CARE, MAINTENANCE AND REPAIR
In order to ensure the long-term, proper functioning of the device, it must be regularly cleaned and,
if necessary, serviced. The servicing requirement depends on the intensity of use and the environment
in which it is used.
We recommend a visual inspection before each operation. Furthermore, we recommend carrying out
all the applicable service 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 should defects
result from inadequate service and maintenance.
CARE (CARRIED OUT BY USER)
WARNING! Before carrying out any care and maintenance work, the power supply and,
if possible, all device connections must be disconnected.
NOTE! Improper care can lead to impairment or even destruction of the device.
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. Cables and connectors must be cleaned regularly and dust and dirt must be removed.
4. In general, no cleaning or disinfection agents or abrasive agents may be used, as they may damage
the surface finish. Solvents in particular, such as alcohol, can impair the function of housing seals.
5. Devices must generally be stored in a dry environment 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 assemblies in the device.
NOTE! Maintenance and repair work may only be carried out by specialist personnel
authorised by the manufacturer. If in doubt, consult the manufacturer.
PLEASE NOTE! Improperly performed maintenance work may affect warranty claims.
