1) The main circuit uses three-phase four-wire input, no phase sequence requirements.
2) This product is a high current product, please be sure to lock the terminals(A1,B1,C1)and(A2,B2,C2), otherwise it will cause the terminal heat and product burnt.
3) This product must be equipped with a suitable heat sink, and between the radiator and the module coated with thermal grease. If power is big,or cooling conditions are not good, please consider the use of air-cooled or water-cooled.
4) It is forbidden to output a large current at a small conduction angle(Module at high input, low output voltage), which can cause the module to heat up and damage.
5) Module protection: short circuit protection using semiconductor dedicated fast fuse. For overvoltage protection, recommended simultaneously use of resistance absorption and varistor. Its selection principle is the same with the SCR module.
6) Selected module current should be more than 2 times the load current for resistive load; For inductive load,module current should be more than 3 times the load current.
