1.4.2.6 Control Output and Transmission Output Wiring
▶ Before starting control output and transmission output wiring, be sure to turn off
the system, or else you will get an electrical shock.
▶ When connecting, do not mix up the input polarity, Connecting with the wrong polarity
can cause serious accidents.
▶ For input wiring, use a shielded cable. Ground the shield at one point.
