3. Not subjected to production testing

4. To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals must be used

together with a proper hardware/software strategy. If the devices operates under abnormal conditions this hardware/software solutions

must limit the duration and number of activation cycles.
