1.23 Low-voltage Power Supply PCB and Power Inlet (1) Remove two screws "g" and take off the rear underbar. (2) Remove screw "h." (3) Slightly lift up the low-voltage power supply PCB and disconnect the heater harness and mainLV-engine harness. The low-voltage power supply PCB is connected to the power inlet with soldered lead wires. (4) Remove screw "i." (5) While holding up the low-voltage power supply PCB, take out the power inlet from the main chassis to the inside in the direction of the arrow shown below. (6) To separate the power inlet from the low-voltage power supply PCB, unsolder the two lead wires from the PCB. g Low-voltage power supply PCB "h" "g" Rear underbar „.7 (Front underbar) O Power inlet Main chassis placed upside down Main-LV-engine harness Cutout "X" provided in the support film Heater harness (Rear) Power inlet Grounding wire "g" and "i": Taptite, cup S M3x6 "h": Taptite, cup S M3x6 0 (Tightening torque: 0.5 N•m) Cutout "Y" provided in the support film Routing the grounding wire IV - 61
