4.3 Connecting an XAMP
This section explains how to correctly install and assemble an
XAMP
into a transducer junction box. Although one type
of junction box is used as an example in the steps below, the procedure applies to all three possible junction box options
(see drawing #752-063 in
Figure 88 on page 73 ).
1. Place a 3/4” NPT compression fitting on the stem of the transducer closer to the BNC end.
2. Torque the fitting into one of the 3/4” NPT ports of the junction box, with at least five threads engaged. After
the fitting is torqued into place, ensure that the BNC head of the transducer extends slightly past the ground
screw bosses as shown in
Figure 80 below:

3. If the BNC head extends too far into the junction box, it will make the assembly more difficult by reducing the
amount of area available to properly store the excess cable. If the BNC head is not positioned approximately
where it is pictured in the image above, loosen the compression fitting and adjust the transducer. Then,
re-tighten the compression fitting after this is completed.
4. Torque the cable gland coming from the electronics main housing into the other 3/4” NPT port until there are at
least five threads of engagement (see
Figure 81 below).
