1) Short test run after connection of the mains voltage or control voltage
2) In case of overload of the frequency inverter, the speed of the fan is increased to 100 % regardless of the actual temperature of the device.
3) The fans switch on sequentially (interval approx. 1.8 sec)
4)
Maximum permissible mains overload current
