–Clean air vents, page 45
–Check the connectors and grounding, page 45
!
Warning!
Dangerous mains voltages are present inside the 19" units. Disconnect the mains power
supply before you do any maintenance.
Clean the units
Periodically clean all units with a damp, lint-free cloth; never use water or chemicals.
Clean air vents
The multi channel DSP amplifier can collect dust as a result of the internal fan.
Base the interval on the actual situation and dust build‑up. Start with an interval of at least
once a year. Use a vacuum cleaner to clean the air vents of all units.
Check the connectors and grounding
Periodically check:
– All cable connections for corrosion and the screw terminals to make sure that they have
not become loosened.
– The ground (PE) connection of the system components.
