Do not mount VFD in direct sunlight or near other heat sources.
The VFD should be mounted in a Pollution Degree 2 environment. If VFD is going to
be installed in an environment with a high probability of dust, metallic particles, mists,
corrosive gas or other contaminants, the VFD must be mounted inside the appropriate
electrical enclosure with proper NEMA, UL or IP rating and adequate cooling. If VFD
is mounted inside an enclosure, please consult factory for ambient temperature
considerations.
Mount VFD using proper screws or bolts.
When two or more VFDs are installed in a ventilated enclosure, the cooling system
should provide adequate airflow for all the VFDs. Do not install VFD above another
heat source (another VFD, inductive reactors, etc.) Refer to figure 4.1.2.
