Wiring Method - SMC Networks D-MH1AD Series Operation Manual

■Wiring method

○Wiring connections
●Perform wiring connection work after turning off the power supply.
●Use a separate route for the product wiring. If wires and cables are routed together with power or high
voltage cables, malfunction may result due to noise.
●If using a commercially available switching power supply, be sure to ground the frame ground (FG)
terminal. If a commercially available switch-mode power supply is connected for use, switching noise will
be superimposed and the product specifications will not be met. In that case, insert a noise filter such as
a line noise filter/ferrite between the switching power supplies or change the switching power supply to a
series power supply.
