Part 5: Maintenance:
IMPORTANT NOTE: Disconnect the device from the power supply before servicing!
Screws used must be tightened and may not show rust marks. The housing, the mounting bracket and the
mounting location (e.g., ceiling or traverse) may not be adapted, e.g. do not drill additional holes in mounting
brackets, change the connections, etc.
Clean the externally accessible optical lenses regularly to optimize the light output. The frequency of cleaning
depends on the operating environment: damp, smoky or particularly dirty environments can cause a greater
amount of dirt accumulation on the device's appearance.
Use a lint-free, moistened cloth for cleaning. Never use alcohol or solvents for cleaning!
Change of fuse.
IMPORTANT: Replace the fuse only with a fuse of the same type and with the same values (printed on the unit). If
the fuse is triggered repeatedly, please contact an authorized service center.

2: Open the fuse holder on the back of the unit with a suitable screwdriver.
3: Remove the defective fuse from the fuse holder.
4: Insert the new fuse into the fuse holder.

Maintenance and service are reserved for the authorized personnel only!
