1. Strip the sheath off the cable to leave the 
conductor with an L1 length exposed. Ensure 
that the value of L1 is equal to the tail length of 
the OT terminal.

2. Lead the cable through the heat shrink 
tubing and place the OT terminal on the 
exposed conductor.

3. Use the crimping tool to crimp the joint parts 
of the bare crimping terminal and the 
conductor.

4. Install the heat shrink tubing.

Crimping tool

NOTICE

Heat the heat shrink tubing until it tightly clings to the 
connector. Do not overheat the heat shrink tubing, 
preventing the insulation layer being burnt.

The heat shrink tubing must be fixed to cover the 
cable conductor.

NOTICE

Ensure that the metal conductor of the cable is not 
damaged when stripping the sheath off the cable.

NOTICE

The contact terminal should contact the insulation sheath 
of the cable.
After the conductor is fed into the OT terminal, the 
protruding part of the conductor, L2 must not be longer 
than 2 mm.
