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 8.0.
• After compressing it, pull both sides of the wire to
make sure it is firmly pressed.
Method 1
Compress it 4 times.
