DANGER
Danger due to bursting of the coupling
There is a risk of fatal injury from flying fragments. Bursting of the coupling can lead to an
explosion in potentially explosive atmospheres.
• Switch off the unit at once if any malfunctions occur.
• Note during the maintenance work the possible causes of faults and the notes on recti-
fying them.
Proceed as described below if there is a malfunction of the coupling during operation:
1. De-energise the drive immediately.
2. Initiate the required action for repair, taking into consideration the applicable safety regu-
lations.
If you cannot determine the cause or if you cannot carry out repair work with your own
means, request one of our customer service technicians.
7.2.2 Identifying the fault cause

Faults occur frequently due to application errors or they occur due to operational circum-
stances such as wear of wearing parts or changes to the system.
The faults and fault causes listed below only serve as an indication for troubleshooting. In
the case of a complex system be sure to include all the system components in the search for
the fault.
