Precautions

1. Main circuit uses 3-phase 3-wire input, no phase sequence is required.
2. SCR is high current product, please be sure to lock the (R.S.T) and (U.V.W) terminals, otherwise the terminals will heat up and the SCR will burn out.
3. SCR has a built-in fast fuse for over current and short circuit protection. If the fuse is blown due to overcurrent, first check the load for faults such as short circuit and partial discharge. After troubleshooting, open the panel and replace it. Be sure to replace it with fuse of the same specification. Be careful not to increase amperage of the fuse at will.
4. When using the load Y type wiring method, center point cannot be connected to zero line, otherwise the SCR will lose control. If 3-phase load is unbalanced, center point must be connected to zero line.
