Troubleshooting and Maintenance
ATTENTION!
The electronic boards have electrostatic discharge sensitive components.
Do not touch the components or connectors directly. If necessary, first touch the
grounded metallic frame or wear a ground strap.
Do not perform any withstand voltage test: if necessary, consult WEG.
The inverters require low maintenance when properly installed and operated.
Table 6.2 on page 36
presents the main procedures and time intervals for preventive maintenance.

Replacement
Apply power to the inverter (voltage between

section
at least one hour. Then, disconnect the power
supply and wait at least 24 hours before using
