The signal line should be pulled up to the positive side of a 5 supply with an approximate 10kΩ resistor. 4: The wiring between the power D-link capacitor and the /N1 terminals should be as short as possible to protect against catastrophic high surge voltage. r extra precaution, a small film type snubber capacitor (0.1~0.22µF, high voltage type) is recommended to mount closely to the and N1 terminals. 5: output pulse width (tfo) should be determined by connecting external capacitor between FO and N terminals. (Example : tfo=2.4ms(typ.) at FO=22nF) 6: High voltage (1200 or more) and fast recovery type (less than 100ns) diodes should be used for the bootstrap circuit. 7: It is recommended to insert a Zener diode (24/1) between each pair of control supply terminals to prevent surge destruction. 8: To prevent LI from surge destruction, it is recommended to mount a fast recovery type diode between N and, N, terminals.

Since the S fault may be repetitive, it is recommended to stop the system and check the fault, when the signal is received.
