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.
