Method 2
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.
