2. Installation and
Connection
2-1 Operating Environment
Install the inverter in an environment described
in Table 2-1-1.
Table 2-1-1 Operating environment
2-2 Installation Method
(1) Securely mount the inverter in the upright
position on a rigid structure so that the
"VXSM" characters face front. Avoid
mounting the inverter upside down or avoid
mounting horizontally.
(2) Allow clearances for cooling air shown in
Fig. 2-2-1 to cool down the inverter which
generates heat during operation. The
generated heat is radiated upward. Do not
install the inverter below a heat sensitive
device.
WARNING
Install the inverter on a nonflammable
material such as metal.
Otherwise fire could occur.
CAUTION
Do not allow lint, paper, wood chips,
dust, metallic chips or other foreign
matter in the inverter or do not allow them
attached to the heat sink.
Otherwise fire or an accident could occur.
(3) The temperature of the heat sink rises to
about 90 degrees C during operation of the
inverter. Mount the inverter on a base made
of a material withstanding the temperature
rise.

(4) When installing the inverter inside a control
panel or the like, take full consideration for
ventilation so that the ambient temperature
of the inverter does not exceed the
specification requirements. Do not install
the inverter in a poorly ventilated small
enclosure.
(5) When storing multiple inverters inside a
single unit or inside a control panel,
horizontal installation is recommended to
reduce mutual temperature effects. When
an vertical layout is adopted for an
unavoidable reason, install a partition plate
or the like between inverters to isolate the
heat of the lower inverter.
