Clearance and creepage distances of intrinsically safe components

Make sure that the creepage distances and clearances between the uncoated,
conductive parts of connection terminals of separated, intrinsically safe circuits to earthed
or potential-free, conductive parts is equal or greater than the values of EN IEC 60079-11,
Table 5.

For separated, intrinsically safe electric circuits, set up a safe distance between the
uncoated, conductive parts of external connections, which meets the following
requirements:
• Minimum 6 mm between the separated, intrinsically safe circuits
• At least 3 mm to earthed parts if a possible connection to earth has not been considered
in the safety analysis.
7 Commissioning
