Procedure
Step 1 Crimp an OT terminal.

Avoid scratching the core wire when stripping a cable.

The cavity formed after the conductor crimp strip of the OT terminal is crimped must wrap
the core wires completely. The core wires must contact the OT terminal closely.

Wrap the wire crimping area with heat shrink tubing or insulation tape. The heat shrink
tubing is used as an example.

When using a heat gun, protect the equipment from being scorched.
