AC100 HIGH-PERFORMANCE VC INVERTER MANUAL
Check if it meets the requirement of
Surroundings
table3-1.
Check if the inverter or the motor heat or
Cooling system change color abnormally and cooling fan
working state.
Motor Check if there is abnormal vibration or noise.
Check if output current is over the rated
Load value of the motor or the inverter and has
lasted for a period.
No operation under power connecting state. Otherwise, there is danger of electric shock even death.
Before operating, please cut all related equipments power, ensuring that the main circuit DC current has
dropped to safe range. And please operate after 5 mins.
Regular Inspection
●
On normal cases, do one inspection every 3 or 4 months. Please decide the actual inspection period according to the
machine use condition and working circumstance when using the machine.
