2. As shown in the figure, peel off the shields from the
rubber and wire of the power cable.
• Peel off 20 mm of cable shields from the pre-
installed tube.

3. 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.
4. 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.)
