EXPLOSION PROOF
XPClass I / Div. 1 / Groups ABCD
DUST IGNITION PROOF
DIP Class II, III / Div. 1 / Groups EFG- Install per National Electrical Code (NFPA 70)- Seal all conduits within 18 inches.
- All conduits must be assembled with a minimum of five full threads engagement.
- Temperature sensor assembly must be FM approved for appropriate area classification.
- Class II use a dust tight seal- Keep tight when circuits alive- U £ 35 V DC

Intrinsic safety barrier not required. Vmax £ 35 V DC.

Warning:

Do not disconnect equipment unless power has been switched off or the area is known to be non hazardous.

Nonincendive field wiring installation
The Nonincendive Field Wiring Circuit Concept allows interconnection of Nonincendive Field Wiring Apparatus with AssociatedNonincendive Field Wiring Apparatus or Associated Apparatus not specifically examined in combination as a system using any of thewiring methods permitted for unclassified locations.
Nonincendive Field Wiring parameters are as follows:
