(1) Termination of the cables

Solid wire: After the sheath has been stripped, the cable can be used as it is.

Approx. 10mm
(0.39inch)

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.
