14.3 Making a call for servicing
For the Toshiba service network, refer to the back cover of this instruction manual. If defective conditions are
encountered, please contact the Toshiba service section in charge via your Toshiba dealer.
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.
(storage temperature:-25~+70°C)
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.
