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.
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. 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 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 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.
