AC-DC switching power supply, how to connect, input AC, AC, FG three ends
but generally follow the principle is: FireWire to pass through the circuit breaker as a protection, zero line generally connected to the zero line card. FG ground wire.
If not marked L fire line, N zero line; AC AC can be connected to the fire line and the zero line;
Input AC, AC, respectively, then the power line FireWire, zero line, pay attention to view the two input terminals, preferably the power of the internal fuse connected to the other end of the line connected to the other end of the line, the fire line can also be connected to the normal line. FG ground wire.
