2. INSTALLATION AND WIRING
2.3 Installation of the converter unit and enclosure design
• When encasing multiple inverters and converter units in an enclosure, install them in parallel as a cooling measure.
• For heat dissipation and maintenance, keep clearance between the converter unit and the other devices or enclosure
surface. The clearance below the converter unit is required as a wiring space, and the clearance above the converter unit
is required as a heat dissipation space. (Air flow must not be interrupted in the heat dissipation space.)
• When designing or building an enclosure for the converter unit, carefully consider influencing factors such as heat
generation of the contained devices and the operating environment.
*1
Side-by-side installation (0 cm clearance) is available. Note that clearance to pass cables is required. (Refer to
*2
A 10 cm or more clearance is required below the bottom of the enclosure (regardless of the installation feet).
*3
There needs to be a space of at least 60 cm in front of the converter unit to replace the cooling fan. Refer to
for fan replacement.
Installation orientation of the converter unit
Install the converter unit on a wall as specified. Do not mount it horizontally or in any other way.
Above the converter unit
Heat is blown up from inside the converter unit by the small fan built in the unit. Any equipment placed above the converter unit
should be heat resistant.
Encasing multiple inverters and converter units
When multiple inverters and converter units are placed in the same enclosure, arrange them horizontally as shown in the figure
below. Do not place multiple converter units or the converter unit and the inverter vertically. The exhaust air temperature of the
converter unit may be increased.
When mounting multiple inverters and converter units, fully take caution not to make the surrounding air temperature of the
inverter and the converter unit higher than the permissible value by providing ventilation and increasing the enclosure size.
