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 wiring of each in-
put should be as short as possible. When using RC coupling circuit, make sure the input signal level meet the turn-on and turn-off threshold voltage.

: Thanks to HVIC inside the module, direct coupling to MCU without any opto-coupler or transformer isolation is possible.
: FO output is open drain type. It should be pulled up to the positive side of a 5V power supply by a resistor of about 10kΩ.
: To prevent erroneous protection, the wiring of A, B, C should be as short as possible.
: 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
wiring pattern. Tight tolerance, temp-compensated type is recommended for R1, C4.

: All capacitors should be mounted as close to the terminals of the DIP-IPM as possible. (C1: good temperature, frequency character-
istic electrolytic type, and C2, C3: good temperature, frequency and DC bias characteristic ceramic type are recommended.)
: To prevent surge destruction, the wiring between the smoothing capacitor and the P, N1 terminals should be as short as possible.
Generally a 0.1-0.22µF snubber between the P-N1 terminals is recommended.
: Two VNC terminals (9 & 16 pin) are connected inside DIP-IPM, please connect either one to the 15V power supply GND outside and
leave another one open.
: 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
to connect control GND and power GND at only a point.
11 : The reference voltage Vref of comparator should be set up the same rating of short circuit trip level (Vsc(ref): min.0.43V to max.0.53V).
12 : OR logic output high level should exceed the maximum short circuit trip level (Vsc(ref): max.0.53V).
