 Danger!
When the fan is externally supplied with voltage, the terminal L2
carries dangerous mains voltage!
When the controller is supplied via the DC bus, the fan must be separately
supplied with mains voltage (see ). In this case, the bridge between the
terminals 102 and 103 must be removed (see ).
