The fan provides a speed output signal. Vfg and the pull-up resistor are connected by the customer. Vfg = (3.3–30) VDC; R ≥ 1000 × (Vfg) Ω.
Note
Connect the power line and control line strictly according to the wiring diagram.
Do not connect the white signal wire directly to the red signal wire or external DC power supply.
Check the speed-regulation input voltage if the fan does not operate after start; do not touch the impeller or rotor after energizing.
Allow a few seconds for the fan to start after power-on; do not touch rotating parts during power-on or low-speed operation.
Before switching on, confirm that the motor is installed reliably.
If the power cable is damaged, it must be replaced by the manufacturer.
Do not drop, strike or flush the motor.
Consult Blauberg before using specially customized products outside agreed operating conditions.
The motor casing may be hot after the fan stops; prevent burns if necessary.
Before operation, rotate the rotor by hand to confirm there is no collision or interference.
The motor must not be used alone without an impeller or load.
Store in a clean ventilated warehouse at -40°C to +80°C, max. 95% RH, free of corrosive gas and at least 15 cm above ground.
Keep this product out of reach of children.
