Avoid installing the inverter in a hot,
damp, or dusty place, a place subject
to freezing or water splash, or a place
full of metal chips.
Do not install the inverter where there
are gases that corrode metal or
solvents that adversely affect plastic.
Use the inverter at ambient temperatures of -10 to 40 (-10 to 50 for models designed for
18.5kW motors or larger).
Note) The inverter produces heat. When installing it in a cabinet, consider its ventilating
condition and internal space. When an inverter for 15kW motors or smaller is installed in a
cabinet, it is advisable to peel off the label on the top of the inverter. Models for 18.5kW motors
or larger can be used at ambient temperatures of up to 50 . (These models have no label on
their top.)
Do not install the inverter in any place subject to vibration.
Note) If you intend to install it in a place subject to
vibration, you should take measures to protect it
from vibration. In such a case, contact your
Toshiba dealer in advance.
