3. Выбор & Application Recommendations

When SK-R1-FAN1-F8 is Required

All newly installed Frame 8 drives

Drives operating under Heavy Duty (HD) or high ambient temperature (>40°С) conditions

Replacement after inverter cooling fan failure

When SK-R1-FAN2-F8 is Recommended

Local hot spots inside the drive

High altitude (>1000м) or enclosed cabinet installation

Need to improve internal airflow for better overall cooling efficiency

Примечания по установке

Both can be installed together for a complete “primary cooling + auxiliary airflow” solution

Installation must be performed by qualified technicians to ensure safe electrical and mechanical connections

Disconnect power and allow heat sinks to cool fully before replacement to avoid burns

Inspect fan operation and clean dust regularly (recommended every 6 месяцы)

4. Model Naming Convention

PowerFlex 750 cooling fan models follow a unified coding system:

5. Выбор & Руководство по применению
6. Primary cooling fan is mandatory: All new PowerFlex 750 drives must be equipped with the corresponding frame-matched SK-R1-FAN1-Fx (internal primary) or SK-R9-FAN11-Fx (external primary) fan.
7. Auxiliary cooling recommendation: For high ambient temperature (>40°С), high altitude (>1000м), or enclosed cabinet installations, add SK-R1-FAN2-Fx series stirring fans.
8. Protection rating matching: For outdoor or dusty environments, select SK-R9-FAN14-Fx-series NEMA 4X protected fans.
9. –Frame compatibility–: SK-R1-FAN1-F8 is compatible with Frame 8–10; all other models are frame-specific.
