296.4 Component ReplacementWear-out faults are related to endurance period and service life. The endurance periodlargely depends on the working conditions.1. For example, service life of relay is determined by the roughness of the contactsurface. Contact current and load inductance are the major factors affecting its servicelife.2.Capacitor inside the inverter is used mainly as a smoothing filter. Due to thechemical reaction that takes place internally, its service life is greatly affected by thetemperature. Generally speaking, rising of 10℃ in temperature reduces the servicelife of an aluminum electrolytic capacitor by half, which also affects the service life ofinverter. When the inverter is used under high temperature, the aluminum electrolyticcapacitor may suffer from wear-out faults prior to other components in normal statusand must be replaced to extend the service life of inverter.ComponentNameStandardreplacementinterval (year)Method of replacement/OthersCooling fan 5 years Replace with a new oneSmoothingcapacitor5 years Investigate and replace with anew one if necessary.Relays ― Investigate and replace with anew one if necessary.◆ Contact us for replacing or repairing the components.
