Installing the NEMA 4X Hatch
Connecting supplied sealed fittings
Make clearance hole. Clearance hole can be
1.
made anywhere on the back of the hatch, as long
as the hatch can open and close freely on its
hinges after the cables and/or cable fittings are
installed.
The number of holes needed will depend on
whether your ET 350 has a KVM extender
(maximum of four holes) or not (three holes).
Table B shows the clearance holes required in
each case
: There are three indentations on the back of
Note
the hatch that may be used as a guide when
creating holes. However, these are only guides; if
you need four holes, you will need to decide how
best to space them.

Important
If the diameter of the cable is close to the ranges of both
the small and large fittings shown in Table A, try running
the cable through the smaller fitting before beginning to
connect the fittings. If the cable will go through the small
fitting without being forced, 3M Touch Systems
recommends using that fitting.

The cable fitting comes loosely assembled.
2.
Disassemble the cable fitting into its four
components: locking nut, o-ring, body hex
(which encloses the compression sleeve), and
sealing nut.
Install the o-ring onto the surface of the body hex
3.
and then insert the body hex (with o-ring
attached) into the clearance hole on the outside
of the hatch.
On the inside of the hatch, attach the locking nut
4.
to the body hex.
Holding the body hex stationary with a wrench,
5.
hand-tighten the locking nut and then use a
second wrench to tighten the locking nut until the
cable fitting is held in place securely (see
Table A for suggested torque values).
Slide the sealing nut onto the cable and then,
6.
from the outside of the hatch, feed the cable
through the cable fitting.
Gently screw the sealing nut onto the body hex,
7.
but do not tighten it. Leave the sealing nut loose
to allow the cable to move through the fitting.
Slide the cable through the body hex and into the
8.
hatch until you are satisfied with the amount of
cable inside and outside of the hatch.
Make sure there is enough slack in the cable to
allow the hatch to fully open and close on its
hinges without straining the cables or connectors.
