that it is energized once within one year and the energized time is not less than 1 hour. The
input voltage must be slowly increased to the rated value with a voltage regulator.
8.2 Warranty Agreement
1) Free warranty only applies to the frequency inverter itself.
2) Shenzhen SCOV will provide 18-month warranty (starting from the leave-factory date as
indicated on the barcode) for the failure or damage under normal use conditions. If the
equipment has been used for over 18 months, reasonable repair expenses will be charged.
3) Reasonable repair expenses will be charged for the damages due to the following causes:
Improper operation without following the instructions.
Fire, flood or abnormal voltage.
Using the inverter for non-recommended function
4) The maintenance fee is charged according to SCOV's uniform standard. If there is an
agreement, the agreement prevails.
8.3 Faults and Solutions
SV600 inverter has many protective functions. When fault or failure occurs during operation,
the inverter will perform protective function and the keyboard will display the fault code. Please
refer to the table below for details of the fault types and common solutions. Please do not repair
or modify without authorization. If you cannot make troubleshoot, please contact our agent or
our company for supports.
