ENTITY CONCEPT APPROVAL The Entity concept allows interconnection of intrinsically safe apparatus to associated apparatus not specifically examined in combination as a system. The approved values of max. open circuit voltage (Voc or Vt) and max. short circuit current (Isc or It) and max. power (Voc x Isc / 4) or (Vt x It / 4), for the associated apparatus must be less than or equal to the maximum safe input voltage ( Vmax), maximum safe input current (Imax), and maximum safe input power (Pmax) of the intrinsically safe apparatus. In addition, the approved max. allowable connected capacitance (Ca or Co) of the associated apparatus must be greater than the sum of the interconnecting cable capacitance and the unprotected internal capacitance (Ci) of the intrinsically safe apparatus, and the the approved max. allowable connected inductance (La or Lo) of the associated apparatus must be greater than the sum of the interconnecting cable inductance and the unprotected internal inductance (Li) of the intrinsically safe apparatus. Notes: 1. No revision to this drawing without prior Factory Mutual approval. 2. Associated apparatus manufacturer's installation drawing muste be followed when
installing this product.
3. Dust-Tigth seal must be used when installed in Class II and Class III environments. 4. Control equipment connected to the barrier must not use or generate more than 250 Vrms or Vdc. 5. Resistance between Intrinsically Safe Ground and Earth Ground must be less than 1.0 ohm. 6. Installations should be in accordance with ANSI/ISA-RP12.6 "Installation of Intrinsically Safe
Systems for Hazardous Locations" and the National Electric Code (ANSI/NFPA 70).
7. The associated apparatus must be Factory Mutual Approved.
WARNING : To prevent ignition of flammable or combustible atmospheres,read , understand and adhere to the
manufacturer's live maintenance procedures.
WARNING: Substitution of components may impair Intrinsic Safety.
