Observe requirements EN 60439-0
– The protective conductor connection parts are designed for a minimum
cross-section of 4 mm
2 .
– When installing the external protective conductor connection, care
must be taken to ensure that the conductors are secured against
twisting and loosening. This is achieved by professionally and firmly
laying the protective conductors close to the enclosure body.
– Applying a torque of 10 Nm to the screw connection ensures sufficient
contact pressure in conjunction with the enclosed spring washer.
– The choice of materials for the protective conductor connection is such
that electrochemical corrosion is not to be expected. Protective
conductors must be adequately protected against mechanical,
electrodynamic and thermodynamic influences and forces.
– Mechanical connections of protective conductors must be accessible
for inspection and testing.

Lead bushings through the enclosure wall on the ATEX enclosure
In order to be able to connect the DetCon-detonation controller to other devices, the leads must
be conducted through openings in the enclosure wall. This is possible in the form of screw
connections.
