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.

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.
