Installation Notes
A
TT082
- FM
Approved
Apparatus must be installe
d in accordance with manufacture
r’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).
-
W
arning: Substitution of components may impair intrinsic safety or suitability for Class I, Division 2.

-
Install per National Electrical Code (NF

- For Group
A, seal all conduits within 18 inches of enclosure; otherwise, conduit seal not required for complia
nce with
NEC 501.5(A)(1)(1). -
All conduits must be assembled with a minimum of five full threads engagement.
-
T
emperature sensor assembly must be FM approved for appropriate area classification.
- Class II use a dust tight seal - Keep tight when circuits alive
NONINCENDIVE NI Class I / Di
