Clearances
The SD300 VFD must be installed in vertical position, and firmly fastened
through the dedicated anchorages placed in the rear part of the drive that
avoid any movement.
If the equipment is installed inside a cabinet, ensure that the hot air expelled
from the VFD flows outside. This hot air can recirculate, and cause the drive
to suffer from overheating. To guarantee a suitable ambient temperature,
avoid the recirculation of air and follow the minimum clearance distances, as
indicated below.
