4. Intrinsic Safety Explosion Protection Instrumentation

4-2

TI 33Q01J30-01E

4.1 

Intrinsic Safety Explosion Protection 

Instrumentation Using Barrier base plates

I.S. barriers comply with the I.S. explosion protection standard and can be mounted on the base 
plate (A2BN4D) (*1) which are connected to the I.S. equipment installed in the hazardous area 
with explosion-proof wiring. As for the intrinsic safety explosion protection instrumentation, refer 
to the instruction manual of the I.S. barriers of MTL products.

*1:  

Refer to “Base Plates (for N-IO)” (GS 33J62F40-01EN) for more details.

4.1.1 

Intrinsic Safety Explosion Protection of ATEX/UKEX 

Standard

  A2BN5D base plate for barrier

A2BN5D base plate for barrier can be connected to the I.S. equipment installed in the hazardous 
area with explosion-proof wiring and can be installed in Zone 2 by mounting in a keyed metal 

cabinet with protection rating of IP54 or higher as shown in the following figures.  Please refer to 

the instruction manual of P+F I.S. barriers for installation of I.S. barriers.

Note:  Regarding the latest conformity standard, 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 EN 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 (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 EN 60079-17.

  Parameter of Intrinsic Safety

Please refer to the P+F’s instruction manual of I.S. barriers installed in the base plate for barrier 
(A2BN5D) for the parameter of Intrinsic Safety.
