Chapter 11 Maintenance
11.1 Note
11.2 Storage and Transport
Conf irm the main circuit power supply has been turned off, and the
display has disappeared before carry out inspection and maintenance. Make
sure the system is in dynamic state, please pay attention to the following:
● Check whether the power supply voltage matches to the rated voltage
of the inverter;
● Check whether the motor makes unexpected noises or abnormal
vibration when running;
● Check whether there are abnormal heating;
● Check whether the inverter output voltage, output current, output
f requency, and monitor display is greater than the value commonly
used.
● Check whether the cooling fan installed at the lower part of the
inverter runs normally;
● Check whether the ambient temperature is too high and whether there
is dust, iron filings, corrosive fluid in the inverter;
● Check whether the ambient temperature of the inverter is between
-10
℃
~40
℃
, and whether the humidity is between 5%-85% (95% is
without condensation), phenomenon of water droplets is not allowed;
● The inverter should be discarded as industrial waste. It is forbidden to
burn it;
The inverter must be kept in its original package box before installation.
Pay attention to the followings when keeping it in storage if the inverter is not
used for the time being:
● It must be stored in a dry place without rubbish or dust;
● The suitable temperature for storage is between -25
℃
-65
℃
;
● The relative humidity required is 5%-95% without condensation;
● There is no corrosive gas or liquid in the storage ambience;
● It is better to lay the inverter on a rack and keep it in a proper package;
● The ambient temperature for transport is between -25
℃
-70
℃
;
● The relative humidity of transport ambience must be less than 95%
(Ambient temperature is 40
℃
).
Attention: It is better not to store the inverter for long time. Long time
storage of the inverter will lead to the deterioration of electrolytic capacity.
If it needs to be stored for a long time make sure to power it up one time
within a year and the power-up time should be at least above five hours. When
powering up, supply voltage must be increased slowly with a voltage regulator
to the rated voltage value.
