Make sure to use the jumper for the following models in case of AC85-132V input. | P50E,P100E,P150E, PMC50E-PMC100E, P1500E, AD240,AD480 |

| AC voltage is not applied to power supply correctly. - 2 Is external fuse blown? |
1)If the built-in fuse is blown, return the power supply to us for repair. 2)If the built-in fuse has no problem, change the external fuse to one that can withstand the inrush current of the power supply and has the same voltage/current rating as the built-in fuse. |
