Safety Warnings & Usage Precautions

Safety Warnings

1. This fan is a high-voltage device; no non-professionals may maintain/disassemble it when energized.

2. Only the company’s technical team is authorized to disassemble or modify the fan.

3. Sunlight shall not be liable for any injury/damage caused by non-compliance with the above rules.

Usage Precautions

1. Grounding: Motor aluminum housing must be grounded with M4 screw (1–1.2 Nm torque), grounding cable ≥1.5 mm² cross-section; connect to vehicle/equipment chassis ground.

2. High-voltage socket protection: No waterproof function without mating plug; avoid upward/dripping placement when vertical, keep socket on side/bottom.

3. Guard fixing: Use M10 hexagon socket screws with spring/flat washers, tighten to 10–12 Nm.

4. High-voltage power port: Pre-charge on power-on (10uF/1000V capacitor); keep continuously powered, control fan via low-voltage digital signals (no frequent on/off).

5. Fuse protection: Comply with ISO 8820 Part 3, use 15A fuse for single fan (rating adjustable by application scenario).

6. HVIL loop: Ensure normal connection; loop status is reported to upper controller via CAN bus and isolated from other circuits.

FAQ

1. What is the rated voltage and operating voltage range of the WBLF-2202-HS14200 fan?

   The nominal rated voltage is 600V DC, the operating voltage range is 400V-750V DC, and a voltage of ≥550V DC is required to reach the rated maximum speed.
2. What speed regulation methods does this fan support?

   It supports two modes: PWM digital signal speed regulation (10-1000Hz, recommended 400-600Hz) and CAN bus communication speed regulation (250/500kbps), with customizable CAN receive/transmit IDs.
3. What are the key grounding requirements for safe fan operation?

   The motor aluminum housing must be grounded with an M4 screw (tightening torque 1–1.2 Nm), the grounding cable cross-sectional area ≥1.5 mm², and the fan must be connected to the vehicle/equipment chassis ground.
4. What environmental conditions is the fan suitable for?

   It has an operating temperature range of -40~+85℃, a storage temperature range of -40~+110℃, and the controller has an IP67 protection rating; speed reduction triggers at 85℃, with a maximum temperature tolerance of 100℃.
5. Who is authorized to maintain or disassemble the fan?

   This is a high-voltage device: non-professionals are forbidden to maintain/disassemble it when energized, and only the company’s technical team is authorized to disassemble or modify the fan.
