Replacing the LCL filter moduleReplace the LCL filter module in the same way as the drive module.CapacitorsThe DC circuit of the power modules of the drive contain several electrolytic capacitors.Their lifespan depends on the operating time of the drive, loading and ambient temperature.Capacitor life can be prolonged by lowering the ambient temperature.Capacitor failure is usually followed by damage to the unit and an input cable fuse failure,or a fault trip. If you think that any capacitors in the drive have failed, contact ABB.■ Reforming the capacitorsThe capacitors must be reformed if the drive has not been powered (either in storage orunused) for a year or more. The manufacturing date is on the type designation label. Forinformation on reforming the capacitors, see Converter module capacitor reforminginstructions (3BFE64059629 [English]) in the ABB Library (https://library.abb.com/en).Control panelFor detailed information on the control panel, see ACx-AP-x assistant control panels user’smanual (3AUA0000085685 [English]).■ Cleaning the control panelUse a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratchthe display window.■ Replacing the control panel batteryFor instructions on how to replace the control panel battery, see the separate ACx-AP-xassistant control panels user’s manual document (3AUA0000085685 [English]).104 Maintenance
