Note 1 : Input drive is High-Active type. There is a 3.3kΩ(min.) pull-down resistor integrated in the IC input circuit. To prevent malfunction, the

2 : Thanks to HVIC inside the module, direct coupling to MCU without any opto-coupler or transformer isolation is possible.
3 : F
4 : To prevent erroneous protection, the wiring of A, B, C should be as short as possible.
5 : The time constant R1C4 of the protection circuit should be selected in the range of 1.5-2µs. SC interrupting time might vary with the
6 : All capacitors should be mounted as close to the terminals of the DIP-IPM as possible. (C1: good temperature, frequency character-
7 : To prevent surge destruction, the wiring between the smoothing capacitor and the P, N1 terminals should be as short as possible.
8 : Two V
9 : It is recommended to insert a Zener diode (24V/1W) between each pair of control supply terminals to prevent surge destruction.
10 : If control GND is connected to power GND by broad pattern, it may cause malfunction by power GND fluctuation. It is recommended
wiring of each input should be as short as possible. When using RC coupling circuit, make sure the input signal level meet the turn-on
