The nickel-plated brass cable glands are EMC-types, designed so that thecable shields attach directly to the instrument housing as a ground. Typical cable wiringinstructions are detailed below.1) Unscrew the cable gland nut. Inside, the assembly is composed of a rubbergasket, and two metal washers. Note that the ethernet gland on panel and wallmount instruments does not have washers and the gasket is cut.2) If wiring a sensor cable, the cable has already been prepared so simply removethe piece of plastic protection from the exposed shieldingFor other cables, strip off external insulation as required, and 25 mm of shielding.Strip the wires about 8 mm from their ends (see illustration below)3) Pass the cable through the nut, the rubber gasket, and the two washers4) Pinch the shield so that its entire circumference is pressed between the twowashers and pass the cable into the housing, blocking the cable glandCAUTION:It is vitally important to ensure the shielding is pinched and secured between the twowashers 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 giveincorrect readings.5) Reattach and tighten the cable gland nut6) Attach the wires to the corresponding terminal block connectionsGland parts (washers not shown):1) Nut2) Rubber gasket (seal)3) Gland fitting with O-ring (attachedto instrument housing)
