3. Routing the Charging Wire
You can route the charging wire (not the grid
wire) of all charging assemblies in the same way;
the following uses the primary charging wire:
1) Remove the shielding plate (right, left) of the
charging assembly. To prevent deformation
(slack) of the primary charging assembly,
remove the left and the right shielding plates
independently.
(Do not loosen the screws q on the left and
the right shielding plates at the same time.)
2) Remove the wire cleaner.
Caution:
Remove the lids (2 pcs.) for other charging
assemblies.
3) Free a length of about 5 cm charging wire from
the reel, and form a loop with a diameter of
about 2 mm.
Reference:
To form a loop, wind the charging wire once
around a hex key; then, turn the hex key
three to four times, and twist the charging
wire.
4) Cut the excess end of the twisted charging
wire by a nipper.
5) Hook the loop on the stud.
