※
The specified distances are only applicable in open spaces. As shown
in the diagram on the left, if the units are being installed in an enclosed
space, such as distribution channel or chassis, install ventilation or air
conditioning systems to keep the ambient temperature under the
operating temperature.
※
The table shows the required airflow rate for each model when
installing single units in an enclosed space. For multiple units, multiply
the required airflow rate by the number of units installed.
※
Refer to the “Airflow Rate for Cooling” table below when selecting and
designing ventilation systems.
※
Refer to the “Power Dissipation of REG” table below for the design of
air conditioning systems.

The table shows the required airflow rate for each model when installing single units in an enclosed
space.
※
For multiple units, multiply the required airflow rate for single-unit installation by the number of units
installed.
