A. For solid core wiring
(1) To connect the electrical terminal, follow the below diagram and connect after looping
it around the end of the cable.
(2) Use the specified cables, connect them securely, and fasten them so that there is no
stress placed on the terminals.
(3) Use an appropriate screwdriver to tighten the terminal screws. Do not use a screw-
driver that is too small, otherwise, the screw heads may be damaged and prevent the
screws from being properly tightened.
(4) Do not tighten the terminal screws too much, otherwise, the screws may break.
(5) See the table for the terminal screw tightening torques.
(6) Please do not fix 2 power supply cables with 1 screw.

WARNING
When using solid core cables, do not use the ring terminal. If you use the solid core
cables with the ring terminal, the ring terminal’s pressure bonding may malfunction and
cause the cables to abnormally heat up.
B. For strand wiring
(1) Use ring terminals with insulating sleeves as shown in the figure below to connect to
the terminal block.
(2) Securely clamp the ring terminals to the cables using an appropriate tool so that the
cables do not come loose.
(3) Use the specified cables, connect them securely, and fasten them so that there is no
stress placed on the terminals.
(4) Use an appropriate screwdriver to tighten the terminal screws. Do not use a screw-
driver that is too small, otherwise, the screw heads may be damaged and prevent the
screws from being properly tightened.
(5) Do not tighten the terminal screws too much, otherwise, the screws may break.
(6) See the table for the terminal screw tightening torques.
(7) Please do not fix 2 power supply cables with 1 screw.

WARNING
Use ring terminals and tighten the terminal screws to the specified torques, otherwise,
abnormal overheating may be produced and possibly cause heavy damage inside the
unit.

CAUTION
To peel the film from the lead cable, use a dedicated tool that will not damage the
conductor cable.
When installing a screw on the terminal block, do not cut the cable by overtightening the
screw. On the other hand, an under tightened screw can cause faulty contact, which will
lead to a communication failure.
6.4. Connection of wiring
(1) Remove the electric compo-
nent box.

RFM
CAUTION
Do not remove the RFM fixing screws. If the stays are removed, the electric component
box will fall.
If you use as “Floor console”, you must remove screws and RFMs (2 position).
When removing the electric
component box, remove the
clamp from the cables.
After completing the work,
fasten the cables as they
were originally by installing
the clamp.
