Installation, operating and maintenance instructions
DVN...D.F4
12.5. Electrical connection / wiring diagram
The device must be connected according to the wiring diagram. For fans which are controlled by external control de-
vices, the corresponding operating instructions of the manufacturer must be observed.

Delta circuit
12.6. Star circuit / Delta circuit
For the star circuit, the terminals U2, V2 and W2 are
connected through the shorting blades (see Img.).
Never connect both jumpers at the same time!
The star circuit must be used if the motor is to be ope-
rated directly on the 3-phase supply network with a
line voltage of 400V.
The star circuit is also to be used when controlling via a
frequency inverter with 400V output voltage (usually a
frequency converter with 3-phase 400V mains connec-
tion).
For the delta circuit, the shorting blades are connecting
U1 with W2, V1 with U2 and W1 with V2 (see Img.).
Never connect both jumpers at the same time!
The delta circuit must be used if the motor is to be ope-
rated directly on the 3-phase supply network with a
line voltage of 230V.
The star circuit is also to be used when controlling via
a frequency inverter with 230V output voltage (in ge-
neral frequency converter with 1-phase 230V mains
connection).
If, in spite of the correct connection to the mains or to the frequency converter, the devices turn contrary
to the given direction of rotation, this must be corrected. For this purpose two phases can be interch-
anged at the terminal block (e.g. L1 with L2 or L2 with L3). Afterwards the direction of rotation is to be
checked again.
For the electrical connection, for the setting of the motor protection switch or for the parameterization
of a frequency inverter, only the technical data on the nameplate of the fan are relevant. These may differ
from the technical data of the motor.
