of the control circuit. The high voltage test need not be performed again because it has been completed before

7.1.3 Replacement of Vulnerable Components
The vulnerable components of the AC drive are cooling fan and filter electrolytic capacitor.
Their service life is related to the operating environment and maintenance status. Generally, the service life is
shown as follows:
7.1.4 Storage of the AC Drive
For storage of the AC drive, pay attention to the following two aspects:
1) Pack the AC drive with the original packing box provided by HNC Electric.
2) Long-term storage degrades the electrolytic capacitor. Thus, the AC drive must be energized once every
2 years, each time lasting at least 5 hours. The input voltage must be increased slowly to the rated value with
the regulator.
7.2 Warranty Agreement
1) Free warranty only applies to the AC drive itself.
2) HNC Electric 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 AC drive for non-recommended function
