• The connection of the input signal is only an example.
• Keep the CN1 and CN2 wires as short as possible.
• Do not run the wires along 230 V/400 V CA power cables separately install them at a distance of more than
30cm. (The cables may intersect.)
• 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.
