Wiring setups for hazardous area installations
There are three wiring options for hazardous area installations:
● Intrinsically safe wiring (Page 30)
● Non-sparking wiring (Page 33)
● Non-incendive wiring (US/Canada only) (Page 33)
In all cases, check the nameplate on your device, confirm the approval rating, and perform
installation and wiring according to your local safety codes.
