Note
Shutting down the device in the event of contaminated external heat sinks
For components with external air cooling, the fan and the heat sinks can accumulate a lot of
pollution. If the cooling air requirement is not provided by the filter fan, the co
mponents
cannot output their specified power. This can cause the temperature monitoring function in
the components to respond.
Check the fans and heat sinks for pollution at regular intervals and clean them when
necessary.
