14.3Making 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.

14.4Keeping 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 the printed circuit board in your inverter has an anti-static cover (black cover), do not leave it detached from the circuit board during storage, though the cover must be detached before turning on the inverter.

3.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 to 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.
