2. INSTALLATION AND WIRING
2.3 Installation of the inverter and enclosure design
This system is low in cost and generally used, but the
enclosure size increases as the inverter capacity
increases. This system is for relatively small capacities.
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 inverter capacity.
This system has restrictions on the heat sink mounting
position and area. This system is for relatively small
This system is for general indoor installation. This is
appropriate for enclosure downsizing and cost
reduction, and often used.
This system is a totally enclosed type, and is
appropriate for enclosure downsizing.
