apparatus and the approved values of C

and L

of the associated apparatus

are greater than C

+ C

cable

and L

+ L

cable

respectively for the intrinsically safe

apparatus. The internal capacitances of C

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 μJ, 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
