Speed Control Settings
| Control Method | Operating Condition |
| Full speed | Short the red (+10 V) and yellow (speed-control) conductors. |
| 0–10 VDC | Motor starts above 1.0 V and stops below 0.5 V. |
| PWM | Frequency 1–10 kHz; recommended amplitude 10 V ±5%. Motor starts above 10% duty and stops below 5% duty. |
| Potentiometer | A 10 kΩ potentiometer is recommended. |
Note
| 1 | Connect the power and control conductors strictly according to the wiring diagram. |
| 2 | Do not connect the white signal-feedback conductor directly to the red conductor or to an external DC power supply. |
| 3 | Shorting the red and yellow conductors applies the fixed 10 V reference and commands full speed. |
| 4 | If the blower does not start, check the speed-control input. Prevent injury from an unexpected start and never touch the rotor while energised. |
| 5 | Startup may take several seconds. Do not touch the impeller or rotor while energised or operating at low speed. |
| 6 | Before applying power, verify that the motor and blower assembly are installed securely. |
| 7 | Do not pull the cable. A damaged cable must be replaced by the manufacturer or authorised service personnel. |
| 8 | Do not drop, strike or wash the motor; moisture can reduce insulation performance and create a safety hazard. |
| 9 | Consult the manufacturer before using the product outside the agreed operating conditions. |
| 10 | The motor casing may remain hot for a short time after shutdown. Take measures to prevent burns. |
| 11 | Keep the housing clean and prevent debris from entering during installation. |
| 12 | Before initial operation, rotate the rotor by hand to confirm that there is no collision, interference or jamming. |
| 13 | The motor is part of the blower and must not be operated alone without an impeller or load. |
| 14 | For storage after unpacking, repack the product and keep it at -40 to +80 °C, RH ≤95%, in a clean ventilated area free of corrosive gases and at least 15 cm above the floor. |
| 15 | Install the blower out of children's reach and do not allow children to operate it. |
| 16 | The manufacturer reserves final interpretation of this specification. |
Life and Maintenance, Warranty
| 1 | The design life is 50,000 hours, limited by ball-bearing life at 40 °C. Actual service life depends on temperature, humidity, installation, load and the operating environment. |
| 2 | Clean and maintain the blower every 3–6 months, adjusted as appropriate for the operating environment. |
| 3 | The complete product is covered by a two-year warranty from the delivery date. Product-quality failures will be repaired or replaced. Damage caused by unauthorised disassembly, improper handling, human action, natural disaster or other force majeure is excluded. |
