5.3 Nameplate for hazardous area installations

Note

• Use shielded, twisted pair cable (wire gauge AWG 14 to 22).

• Separate cables and conduits may be required to conform to standard instrumentation

wiring practices or electrical codes.

• The non-metallic enclosure does not provide a continuous ground path between conduit

connections: use grounding type bushings and jumpers.

• For detailed information on Intrinsic Safety setups, see the full Operating instructions.

1. If you want to rotate the enclosure, use a 2 mm Allen key to loosen the 3 Allen set screws

securing the locking collar. Position the unit and retighten the screws.

2. Strip the cable jacket for approximately 70 mm from the end of the cable, and thread the

wires through the strain relief. If cable is routed through conduit, use only approved,

suitably-sized hubs for waterproof applications.

3. Connect the wires to the terminals: the polarity is identified on the terminal block.

4. Tighten the strain relief to form a good seal.

5. Close the lid and tighten screws. Do not overtighten screws. Recommended torque is 1.1

to 1.7 N-m (10 to 15 in-lb) of torque.
