Questions and answers
can these drives be installed in an outdoor environment without being in a panel, for example on the outside wall of an outdoor HVAC unit
No, Danfoss CDS 302 drives should not be installed outdoors on the exterior wall of an HVAC unit without a panel. They require protection from environmental conditions such as moisture, corrosion, harmful airborne contaminants, and must be mounted on a flat solid surface with proper airflow clearance.
