*1
Side-by-side installation (0 cm clearance) is possible. Note that clearance for the cables is required. (Refer to
*2
A clearance of 10 cm or more is required below the bottom of the enclosure (regardless of whether the inverter is mounted on legs).
*3
There needs to be a space of at least 60 cm in front of the inverter to replace the cooling fan. Refer to
NOTE
• Refer to the Option Installation Manual for the installation method using the FR-A8SR (optional slide rail) or a lifter.
Installation orientation of the inverter
Install the inverter on a wall as specified. Do not mount it horizontally or in any other way.
Above the inverter
Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter 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.
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.

Arrangement of multiple inverters and converter units
Arrangement of the ventilation fan and inverter
Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a
ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow. (Air passes
through areas of low resistance. Make an airway and airflow plates to expose the inverter to cool air.)
