5) mulTiple drives side-by-side and over/under (frames a–g)
•
When installing one AC motor drive below another one (over/under 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 larger metal separator�
•
T
a
= ambient air temperature measured at 50mm away from the fan’s inflow side�

drives frames A to G. Failure to follow the minimum mounting clearances
may cause the fan to malfunction and cause a heat dissipation problem.
