Wiring - SMC Networks PF2MC7 Series Operation Manual

■Wiring

Connection
•Connections should only be made with the power supply turned off.
•Use a separate route for the product wiring and any power or high voltage wiring. Otherwise, malfunction
may result due to noise.
•Ensure that the FG terminal is connected to ground when using a commercially available switch-mode
power supply. When a switch-mode power supply is connected to the product, switching noise will be
superimposed and the product specification can no longer be met. This can be prevented by inserting a
noise filter, such as a line noise filter and ferrite core, between the switch-mode power supply and the
product or by using a series power supply instead of a switch-mode power supply.
Connecting/Disconnecting
•Align the lead wire connector with the connector key groove, and insert it straight in. When the knurled part
is fully tightened. Check that the connection is not loose.
•When removing the connector, unlock the knurled part and pull out the connector straight.
