■ Wiring
○ Connection
•
Connections should only be made with the power supply turned off.
•
Use separate routes for the Pressure switch 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.
