2.4 General warning notices
M3560-02en Edition 09/2022 19
• If you want to use a coated coupling in potentially explosive atmospheres, please note
the requirements concerning the conductivity of the paint and the limitation on the paint
layer thickness applied in accordance with EN80079-36. No build-up of electrostatic
charges is to be expected with a paint layer thickness of less than 200μm.

DANGER
Danger due to bursting of the coupling
The coupling may burst if it is not used properly. There is a risk of fatal injury from flying
fragments. Personal injury, property damage and fire damage caused by sparks may oc-
cur. If a coupling bursts in an area at risk of explosion, then this can result in an explosion.
• Use the coupling for the purpose for which it is intended.
DANGER
Risk of explosion when using coupling parts without Ex marking
Coupling parts without Ex marking have not been approved for use in potentially explosive
atmospheres. These coupling parts can lead to an explosion during operation.
• Only use couplings with Ex marking in potentially explosive atmospheres.
DANGER
Danger
Risk of injury due to the use of unsuitable and/or damaged components. The use of unsuit-
able and/or damaged components can lead to an explosion in potentially explosive atmo-
spheres.
• Observe the information regarding conditions of use.
DANGER
Danger of explosion
Improper operation of the coupling can lead to an explosion in potentially explosive atmo-
spheres.
• Please observe the notes concerning operation of the coupling in potentially explosive
atmospheres.
DANGER
Danger from hot coupling parts
Risk of injury due to hot surfaces. Hot coupling parts can lead to an explosion in potentially
explosive atmospheres.
• Wear suitable protective equipment (gloves, safety glasses).
• Ensure that the area is not at risk of explosion.
