Warning:
1. The main circuit adopts three-phase four-wire input without requirement for phase sequence.
2. SCR is a product with big current, please keep in mind that terminals (R.S.T) and (U.VW) shall not be locked tightly, or SCR will be burned by terminal heating.
3. There is a fast fuse is burned out, and do not use the one with higher fusing ampere.
4. For Y connection load, the center could not be connected with zero line, or SCR will lose control.
5. During the use of module, when the load power is big or the radiating consideration is bad, please consider wind cooling..
