Appendix G

Control Schematic for Wiring of Intrinsically safe SmartCal for ATEX &
IECEX

(Sheet 1 of 2)

Entity parameters for each field wiring terminal pair of SmartCal:

Vmax = 30V

Imax = 100mA Pi=0.75 Watt

Ci = 0 pF

Li = 17.25 uH

1. ATEX Entity approved associated apparatus used in an approved configuration, such that:

A. SmartCal Vmax



Voc and Vt of associated apparatus.

B. SmartCal Imax



Isc and It of associated apparatus.

C. Ci of SmartCal cable capacitance



Ca of associated apparatus.

2. Associated apparatus manufacturer’s installation drawing must be followed when installing

this equipment.

3. Control equipment connected to associated apparatus must not use or generate more than

250V.

4. To maintain intrinsic safety, each field wiring pair (4-20 mA and Analog Output) must be

run in separate cables or separate shields connected to intrinsically safe (Associated
Apparatus) ground.

5. Where rigid metal conduit is not used, seal SmartCal cable entries against dust and fibers

using an appropriate NRTL listed cable gland fitting.

6. Installation should be in accordance with EN 60079 and / or the local / national electrical

codes of practice.
