8. TROUBLESHOOTING
8.3.2. Fans
The lifetime of 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).
Fans must be replaced by SOCOMEC technicians when required.
8.3.3. Capacitors
The equipment houses electrolytic capacitors (used in the rectifi er and inverter section) and fi ltering capacitors (used in the output
section), whose lifetime 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.
The actual condition of components is verifi ed during preventive maintenance.
