9.3.3 Replacing the Filter Electrolytic Capacitor
● Possible damage causes: poor input power supply, high ambient temperature,
frequent load jumping, and electrolyte aging
● Determination criteria: liquid leakage, protruded safety valve, and measurements
of electrostatic capacitance and insulation resistance
● Replacement: To avoid damage to other components inside the AC drive, contact
Inovance for replacing the filter electrolytic capacitor.
9.4 Storage and Warranty
Storage
To store the AC drive properly, observe the following:
● For storage, pack the AC drive with the original packing box provided by Inovance.
● Avoid exposing the AC drive to moisture, high temperature, or outdoor direct
sunlight for an extended period.
● The electrolytic capacitor will deteriorate after the AC drive is stored for a long
time. Therefore, energize the AC drive once for at least five hours every six months.
Use a regulator to increase the input voltage gradually to the rated value. For any
problem, contact Inovance.
Warranty
Free warranty only applies to the AC drive itself.
Inovance provides an 18‑month free warranty to the equipment from the date of
manufacturing (subject to the barcode on the AC drive or contract if any) for failures
