Intrinsic Safety Explosion Protection of EAC Ex
A
2BN5D base plate for barrier
A2BN5D base plate for barrier 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 33J01A10-01EN “Integrated Production Control System CENTUM VP System
Overview”.
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 A2BN5D, take notice 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 A2BN5D for the parameter
of Intrinsic Safety.
