The clearance and creepage distances between the bare, conductive parts of connection
terminals of separated, intrinsically safe circuits to earthed or potential-free, conductive
parts must be equal or greater than the values of IEC/EN 60079-11, Table 5.
If separated, intrinsically safe circuits have to be considered, the safety distance between
the blank, conductive parts of the outer connections must be as follows:
- at least 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
7.4 Mounting and Operating Position
7.5 Electrical Connection
- The conductor connection must be made with particular care.
- The conductor insulation must reach to the clamping points.
- Do not damage the conductor (nicking) when removing the insulation.
- Ensure that the maximum permissible conductor temperatures and the maximum
permissible surface temperature are not exceeded by performing a suitable selection
of electric lines and means of running them.
NOTICE

 When explosion-protected electric equipment is exposed to the weather,
it is advisable to provide a protective roof or wall.
WARNING
Ensure correct conductor connection!
 Observe the information regarding the connection cross-sections given in
chapter "Technical Data".
For cable entries ≤ M20 made of plastic special measures are required.
Please refer to the operating instructions of the cable entries for further
information.
