The nonincendive field wiring circuit concept allows interconnections of nonincendive
field wiring apparatus with associated nonincendive field wiring apparatus, using any of
the wiring methods permitted for unclassified locations.
Vmax ≥ Voc or Vt
Ca ≥ Ci + Ccable
La ≥ Li + Lcable
For this current controlled circuit the parameter Imax is not required and need not
be aligned with parameter Isc or It of the barrier or associated field wiring apparatus.
For guidance on installation see ANSI/ISA RP 12.06.01 "Installation of Intrinsically Safe
Instruments Systems for Hazardous (Classified) Locations".
Install in accordance with the National Electrical Code NFPA 70 for US jurisdictions.
Install in accordance with the Canadian Electrical Code C22.1-02 for Canada jurisdictions.
WARNING : Substitution of components may impair intrinsic safety. For installation,
maintenance, or operation instructions see instruction manual.
