Box-s www.blaubergventilatoren.de MOUNTING AND SET-UP BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER). WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR. Prior to mounting the unit: Make sure that the fan impeller rotates freely.
Box-s www.blaubergventilatoren.de CONNECTION TO POWER MAINS DISCONNECT THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER CAREFUL READING OF THE PRESENT USER’S MANUAL.

Box-s www.blaubergventilatoren.de ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS There are several methods for starting asynchronous squirrel-cage electric motors. The most common methods are: direct-on-line (DOL), with a soft starter (SS) or with a frequency converter (FC). Direct-on-line starting In case of direct-on-line starting (i.e. by connecting the motor to the electric mains with a simple line contactor), the motor starting time significantly increases due to high inertia of the impeller, which, in turn, results in high in-rush starting currents in the circuit.
Box-s www.blaubergventilatoren.de Let us review three variations of a heavy start: 1. The feed line performance is barely sufficient or insufficient to maintain the induced current. Typical symptoms: Upon starting the circuit breakers at the system input are tripped; the lights, certain relays and contactors go off, and the supply generator shuts down.
Box-s www.blaubergventilatoren.de TECHNICAL MAINTENANCE DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS! ENSURE THAT THE UNIT IS SWITCHED OFF FROM THE SUPPLY MAINS BEFORE REMOVING THE GUARD. The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.
