Multiple drives, side-by-side vertical installation
When installing one AC motor drive below another one (top-bottom installation), use a metal separator
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 separator. See diagram below. Operation temperature is the
temperature measured at 50 mm away from the fan’s inflow side.
