Wiring
1. Intrinsically Safe wiring
• For power demands see
Curve 1 (General Purpose, Intrinsically Safe, Non-
incendive)
on page 140.
• For wiring requirements: follow local regulations.
• Approved dust-tight and water-tight conduit seals are required for outdoor
NEMA 4X / type 4X / NEMA 6, IP67, IP68 locations.
• Refer to
Instructions specific to hazardous area installations
on page 30.
• Recommended intrinsically safe barriers are listed under
Passive Shunt Diode
Barriers
on page 27 and
Active barriers (repeating barriers)
on page 27.
Note: Selecting a suitable PLC input module, power supply, or barrier requires
knowledge about Intrinsic Safety and the application. It is the responsibility of the
installer to ensure that the intrinsically safe installation complies with both the
apparatus approval requirements and the relevant national code of practice.
WARNING: Possible Static Hazard, Do Not Rub Or Clean On Site.
