4) Capacitance and inductance of the field wiring from the nonincendive field wiring
apparatus equipment to the associated nonincendive field wiring apparatus shall
be calculated and must be included in the system calculation as shown in the
above table. Cable capacitance Ccable, plus nonincendive field wring apparatus
capacitance Ci, must be less than the marked capacitance Ca (or Co), shown on
any associated apparatus used. The same applies for inductance (Lcable Li and
La or Lo respectively). Where the cable capacitance and inductance per foot are
not known, the following values shall be used:
5) The associated apparatus must be connected to a suitable ground electrode per
the national Electrical code (ANSI/NFPA 70), the Canadian electrical code or
other local installation codes, as applicable the resistance of the ground path
must be less than 1 ohm.
6) Where multiple circuits extend from the same piece of associated apparatus,
they must be installed in separate cables or in one cable having suitable
insulation. Refer to article 504.30 (B) of the National Electrical code (NFPA 70)
and Instrument Society of America Recommended Practice ISA RP12.6 for
installing intrinsically safe equipment.
7) This associated apparatus has not been evaluated for use in combination with
other associated apparatus.
