Potential Electrocution Hazard. In order to maintain the NEMA/IP environmental ratings of the enclosure, use only
conduit fittings and cable glands rated for at least NEMA 4X/IP65 to route cables into the instrument.
Cable gland wiring instructions
A waterproof cable gland is provided each time a cable must be connected inside the instrument.
The nickel-plated brass cable glands are EMC-types, designed so that the cable shields attach
directly to the instrument housing as a ground. Typical cable wiring instructions are detailed below.
1. Unscrew the cable gland nut. Inside, the assembly is composed of a rubber gasket, and two
metal washers. 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 so simply remove the piece of
plastic protection from the exposed shielding. For other cables, strip off external insulation as
required, and 25 mm of shielding. Strip the wires about 8 mm from their ends.
3. Pass the cable through the nut, the rubber gasket, and the two washers.
4. Pinch the shield so that its entire circumference is pressed between the two washers and pass
the cable into the housing, blocking the cable gland.
