3. Insert both sides of core wire of the power cable into the connection
sleeve.
f

Method 2
Twist the wire cores together and push it into the sleeve.

t
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.
CAUTION
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.
