Service is charged according to the actual expenses , however , if there is contract , priority is given
The user must be familiar with the technical requirements for adjustable speed induction
motor drives , application and load characteristics before sellecting the inverters , and consider
the motor , output voltage and rated output current so as to select the correct model and operation
mode .The basic rule: Motor
s rated load current cannot exceed the rated current of the inverter.
’
Generally , Inverter’s overload capability is very important for the start and brake processes
according to the motor capacity. Please select the inverter with higher overload capability if short
time overload condition may occur or the application requires higher speed accuracy .

test , the input voltage must be boosted gradually with voltage regulator to the rated value .
The warranty is only confined to the inverter
Chapter 2 Product Information
