5. The heat sink temperature may rise to 90°C when running. The material on which the AC motor
drive is mounted must be noncombustible and be able to withstand this high temperature.
6. When AC motor drive is installed in a confined space (e.g. cabinet), the surrounding
temperature must be within 10 ~ 40°C with good ventilation. DO NOT install the AC motor drive
in a space with bad ventilation.
7. Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the
heatsink.
8. When installing multiple AC more drives in the same cabinet, they should be adjacent in a row
with enough space in-between. When installing one AC motor drive below another one, use a
metal separation between the AC motor drives to prevent mutual heating.
