Sheath
Core
Twisted wire: Use the cable after stripping the sheath and twisting the core. At this time, take care to avoid
a short caused by the loose wires of the core and the adjacent pole. Do not solder the core as
it may cause a contact fault. Alternatively, a bar terminal may be used to put the wires
together.
