Note:
• For detailed wiring instructions, please see the full manual.
• For Intrinsically Safe setups (FM/CSA Class I, Div. 1), see
Connection Drawing
• For Non-Incendive setups (FM: Class I, Div. 2), see
on page 5 of Appendix A, for drawing number 23650583.
• The non-metallic enclosure does not provide a continuous ground path between conduit
connections: use grounding-type bushings and jumpers.
• Separate cables and conduits may be required to conform to standard instrumentation
wiring practices, or electrical codes.
1. Strip the cable jacket for approximately
70 mm (2.75") from the end of the PROFIBUS PA
cable, and thread the wires through the gland
2. Connect the wires to the terminal as shown:
Probe LU (PROFIBUS PA) is not polarity-sensitive.
