8. Not subjected to production testing
9. 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.
