1. Mount the AC motor drive vertically on a flat vertical surface with screws. Other mounting directions are not
allowed.
2. The AC motor drive generates heat during operation. Allow sufficient space around the unit for heat
dissipation. When you install the AC motor drive in a confined space (for example a cabinet), the surrounding
temperature must be meet specifications of operation (as shown in chapter 1.2.1) with good ventilation. DO
NOT install the AC motor drive in a space with poor ventilation.
3. The heat sink temperature may rise to 90°C when running. The metallic material on which the AC motor
drive is mounted must be noncombustible, be excellent at thermal dissipation and be able to withstand this
high temperature.
4. When installing multiple AC motor drives in the same cabinet, mount them in a row with enough space
between for ventilation. When installing one AC motor drive below another one, use a metal separator
between the AC motor drives to prevent mutual heating.
