4.5 Connectors assembly instructions
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.
4.5.1 Cable glands
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.
Determine which cable gland is in the instrument:
• Cable gland type 1 with washers
instructions on page 8.
• Cable gland type 2 with springs
instructions on page 10.
4.5.2 Cable gland type 1 wiring instructions
Typical cable wiring instructions are detailed below for cable gland type 1
Figure 2 Cable gland type 1 (washers not shown)
1 Nut
2 Rubber gasket (seal)
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 (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
