2 As shown in the figure, peel off the shields from the
rubber or wire of the power cable.
• Peel off 20 mm of cable shields from the
preinstalled tube.
CAUTION
• For information about the power cable
specifications for indoor and outdoor units, refer to
the installation manual.
• After peeling off cable wires from the preinstalled
tube, insert a contraction 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.)
