Installation
Heat dissipation requirements
In order to have adequate air flow for ventilation, follow the suggested clearances when
installing one or more servo drives. The servo drive generates heat, therefore be aware of the
2
minimum distance (d) and the ambient temperature factor when installing multiple servo drives
(refer to the following diagrams). Avoid mounting one servo drive above one another. Keep the
bottom of the servo drive clear because the generated heat rises and causes higher
temperature for the drives mounted above.
Note: the following diagrams are not accurately scaled. Refer to the annotations on the diagrams.
