Equipment Peripheral Dimension Conditions
Please note the installation method, the direction of installation!
• If the inverter is not installed vertically, its cooling performance may be degraded and tripping or
inverter damage may result.
• Install the inverter vertically and securely with screws or bolts on a surface that can bear the inverter
weight and is free from vibrations.
Surface on which to install the inverter
• The inverter will reach a high temperature (up to about 150°C) during operation. Install the inverter on
a vertical wall surface made of nonflammable material (e.g., metal) to avoid the risk of fire. In addition
be sure to confirm the structure to bear the Inverter weight.
• Keep sufficient distance between the inverter and other heat sources (e.g., braking resistors and
reactors) so that the heat discharged from the heat sources does not affect the inverter.
