The LVPS has two fuses on the PCA.
The LVPS 24 V output is interrupted to the fuser and the high-voltage power supply if the cartridge-door interlock switch (SW501) is in the off position (cover open). WARNING! The product power switch only interrupts DC voltage from the LVPS. The AC voltage is present in the product when the power cable is plugged into a power receptacle and the power switch is in the off position. You must disconnect the product power cable before servicing the product. ENWW Engine control system 5
