Standard replacement cycles of principal parts
As guides, the table below lists part replacement cycles that were estimated based on the assumption that
the inverter would be used in a normal use environment under normal conditions (ambient temperature,
ventilation conditions, and energizing time). The replacement cycle of each part does not mean its service
life but the number of years over which its failure rate does not increase significantly.
Also, make use of the life alarm function.
Note 1: The replacement cycle is calculated on the assumption that the average ambient temperature over
Note 2: Figures are for when the inverter output current is 80% of the rated current of the inverter.
Note 3: The life of parts varies greatly depending on the operating environment.
14.3 Making a call for servicing
If defective conditions are encountered, please contact your Toshiba distributor.
When making a call for servicing, please inform us of the contents of the rating label on the right panel of the
inverter, the presence or absence of optional devices, etc., in addition to the details of the failure.
14.4 Keeping the inverter in storage
Take the following precautions when keeping the inverter in storage temporarily or for a long period of time.
1.
Store the inverter in a well-ventilated place away from heat, damp, dust and metal powder.
2.
If no power is supplied to the inverter for a long time, the performance of its large-capacity electrolytic
capacitor declines.
When leaving the inverter unused for a long time, supply it with electricity once every two years, for 5 hours
or more each, to recover the performance of the large-capacity electrolytic capacitor. And also check the
function of the inverter. It is advisable not to supply the commercial power directly to the inverter but to
gradually increase the power supply voltage with a transformer, etc.
