10. Maintenance and repair
10.1 Maintenance in the case of domestic use
For long-lasting and safe operation we recommend that
you have a qualified electrician inspect the device for proper
condition at regular intervals.
10.2 Maintenance in the case of industrial use
When using the device in an industrial environment, the
operator / user of the device must have a qualified electrician
check the device for proper condition at regular intervals.
10.3 Maintenance tasks
The performance of regular inspection and maintenance
tasks supports trouble-free and safe operation of the device
and contributes to increasing its service life. Thus any fault
sources can be detected early on and hazards can be avo-
ided. We recommend that you visually inspect the device
for external damage (e.g. material alterations, missing com-
ponents, etc.) and its proper functioning (e.g. protective
elements) regularly.
If defects are detected on the device they must be rectified
without delay. A damaged, faulty device must not be used
because the risk of electric shock or material damage can
increase.
WARNING

due to electric shock
Take the power distribution box out of service for

Disconnect the plug of the supply line.
Simple maintenance tasks (e. g. visual inspection
