Installation of the inverter and enclosure design
Vibration, impact
The vibration resistance of the inverter is up to 2.9 m/s
Y, Z axes. Subjecting the product to vibration and impacts over a long period of time may loosen the structures and cause
poor contacts of connectors, even if those vibration and impacts are within the specified values.
Especially when impacts are applied repeatedly, caution must be taken because such impacts may break the installation feet.
Countermeasure
• Provide the enclosure with rubber vibration isolators.
• Strengthen the structure to prevent the enclosure from resonance.
• Install the enclosure away from the sources of the vibration.

Amount of heat generated by the inverter
Installing the heat sink inside the enclosure
The following tables shows the amount of heat generated from the converter unit or the inverter of which the heat sink is
installed inside the enclosure.

• The figures indicate the amount of heat generated when the output current is the rated current.
Protruding the heat sink through a panel
When the heat sink is protruded through a panel, the amount of heat generated by the inverter and converter unit is shown in
the following tables. (For the details on protruding the heat sink through a panel, refer to
