AAFM Approved Apparatus must be installed in accordance with manufacturer’s instructions.
Use supply wires suitable for 5°C above surroundings.
Only simple apparatus should be terminated to the sensor connection.
Simple apparatus are components as defined by the NEC (1.2 V, 0.1 A, 0.25 mW or 20 µJ).
Warning: Substitution of components may impair intrinsic safety or suitability for Class I, Division 2.

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)- For Group A, seal all conduits within 18 inches of enclosure; otherwise, conduit seal not required forcompliance with NEC 501.5(A)(1)(1).
- 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
