9.
Holding the body hex stationary with a wrench,
hand-tighten the sealing nut and then use a
second wrench to tighten the sealing nut until the
wire is held securely in place (see Table A for
suggested torque values).
10.
Using a wrench on the body hex, make sure that
the cable fitting still is tightly screwed into the
hatch.
11.
Insert the hinge pins of the hatch into the hinges
of the ET 350, close the hatch and make sure that
the screw holes in the edges of the hatch line up
with the threaded holes in the ET 350 monitor
enclosure.
Closing the hatch
To close the hatch, follow these steps:
1.
Attach cables to their respective connectors.
2.
Close and fasten the hatch by loosely attaching
the four #6-32 Phillips screws.
3.
Using a No. 1 Phillips torque screwdriver,
gradually tighten diagonal pairs until all the
screws are equally tight at a torque of 7 inch-
pounds. This may require about three rounds of
tightening.
Replacing cables
To replace a cable, disassemble the fitting by
following these steps:
1.
Using a wrench to hold the body hex stationary,
loosen the sealing nut with a second wrench.
2.
Grip the disconnected cable and pull while
turning the cable in a counter-clockwise
direction.
The new cable you install will require a new fitting.
Important
If you need to examine cables inside the access hatch,
take off the removable plate (or extended hatch cover)
from the hatch.
