• 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.
