socket of the gland (item 2+3) onto the cable as shown in the
diagram.
4. Bend over the screen braiding or screen foil by about 90º
(item 4).
5. Push the seal insert with the contact socket of the gland
(item 2+3) up to the screen braiding or screen foil.
6. Mount the lower part (item 5) on the housing.
7. Push the seal with the contact socket of the gland (item 2+3)
into the lower part (item 5).
8. Attach the domed cap nut (item 1) onto the lower part (item 5).
Grounding the Transmitter Housing
In case you need to ground the transmitter housing, the grounding
connector is found inside the housing; see Figure 2 on page 22. Note that
the probe is connected to the same potential as the housing. Make sure
that different groundings are made to the same potential. Otherwise
harmful ground currents may be generated.
If it is needed to have galvanic isolation of the power supply line from
the output signals, the HMT330 can be ordered with an optional galvanic
isolation module. This module prevents harmful grounding loops.
