Chapter 2 InstallationCT2000 Series
Multiple drives, side-by-side installation (Frame D) Install metal separation between the drives.
Multiple drives side-by-side installation and in rows (Frame B,C )
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 seperature. Operation temperature is the temperature measured at 50mm
away from the fan's inflow side. (As shown in the figure below)
