18 VLT ® Soft Starter Pocket Guide
Extreme Conditions: How can soft starters be selected
for extreme conditions?
Soft starter ratings are based on specifi c operating conditions. These
generally specify start time, start current, starts per hour, duty cycle
and environmental factors such as ambient temperature and altitude.
If the soft starter will be used outside these conditions, the rating must
be revised according to the manufacturer’s instructions.
Ratings for Danfoss soft starters are published in the soft
starter’s Design Guide. Alternatively, WinStart can be used
to model requirements outside the published ratings.
