Notes concerning operation of the coupling in potentially explosive atmospheres
• Only use the coupling 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.
• Parts of the coupling are manufactured out of aluminium. The coupling must therefore be
provided with stable housing that excludes the risk of ignition, e.g. due to friction, impact
or friction sparks.
DANGER
Danger due to igniting deposits
During use in potentially explosive atmospheres deposits from heavy metal oxides (rust)
can ignite due to friction, impact or friction sparks and lead to an explosion.
• Ensure through the use of an enclosure or other suitable measures that heavy metal
oxide (rust) deposits on the coupling are not possible.
• Ensure that the drive is switched off no later than 5 minutes after the fusible safety plug
(103) has responded.

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.
