NOTE
When encasing multiple brake units, install them in parallel as a
cooling measure.
Install the inverter vertically.
(2) Clearances around inverter
To ensure ease of heat dissipation and maintenance, leave at least the shown clearances around the inverter. At least the
following clearances are required under the inverter as a wiring space, and above the inverter as a heat dissipation space.

* When using the inverters at the ambient
temperature of 40 C (104 F) or less, the inverters
can be installed without any clearance between
them (0cm (0inch) clearance).
When ambient temperature exceeds 40 C (104 F),
clearances between the inverters should be 1cm
(0.39inches) or more (5cm (1.97inches) or more
for the FR-E720-240 and FR-E740-120, or more).
