Electrical Connection

electrical-connection

PE	Green/Yellow	Protective earth
U1 / L	Brown	Power supply, live wire
U2 / N	Blue	Power supply, neutral wire
U4 / +10V	Red	External +10 VDC output
U5 / Speed Control	Yellow	0–10 V and PWM compatible input; maximum PWM amplitude 10 V
U6 / Signal Feedback	White	Speed-output signal
U7 / GND	Blue	Control-line ground

The fan provides a speed-output signal. Vfg and the pull-up resistor are supplied externally by the customer. Vfg = (3–30) VDC; R ≥ 1000 × (Vfg) Ω.

Notes

Connect the power and control lines strictly according to the wiring diagram to prevent fan damage.
Do not connect the white signal wire directly to the red signal wire or an external DC power supply.
If the fan does not operate after start-up, check the speed-control input voltage and connections. Do not touch the impeller or rotor after power is applied.
The fan may take several seconds to start. Do not touch the impeller or rotor when power is applied or during low-speed operation.
People without appropriate safety supervision, including children, must not use this product.
If the power cable is damaged, it must be replaced by the manufacturer.
The motor must not be operated without the impeller or a load.
For storage after unpacking, repack the product and store it in a clean, ventilated, non-corrosive environment at −40 °C to +80 °C, at no more than 95% relative humidity and at least 15 cm above the ground.
Read this technical specification carefully before use.
