During the examination, not allowed to dismantle or rock a component for
no reason, even pull off a connector assembly. Otherwise, it can not run or
enter malfunction display state. And it will bring faults of the component,even
damage the host switch component IGBT module.
When needing measurement, user should pay attention to various different
meters which may reach very different measurement results. Pointer voltmeter
is recommended to use to measure input voltage. Rectifier voltmeter is
recommended to use to measure output voltage. Pliers galvanometer is
recommended to use to measure input and output current. And electrodynamics
wattmeter is recommended to use to measure power.

9.2 Components needed periodic replace

In order to guarantee the frequency inverter stable operation, except for
periodic maintenance, the inner component which bears long-term mechanical
wear should be periodic replaced---including the cooling fan、 main circuit
filter capacitor for energy caching and exchange、printed circuit board. In
general continuous using, users can replace them according to below regulation.
Also should according to the concrete conditions such as the usage environment、
load condition and frequency inverter current situation.
