Multiple drives side-by-side vertical installation (Frame D0–H )
Ta: Frame D0–G
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)

NOTE
The stated A to D in the table above are minimum mounting clearances. A drive fails to follow the minimum mounting
clearances may cause the fan to malfunction and heat dissipation problem.
