Wiring - SMC Networks PFMC7501-L 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.
