2. INSTALLATION AND WIRING
2.3 Installation of the converter unit and enclosure design
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.
2.3.2
Amount of heat generated by the converter unit
The amount of heat generated by the inverter unit and converter unit is shown in the following tables.
NOTE
• The amount of heat generated shown assumes that the output current is the inverter rated current, and the carrier frequency
is 1 kHz.
2.3.3
Cooling system types for converter unit enclosure
From the enclosure that contains the converter unit, the heat of the converter unit and other equipment (transformers, lamps,
resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower
than the permissible temperatures of the in-enclosure equipment including the converter unit.
The cooling systems are classified as follows in terms of the cooling calculation method.
• Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)
• Cooling by heat sink (aluminum fin, etc.)
• Cooling by ventilation (forced ventilation type, pipe ventilation type)
