——————————————————————————————————————————————— WARNING! The converters of the DCD300 series are running at high voltages. Even after disconnecting the converter, the capacitor circuits are still under voltage for a short period of time. Therefore it is absolutely recommended to wait 5 minutes until operating on the inner part of the converter.

The DISPLAY shows "6" when starting or during normal operation If this alarm occurs, cut off immediately the power supply of the DCD300 unit or better of the complete electrical installation and check the motor connections. If the connections result correct, check the condition of the brushes and if the motor is clean and free of carbon residues.
