CARE, MAINTENANCE AND REPAIR
In order to ensure the long-term, proper functioning of the device, it must be regularly cleaned
and, if necessary, maintained. The maintenance requirement depends on the intensity of use and
the environment in which it is used.
We generally recommend a visual inspection before each operation. Furthermore, we recommend
carrying out all the applicable maintenance measures specified below once every 500 operating
hours or, in the case of a lower intensity of use, at the latest after one year. Warranty claims may
be limited in the event of defects resulting from inadequate maintenance.
CARE (carried out by user)
WARNING!
Before carrying out any care or maintenance, the power supply – and, if
possible, all device connections – must be disconnected.
PLEASE NOTE!
Improper care can lead to impairment of the device or even its
destruction.
1. Housing surfaces must be cleaned with a clean, damp cloth. Make sure that no moisture can
penetrate the device.
2. Air inlets and outlets must be regularly cleaned of dust and dirt. If compressed air is used,
make sure that damage to the device is prevented (e.g. fans must be blocked in this case).
3. Lines and plug contacts must be cleaned regularly and dust and dirt must be removed.
4. In general, no cleaning agents or abrasive agents may be used, otherwise the surface finish
may be damaged.
5. Devices must generally be stored dry and protected from dust and dirt.
MAINTENANCE AND REPAIR (by qualified personnel only)
HAZARD!
There are live components in the device. Even after disconnecting the
mains connection, there may still be residual voltage in the device, for example, due
to charged capacitors.
PLEASE NOTE!
There are no user-serviceable assemblies in the device.
PLEASE NOTE!
Maintenance and repair work may only be carried out by qualified
specialist personnel authorised by the manufacturer. If in doubt, consult the manufac-
turer.
PLEASE NOTE!
Improperly performed maintenance work may affect warranty claims.
