210 Maintenance
V560 Series High Performance Closed-Loop Vector Inverter User Manual
9.3 STORAGE
After purchase the frequency inverter, if the frequency inverter will be spared for a while or stored for a long
time, users shall pay attention to the following items:
1) Storage environment should comply with the following table:
Environmental
characteristics
Requirements Remarks
Ambient
temperature
-10 °C to 45 °C
Long-term storage temperature is no more than 45 °C, so
as to avoid the degradation of capacitance characteristics.
It shall avoid condensation and frozen environment
caused by sudden change of temperature.
Relative humidity 5 to 95%
It can adopt measurement like plastic film sealing and
desiccant.
Storage
environment
Free from direct sunlight, no dust,
no corrosive, no combustible gas,
no oil, no steam, no gas, no drip,
no vibration, and with little salt
2) If the frequency inverter is not in use for a long time, the current shall be applied to restore filter capacitor
characteristics every half year, and at the same time other features of the frequency converter shall also
be checked. W hen the current is applied, it shall increase the voltage gradually through autotransformer,
and the conduction time should be above half an hour.
9.4 WARRANTY
If the frequency inverter body has the following cases, the company will provide guarantee service:
1) If failures or damages occur in normal use within the warranty period (within 18 months from the date of
purchase), our company will provide free maintenance. Our company will charge a reasonable cost of
maintenance in case of more than 18 months above.
2) Even in the guarantee period, if any failure is caused by the following cases, our company will charge
some of the maintenance cost:
Malfunction due to that the users do not operate according to the operation manual or beyond the
standard;
Malfunction due to repair and modification without permission;
Malfunction caused by poor preservation;
Malfunction caused by improper use;
Damage to the machine due to fire, corrosive salt, gas corrosion, earthquake, storms, floods, thunder,
abnormal voltage or other force majeure.
3) The company will provide lifelong paid maintenance services even the warranty period expire.
¾ If the frequency inverter is not in use for a long time, the internal filter capacitance
characteristics would decline.
