Chapter 8. Troubleshooting and Maintenance
8.3 Precautions for maintenance
Make sure to remove the input power while performing maintenance.
Make sure to perform maintenance after checking the DC link capacitor has
discharged. The bus capacitors in the inverter main circuit can still be charged
even after the power is turned off. Check the voltage between terminal P or P1
and N using a tester before proceeding.
SV-iE5 series inverter has ESD (Electrostatic Discharge) sensitive components.
Take protective measures against ESD before touching them for inspection or
installation.
Do not change any inner parts and connectors. Never modify the inverter.
8.4 Checklist
