For power demands see Curve 1 (General Purpose, Intrinsically Safe, Non-Sparking, Non-
incendive) (Page 245).
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 (Page 43).
Note
Selecting a suitable PLC input module or power supply 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.
