Insert both sides of core wire of the power cable into
the connection sleeve.
•
Method 1: Push the core wire into the sleeve from
both sides.
•
Method 2: Twist the wire cores together and push
it into the sleeve.

Using a crimping tool, compress the two points and
flip it over and compress another two points in the
same location.
•
The compression dimension should be 8.0.
•
After compressing it, pull both sides of the wire to
make sure it is firmly pressed.
5
Wrap it with the insulation tape twice or more and
position your contraction tube in the middle of the
insulation tape.
Three or more layers of insulation are required.
6
Apply heat to the contraction tube to contract it.
7
After tube contraction work is completed, wrap it with
the insulation tape to finish.
CAUTION
•
Make sure that the connection parts are not exposed
to outside.
•
Be sure to use insulation tape and a contraction tube
made of approved reinforced insulating materials
that have the same level of withstand voltage with
the power cable. (Comply with the local regulations
on extensions.)
