Chapter 6: Overhaul and Maintenance 

During frequency inverter normal operation, except for daily inspections, periodic (such as machine 

overhaul or inspections at least every six months as required) inspections must be performed according 

to the following table, to preven t trouble before it happens.

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.
