Incorrect wiring can break the Pressure switch.
•Do not perform wiring while the power is on.
Otherwise damage to the internal parts can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the product can malfunction due to interference of noise and surge voltage from power and high voltage
cables to the signal line. Route the wires (piping) of the product separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
•Design the system to prevent reverse current when the product is forced to operate for operational
check.
Depending on the circuit used, insulation may not be maintained when operation is forced, allowing reverse current
to flow, which can cause malfunction and damage the product.
•Keep wiring as short as possible to prevent interference from electromagnetic noise and surge voltage.
Do not use a cable longer than 10 m.
Wire the DC(-) line(blue) as close as possible to the power supply.
•When analog output is used, install a noise filter (line noise filter, ferrite element, etc.) between the
switch-mode power supply and this product.
*Environment

2. Hold the tube and insert it into the One-touch fitting slowly until it will bottom out.
Warning
■Do not use the Pressure switch in a place where electrical static charge will be problem.
It can cause the error and breakage of the system.
•Keep a margin for tube length to prevent twist, tensile and moment load from applying to the fitting and
tube.
•When using a tube manufactured by another company, check its outside diameter accuracy satisfies the
following value.
1) Nylon tube: ±0.1 mm at maximum
2) Soft nylon tube: ±0.1 mm at maximum
3) Polyurethane tube: +0.15 mm/-2 mm at maximum

■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.
○Connector
Connecting/Disconnecting
•When mounting the connector, insert it straight into pins with holding the lever and connector body by
fingers and press fit the nook of the lever to the concave of the housing to lock.
•When removing the connector, press down the lever by thumb to let its nook come off from the concave
and pull out the connector straight.
