Revision July 2009, SW V1.1
1.
Mount the AC motor drive vertically on a flat vertical surface by using bolts or screws. Other
directions are not allowed.
2.
The AC motor drive will generate heat during operation. Allow sufficient space around the unit
for heat dissipation.
3.
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.
4.
When the 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.
5.
When installing multiple AC motor drives in the same cabinet, they should be adjacent in a row
with enough space. When installing one AC motor drive below another one, use a metal
separation barrier between the AC motor drives to prevent mutual heating. Refer to figure below
for details.
6.
Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the
heatsink.
