2. After installing the crimp terminal to the stripped end of the signal wires,
apply vinyl tape or heat-shrinking tube.
Note Always use the specified crimping tool to install crimp terminals. When a
crimping tool is not used, the terminal cannot be correctly crimped and may
cause the cables to be disconnected.
3. Check the direction of the connector and insert each of the signal wires securely
into the back of the connector holes.

Note Before inserting the signal wires, check that the connector’s lock screws are
sufficiently loose. If the screws are not loose when the signal wires are
inserted, the signal wires will enter the gap at the back of the connector rather
than the side to be tightened and may not be secured.
4. Tighten the signal wires securely using the connector’s signal wire lock
screws. A standard screwdriver that is only slim at the end cannot be inserted
into the back of the screw hole, so use a small flat-blade screwdriver
that is of uniform thickness. The tightening torque is 0.22 to 0.25 N⋅m.
