Notes
1. The Entity Concept allows interconnection of non-incendive apparatus with associated apparatus not specifically
examined in combination as a system when the approved values of Voc (or Uo) and Isc (or Io) for the associated
apparatus are less than or equal to Vmax (Ui) and Imax(Ii) for the non-incendive apparatus and the approved values of
Ca(Co) and La(Lo) for the associated apparatus are greater than Ci + Ccable and Li + Lcable, respectively, for the non-
incendive apparatus,
Where Ccable= 60pF/ft if unknown
Where Lcable= 0.20uH/ft if unknown
2. Simple apparatus: an electrical component or combination of components of simple construction with well-defined
electrical parameters that does not generate more than 1.5 V, 100mA, 25mW, or is a passive component that does not
disipate more than 1.3W and is compatible with the intrinsic safety of the circuit in which it is used.
3. Wiring methods must be in accordance with all applicable installation requirements of the county in use. For US, this is
NFPA 70 (NEC) article 504 with additional information in ANSI-ISA –RP12.06.01. For Canada this is CSA 22.1-12 (CEC)
section 18 and appendix F.
