Installation
Caution:
Don't install near the hot elements or near the units that could give
electromagnetic interferences.
The CD3000E Thyristor unit must be always mounted in vertical position to improve air cooling on heat-
sink. Maintain the minimum distances in vertical and in horizontal as represented.
When more unit has mounted inside the cabinet maintain the air circulation like represented in figure.
Sometimes is necessary installing a fan to have better air circulation.
