Installation of the converter unit
Installation of the converter unit
• Install the converter unit on a strong surface securely with screws.
• Leave enough clearances and take cooling measures.
• Avoid places where the converter unit is subjected to direct sunlight, high temperature and high humidity.

Comment
Natural
Natural ventilation (enclosed
type / open type)
This system is low in cost and generally used, but the
enclosure size increases as the converter unit capacity
increases. This system is for relatively small capacities.
Natural ventilation (totally
enclosed type)
Being a totally enclosed type, this system is the most
appropriate for hostile environment having dust, dirt, oil
mist, etc. The enclosure size increases depending on
the converter unit capacity.
Forced air
Heat sink cooling
This system has restrictions on the heat sink mounting
position and area. This system is for relatively small
capacities.
Forced ventilation
This system is for general indoor installation. This is
appropriate for enclosure downsizing and cost
reduction, and often used.
Heat pipe
This system is a totally enclosed type, and is
appropriate for enclosure downsizing.
