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.
