4.1 Crimping 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
PVC insulation tape. This
document uses heat shrink
tubing as an example.
•
When using a heat gun,
protect devices from being
scorched.
