● For power demands see Curve 1 (General Purpose, Intrinsically Safe, Non-Sparking, Non-
incendive) (Page 237).
● 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 33).
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 ap
proval requirements and the relevant
national code of practice.
