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 main enance 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 inade-
quate maintenance.
CARE (CARRIED OUT BY THE USER)
WARNING! Before carrying out any maintenance work, the power supply and, if possible,
all device connections must be unplugged.
PLEASE NOTE! Improper care can lead to impairment of the device or even destruction.
1. Housing surfaces must be cleaned with a clean, damp cloth. In doing so, ensure that no moisture
can penetrate into the device.
2. Air inlets and outlets must be regularly cleaned of dust and dirt. If compressed air is used, care must
be taken to ensure that damage to the device is prevented (e.g. fans must be blocked in this case,
as they could otherwise over-rev).
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)
DANGER! There are live components in the device. Even after disconnecting the mains
connection, there may still be residual voltage in the device, e.g. due to charged capacitors.
PLEASE NOTE! There are no user-serviceable components in the device.
PLEASE NOTE! Maintenance and repair work may only be carried out by sufficiently qualified
specialist personnel. If in doubt, consult a specialist workshop.
PLEASE NOTE! Improperly performed maintenance work may affect warranty claims.
PLEASE NOTE! For conversion or retrofit sets provided by the manufacturer, it is essential to
observe the installation instructions included.
