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.
0-40°C at nominal current. Over 40°C use the
derating curve.
-25°C a 70°C
Don't install at direct sun light, where there
are conductive dust, corrosive gas, vibration or
water and also in salty environmental.
Up to 1000 meter over sea level. For higher
altitude reduce the nominal current of 2% for
each 100m over 1000m
From 5 to 95% without condense and ice
Up to 2nd Level ref. IEC 60947-1 6.1.3.2
