2.7 Instructions on Warranty of Inverter
Free warranty only applies to the inverter itself.
1、Our company will provide 12-month warranty (starting from the date of sale
) for the fault or damage under normal use conditions. If the equipment has been
used for over 12 months, reasonable repair expenses will be charged.
2、Reasonable repair expenses will be charged for the following situations within 12
months:
1) The equipment is damaged because the user fails to comply with the
requirements of the user’s manual;
2) Damage caused by fire, flood and abnormal voltage;
3) Damage caused when the inverter is used for abnormal function.
The service expenses will be calculated according to the standard of the
manufacturer. If there is any agreement, the agreement shall prevail.
2.8 Guide to Model Selection
When selecting inverter, firstly make clear the details regarding the technical
requirements for variable frequency speed adjustment of the system, applications of
inverter and load characteristics and take into overall consideration the adaptable
motor, output voltage, rated output and other factors, and then select the model
meeting your requirements and determine the running mode.
The basic principle is that the rated load current of the motor cannot exceed the rated
current of the inverter. Generally, the model is selected in accordance with the
capacity of the supporting motor as specified in the user’s manual, with attention to
the comparison of rated currents between
the motor and the inverter. The overload capacity of the inverter makes sense only
for the startup and brake processes. If instantaneous overload occurs in the running
process, the load speed will vary. If there are higher requirements for the speed
precision, please consider a larger one.
