3. Sélection & 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°C) conditions

Replacement after inverter cooling fan failure

When SK-R1-FAN2-F8 is Recommended

Local hot spots inside the drive

High altitude (>1000m) or enclosed cabinet installation

Need to improve internal airflow for better overall cooling efficiency

Notes d'installation

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 mois)
