WARNINGS!
The heatsink over temperature protection is designed to operate under normal
conditions and will operate in case abnormal conditions occur:
•
Incorrect starter selection
•
Too frequent starting at maximum conditions
•
Repeated starting under fault conditions
•
Extended low overload
•
Insufficient ventilation
•
Other abnormal conditions
Note
-
In case of frequent starting the internal thyristors may overheat before the
heatsink reaches its over-temperature protection of 85ºC, thus causing
component malfunction.
