2. Reassembly of the power supply unit
(1) Mounting the rotor ass'y
Before inserting the Rotor [102]{99} into the Housing [52]{49}, mount the Rotor [102]{99} on the Gear
Cover [99]{96}.
NOTE: Without the gear cover, the Rotor [102]{99} will be strongly attracted and fixed to the
Stator Sensor PCB Set [45]{42} by its own magnetic force. Be careful not to get your
hand caught between the Rotor [102]{99} and the Stator Sensor PCB Set [45]{42}.
(2) Wiring of the controller set (See the figure on the next page.)
• Connect the terminals of the three internal wires (red, white, and black) coming from the Stator
Sensor PCB Set [45]{42} to the Controller [53]{50} terminals of the same colors. Insert each terminal
into the mating terminal securely until it contacts the innermost end.
• Connect the 5-wire connector of the Stator Sensor PCB Set [45]{42} to the Controller [53]{50}
connector. Do not reverse the connector orientation.
• Connect the 8-wire connector of the Panel [98]{95} to the Controller [53]{50} connector. Do not
reverse the connector orientation.
(3) Wiring of the filter PCB set (See the figure on the next page.)
• Connect the two terminal-equipped internal wires of the Controller [53]{50} to those of the Filter PCB
Set [62]{59}. The internal wires are connectable with either terminal. Insert each terminal into the
mating terminal securely until it contacts the innermost end.
• Connect the two core-exposed internal wires of the Filter PCB Set [62]{59} to Piller Terminal (A)
[71]{68}.
(4) Wiring of the switch (See the figure on the next page.)
• Connect the two core-exposed internal wires of the Controller [53]{50} to the terminals No. 2 and No.
3 of the Switch [69]{66}. The internal wires are connectable with either terminal.
(5) Wiring of the cord (See the figure on the next page.)
• Connect the core-exposed internal wires of the Cord [75]{72} to Piller Terminal (A) [71]{68}. The
internal wires are connectable with either terminal.
