Wiring - SMC Networks PF2A7 Series Operation Manual

■Wiring

Connections should only be made with the power supply turned off.
Use separate routes 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 the wiring
Align the lead wire connector with the connector key groove, and insert vertically.
Connection is complete when the knurled part is fully tightened. Check that the connection is not loose.
●Connector Pin numbers
When the lead wire with connector designated for the PF2A7 is used, the wire colours will apply as shown in
the diagram.
