4.5.3 Cable gland type 2 wiring instructions
Typical cable wiring instructions are detailed below for cable gland type 2
Figure 5 Cable gland type 2
1 Gland nut
2 Gasket
1. Unscrew the cable gland nut. Inside, the assembly is composed of a rubber gasket, two metal
cones and a spring. Note that the ethernet gland on panel and wall mount instruments does not
have washers and the gasket is cut.
2. If wiring a sensor cable, the cable has already been prepared.
For other cables (4 mm minimum to 6.5 mm maximum OD), strip off external insulation as
required, and 25 mm of shielding. Strip the wires about 8 mm from the ends
Figure 6 Wire preparation
3. Pass the cable through the nut, the rubber gasket, two metal cones and the spring and remove
the plastic protection part (tape) from the exposed shielding.
4. Position the spring on the shield, pass the cable into the housing and blocking the cable gland
(Figure 7).
It is vitally important to ensure the shielding is in contact with the spring after tightening the cable gland to
ensure the shielding attaches directly to the instrument housing as a ground. Failure to do this could cause
damage to the instrument, and for sensor cables give incorrect readings.
