8.4 Storage and the Maintenance
8.4.1 Storage
After purchasing the frequency converter, users should pay attention to the following points
when storing it.
(1) When storing, please try to put the frequency converter in the original packaging box
according to the original packaging.
(2) Long-term storage will cause the deterioration of the electrolytic capacitor, and it must be
energized once within 2 years. The input voltage must be slowly increased to the rated value
with a voltage regulator. For details, please refer to chapter 3.1.1. It is generally recommended
to power on for more than 5 hours.
8.4.2 Maintenance
Under normal use, if the frequency converter fails or is damaged, the A-TS company is
responsible for a 12-months warranty (from the date of delivery, subject to the date displayed
on the bar code on the frequency converter body). If it has been more than 12 months, a
reasonable maintenance fee will be charged.
The warranty only covers the frequency converter itself.
Within 12 months, if the following situations occur, a certain maintenance fee shall be charged.
(1) The user did not follow the regulations in the manual, causing damage to the frequency
converter.
(2) Frequency converter damage caused by force majeure, including but not limited to fire,
flood, abnormal voltage, etc.
(3) Damage caused when the frequency converter is used for abnormal functions.
