Intrinsic Safety Explosion Protection of EAC Ex
Base plate for barrier (S2BN5D)
Base plate for barrier (S2BN5D) is complied with I. S. explosion protection standard. P+F’s I. S.
barriers can be connected to the I. S. equipment installed in the hazardous area with explosion
proof wiring.
Explosion-proof specifications and Complied standard
Regarding the latest conformity standard, explosion-proof specifications and compliant products,
refer to the GS 32P01B60-01EN “Standards Compliant Models”.
Wiring of Intrinsic Safety Explosion Protection
An intrinsic safety circuit must be isolated from non-intrinsic safety circuit. Wiring should be
prepared in accordance with ГОСТ IEC 60079-14, or the standard of the country and the area in
which it is set.
In regards to the further wiring than the base plate for barrier (S2BN5D), takenotice that it should
be an intrinsic safety circuit. The wiring in cabinet should keep the distance to non-intrinsic safety
circuit.
After setting, check the wiring according to the checklist described in ГОСТ IEC 60079-14.
Parameter of Intrinsic Safety
Please refer to the P+F’s instruction manual of I.S. barriers installed in the base plate for barrier
(S2BN5D) for the parameter of Intrinsic Safety.
