Note 4: The Entity Concept allows interconnection of intrinsically safe
apparatus with associated apparatus not specifically examined in
combination as a system when the approved values of Voc and
Isc for the associated apparatus are less than or equal to Vmax and

be left open at the field end and connected to chassis ground at the
Module end.
Note 2: Pins marked N/C are not electronically connected to the Module.
Imax for the intrinsically safe apparatus and the approved values of
Ca and La for the associated apparatus must be equal to or are
greater than Ci and Li for the intrinsically Safe apparatus plus all
cable parameters.
Ca ≥ Ci + Ccable; La ≥ Li + Lcable; Voc ≤ Vmax; Isc ≤ Imax
Note 5: Simple Apparatus is defined as a device which will neither generate
nor store more than 1.2V, 0.1A, 20uJ, or 25 mW. For examples
switches, Thermocouples, LEDs and RTDs, Etc.
Note 6: Wiring methods must be in accordance with National Electrical
Code NFPA 70, Article 504 and ANSI/ISA RP12.6, “Wiring Practices
for Hazardous (classified) Locations Instrumentation
Part I: Intrinsic Safety”.
Note 7: Control room equipment connected to associated apparatus
should not use or generate more than 250Vrms.
Note 8: All modules must be installed in an enclosure that meets the
requirements of ANSI/ISA S82.01
Note 9: No revision to this drawing without prior FMRC Approval.
