8. Verify that the torque on the 1.50” (38.1 mm) nut is
60 to 80 foot-pounds (81.35 to 108.5 N-m) to ensure
a good seal.
9. Connect the cable-end connectors to the probe and the
driver.
Note: Hand tightening is not sufficient. Tighten to 140
to 150 inch-ounces (0.99 to 1.06 N-m).
10. Wrap all cable-end connectors with suitable insulating
tape to isolate them from ground.
11. Secure cables with tie wraps (inside and out) to
prevent mechanical abrasion of jacket material during
operation.
Note: The CMSS 920 High Pressure Feedthrough is not
field repairable. If it becomes damaged return it
to the factory for rebuild.

Packing Gland Assembly
The CMSS 30112000 Series Cable Packing Gland
Assembly offers a splash-proof cable exit from the machine
case. They are available in 1 or 2 cable exit versions and
with either a 1/2” (12.7 mm) or 3/4” (19 mm) NPT male
thread for screwing into the machine housing. It is an
effective and easily installed low pressure (10 atmospheres
maximum) seal. The internal oil resistant neoprene
packing as well as washers are split to allow cable
installation without connector removal.
