6. 4. Transmission line
CAUTION
• Caution when wiring cable
When stripping off the coating of lead wire, always use the exclusive tool such
as a wire stripper. If there is no exclusive tool available necessarily, carefully
strip the coating by a cutter etc. so that the conductive wire is not damaged.
If it is damaged, it may lead to an open circuit and a communication error.
• Pay attention to the following points while attaching wires on the terminal board.
Do not attach 2 wires on one side.
Do not twist wires.
Do not cross the wires.
Do not shorted at edge at root.
