CAUTION
Continuous noise up to 60dBA during operation. Keep cabinet
doors closed during operation. To reduce inconvenience, we sug-
gest to use ear protection if cabinet doors must be opened during
normal operation.
The device shuts down in case of excessively high temperature
in the control cabinet. Make sure sufficient forced ventilation is
