Maintenance
Periodically check the technical safety of the device, e.g. check for damage to the power cable
or the housing.
If you have a reason to believe that the device can no longer be operated safely, disconnect it
immediately and secure it against being operated unintentionally. Pull the power plug out of
the socket outlet!
It can be assumed that safe operation is no longer possible if:
› there is visible damage to the device or to the power line,
› the device no longer works,
› it has been stored for a long time under unfavourable conditions,
› it was exposed to extraordinary stress caused by transport.
Always observe the following safety instructions before cleaning or servicing the device:
Live components may be exposed if the covering is opened or components are re-
moved.
Prior to start of maintenance or repair works, the device must be disconnected from
all voltage sources.
Capacitors inside the device may still carry voltage even though they have been dis-
connected from all voltage sources.
Repairs may only be carried out by qualified personnel who are familiar with the
hazards involved and the relevant regulations.

Cleaning

The outside of the device should only be cleaned with a soft dry cloth or a soft brush. Never use
aggressive cleansing agents or solvents since these may damage the surface of the housing or
impair its operation.
