Keeping The Inverter In Storage - Toshiba TOSVERT VF-S11 Instruction Manual

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 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.
