Replacement of expendable parts
Inverters include lifetime parts (aluminum electrolytic capacitors, cooling fans, etc.). These parts age
because of the configurations or the physical properties. If they are left unused for a long time, the
performance of the inverter will deteriorate, thus resulting in a failure. Be sure to perform periodical
inspection for preventive maintenance.
For replacement of each replacement part, contact your Toshiba distributor. Do not replace the parts on
your own for safety.
1) Cooling fan inspection
The inspection items for the cooling fans are as follows:
•
Are the cooling fans rotating stably?
•
Is any unusual sound or vibration found?
Estimated time of replacement of the cooling fans that cool down the heat-generating parts are 10
years.
* Average ambient temperature 40°C, relative humidity 65%, load factor 80%, 24-hour operation per day
However, do not have corrosive gas, oil mist, dust, metal powder and so on.
Also, replace the fans when unusual sound or vibration is found.
For replacement of the cooling fans, contact your Toshiba distributor.
2) Smoothing aluminum electrolytic capacitor inspection
The inspection items for the smoothing aluminum electrolytic capacitor are as follows:
•
Is liquid leak found?
•
Is the safety valve lifted?
Estimated time of replacement of the smoothing aluminum electrolytic capacitor is 10 years.
* Average ambient temperature 40°C, relative humidity 65%, load factor 80%, 24-hour operation per day
However, do not have corrosive gas, oil mist, dust, metal powder and so on.
The replacement of the smoothing aluminum electrolytic capacitor is replaced the inverter itself.
Contact your Toshiba distributor.
☆
You can check the parts replacement alarm and output signals in [Monitor mode].
For details,
refer to [6. 18. 14].
☆
Estimated timing of replacement of the smoothing aluminum electrolytic capacitor becomes shorter at
high ambient temperature, and becomes longer at low ambient temperature.
