Should a failure occurs, contact your Toshiba distributor. Before contact, check the information on the
name plate attached on the right side of the inverter unit, and presence or absence of the optional parts to
inform the distributor of them as well as inverter problems.
If you store the inverter temporarily or for a long time after purchase, follow the instructions below.
(1) Storage location
Store the inverter indoors. Avoid to be exposed to direct sunlight, corrosive, explosive or flam-
mable gases, salt, oil mist, dust, metal powder, vapor or condensation.
Storage temperature and Relative humidity are shown in the table below.
(2) Periodical check
If no power is supplied to the inverter for a long time, the performance of its main circuit
smoothing aluminum electrolytic capacitor declines.
When leaving the inverter unused for a long time, energize it for an hour or more each without
load in accordance with the table below, to recover the performance of the electrolytic capaci-
tor. Then check the function of the inverter.
