Maintenance
Periodically verify the technical safety of the device, e.g. check for damage to the power cable or the housing.
If you have any reason to believe that the device can no longer be operated safely, disconnect it immediately and
make sure it is not unintentionally operated. Pull the power plug out of the power socket!
It can be assumed that safe operation is no longer possible if:
•
the device shows visible damage
•
the device no longer functions
•
the device has been stored for a long time under unfavourable conditions or
•
after exposure to heavy stress during transport
Always observe the following safety instructions before cleaning or servicing the device:
Live components may be exposed if covers are opened or components are removed.
The device must be disconnected from all power sources before carrying out any servicing or
repair work.
Capacitors inside the device may still carry voltage even though they have been disconnected
from all power sources.
Only qualified experts familiar with the hazards involved and the relevant regulations may
perform repairs.
Cleaning
The outside of the device should only be cleaned with a soft, dry cloth or brush.
Never use aggressive cleaning agents or chemical solutions as these may damage the surface of the casing.
