9.3.2. Fans
The lifetime of the fans used to cool the power parts is dependent on usage and environmental conditions (temperature, dust).
Preventive replacement by an authorised technician is recommended within four years (in normal operating conditions).
When necessary fans should be replaced as per specifications by SOCOMEC.
9.3.3. Capacitors
The equipment houses electrolytic capacitors (used in the rectifier and inverter section) and filtering capacitors (used in the output
section), the lifetime of which is dependent on usage and environmental conditions.
The average expected lifetime of these components is shown below:
• Electrolytic capacitors: 5 years;
• Filtering capacitors: 7 years.
Component status is however verified during preventive maintenance.
