Notes:
(1) Terminal tightening torque: 0.22 N m to 0.25
N m
(2) Carefully strip the cover so as not to damage
the core wires.
(3) Connect the core wires without twisting them.
(4) Connect the core wires without soldering them;
otherwise, they may break due to vibration.
(5) After connection, do not apply stress to the
cable.
(6) Because of the terminal structure, if the wire is
tightened by a counterclockwise rotation, the
connection will fail. In such cases, pull out the
wire, check the terminal hole, and then connect
it again.
