Functional ratings
-
FM
Approved
Apparatus must be installed in accordance with manufacturer 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.
-
Installation should be in accordance with
ANSI/IS
A R
P 12.6.01 “Installation of Intrinsically safe
systems for Hazardous (classified) locations” and the National
Electrical Code (ANSI/NFP
A 70).
