Notes concerning operation of the coupling in potentially explosive atmospheres
• Only use the coupling underground in mines in potentially explosive atmospheres together
with drive motors that can be switched off in the event of the formation of an explosive
atmosphere.
• Earth machines that are connected via the coupling with a leakage resistance of less than
10
6
Ω.
• 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 EN 80079-36. No build-up of electrostatic charges is to
be expected with a paint layer thickness of less than 200 μm.
• The supplier of the assembly is responsible for ensuring that the brake system and all of its
components are designed in accordance with the relevant directive.
2.4 General warning notices
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. Bursting of the coupling can lead to an explosion in potentially explosive
atmospheres.
• 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.
