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.
