CARE, MAINTENANCE, AND REPAIR
The device must be maintained and serviced regularly, at least every 3,000 operating hours or
at the latest after one year, in order to ensure that it continues to operate properly over the long
term.
CARE (user executable)
WARNING! The power supply and, if possible, all device connections must be
disconnected before carrying out any care/maintenance measures.
NOTE! Improper care can lead to damage to the device or even destruction.
1. Housing surfaces must be cleaned with a clean, damp cloth. Make sure that no moisture can
penetrate the device.
2. Dust and dirt must be regularly removed from air inlets and outlets. If compressed air is used,
care must be taken to prevent damage to the device (e.g., fans must be blocked in this case;
otherwise they might overwind).
3. Cables and plug-in contacts must be cleaned regularly and dust and dirt must be removed.
4. In general, no cleaning agents or abrasive agents may be used to care for the device as this
could have a negative impact on the surface finish.
5. In general, devices must be stored in a dry place and protected from dust and dirt.
6. All accessible or removable lenses and light emitting apertures must be cleaned on a regular
basis to ensure proper and safe operation.
