• The connection of the input signal is only an example.
• Keep the CN1 and CN2 wires as short as possible.
• Do not run transmission wiring along 230 V / 400 V CA power supply cables. Leave a distance of more than 30 cm between them.
(Intersection are occasionally allowed).
• If you install the wires along a power supply wire, insert the wires in a metal conduit tube and ground one end of the tube.
• The maximum wiring length is 70 m. If you use this function, it is recommended that you use safety devices such as an electrical
leakage breaker or a smoke detector.
