2. Installation Notes

Install vertically with ≥100mm clearance above/below and ≥50mm left/right for ventilation

Avoid direct sunlight, heat sources, and strong vibration

Install ventilation fans in control cabinet to keep ambient temperature ≤40℃ (SLD)

2. Wiring Standards

Route main circuit and control circuit separately to reduce EMI

Use shielded power cables with single-point grounding of shielding layer

Keep braking resistor wiring short and thick to avoid voltage drop affecting braking performance

3. Maintenance Schedule

Daily inspection: Operating status, abnormal noise, vibration

Periodic maintenance:

Every 6 months: Clean heat sinks, check fan operation

Annually: Inspect capacitor performance, terminal tightening, insulation test

Every 3 years: Replace cooling fan and main circuit capacitors
