Integrate maintenance plans directly into your work orders in MaintainX.

1 Yearly Inverter Inspection

Warning: This inspection requires trained personnel with PPE!

Manufacturing date of the inverter

If the inverter is stocked (not being used): Reforming

Enter the power applied to the inverter (voltage between 220 and 230 Vac, single-phase or three-phase, 50 or 60 Hz)

Apply power to the inverter for at least one hour

Then, disconnect the power supply and wait at least 24 hours before using the inverter (reapply power)

Sign off on the inverter inspection

Run this procedure

10 Yearly Electrolytic Capacitors Replacement

- If the inverter is stocked (not being used) make electrolytic capacitors “Reforming”

Every year from the manufacturing date printed on the inverter identification label (refer to section 2.4).

Apply power to the inverter (voltage between 220 and 230 Vac, single-phase or three-phase, 50 or 60 Hz) for at least one hour.

Then disconnect the power supply and wait at least 24 hours before using the inverter again (reapply power).

- If inverter in operation replace electrolytic capacitors every 10 years.

Contact WEG technical support to obtain the replacement procedures.;
