OK, just forgot you mean Bugle.
I can't find exact layout of wires' colors, but in reality, according to the datasheet:
- there should be 3 wires grouped together. The 2 with highest resistance are for primary for 230V
- 2 other groups (2 wires in each) should have near the same resistance (low). Find the wires by using the ohmmeter and then try to connect one of the wire from the first 15V group to on of the wire from the second 15V group. Connect the primary to an AC source and measure voltage across the free (not connected) leds. If the reading is around zero - then you connected the secondaries in wrong phase. Exchange the wires in one of the group and check again. There should be around 30V across the free leds.Then the primary should go to outer holes from the input side of the power supply (or connect them directly to IEC inlet), the secondaries should go in the order they connected during testing to the holes from the low-voltage side of the power supply PCB.
