Install the AC motor drive in a metal cabinet. When installing one drive below another one,

use a metal separation between the AC motor drives to prevent mutual heating and to
prevent the risk of fire accident.
Install the AC motor drive in Pollution Degree 2 environments only:

Normally only nonconductive pollution occurs and temporary conductivity caused by
condensation is expected.

When installing one AC motor drive below another one (top-bottom installation), use a metal separation
between the drives to prevent mutual heating. The temperature measured at the fan's inflow side must
be lower than the temperature measured at the operation side. If the fan's inflow temperature is higher,
use a thicker or larger size of metal seperation. Operation temperature is the temperature measured at
50mm away from the fan's inflow side. (As shown in the figure below)
