Installation
Before to install, make sure that the Thyristor
unit have not damages.
If the product has a fault, please contact the
dealer from which you purchased the product.
Verify that the product is the same thing as
ordered.
The 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.
