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 the deposition of
heavy metal oxides (rust) on the coupling is not possible.
In order to ensure safe commissioning, carry out various tests prior to commissioning.
Testing before commissioning
DANGER
Danger
Overload conditions can occur during the commissioning of the coupling. The coupling can
burst and metal parts can be flung out. There is a risk of fatal injury from flying fragments.
Bursting of the coupling can lead to an explosion in potentially explosive atmospheres.
• Carry out the tests prior to commissioning.
• Do not touch the rotating coupling.
1. Check the tightening torques of the screws of the coupling in accordance with
section Tightening torques and widths A/F (Page 58).
2. Check the tightening torques of the foundation bolts of the coupled machines.
3. Check whether suitable enclosures (ignition protection, coupling guard, touch protection)
have been installed and that the function of the coupling has not been adversely affected by
the enclosure. This also applies to test runs and rotational direction checks.
