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.
Method 1
Connection sleeve
CAUTION
• If cable wires are connected without using connecting
sleeves, their contact area becomes reduced, or corrosion
develops on the outer surfaces of the wires (copper wires)
over a long time. This may cause an increase of resistance
(reduction of passing current) and consequently may result in
a fire.
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 0.31 inch (8.0 mm).
• After compressing it, pull both sides of the wire to make sure
it is firmly pressed.
Method 1
Compress it 4 times
0.20 inch (5 mm)
5 Apply heat to the contraction tube to contract it.
