of the terminal base must be taken
into account to verify the intrinsic safety.
Simple apparatus is defined as a device which neither generates nor stores
more than 1.2V, 0.1 A, 20 μ J, or 25 mW.
Wiring methods must be in accordance with the National Electric Code,
ANSI/NFPA 70, Article 504 and 505 or the Canadian Electric Code CSA
C22.1, Part 1, Appendix F. For additional information refer to ANSI/ISA

This module, 1797-IE8, must be used with terminal base 1797-TB3 or
1797-TB3S.
Terminals 3, 7, 11, 15, 20, 24, 28, 32, 36-39, and 46 to 49 shall not be
connected.
WARNING : Substitution of components may impair intrinsic safety.
AVERTISSEMENT: La substitution de composant peut compromettre la
securite intrinseque.
