Note : 1. T1 describes rising time of 0V to 24V and is not applied at restarting time.
2. When the Inverter is shut-down by ARC protection, T3 need 3.3sec
3. When VBL (24V) is supplied always, there is no reliability problem.
4. T4(max) is less than T2.
5. In T7 section, ExtVbr-B should be duty 100% and Vbr-A is recommended 3.3V.
