• Do not pull the lead wire with force or lift the main unit by holdingthe lead wire. (Pulling strength less than 35N)

• Do not insert wire or other articles into the pressure port.• Connect wires and cables correctly.• Do not perform wiring while power is on.• Do not wire with power cable or high-voltage cable in the same wireroute.

• Connect Terminal FG to ground when using a switching regulatorobtained on the commercial market.

For one-touch fitting type:• Do not apply unnecessary forces such as twisting, pulling, momentloads, etc. on fitting or tubing.

• When using a brand of tubing other than SMC, be careful of thetolerance of the tube’s O.D.1) Nylon tube ±0.1mm2) Soft nylon tube ±0.1m3) Polyurethane tube +0.15mm, -0.2mm

Safety Instructions

Safety Instructions (continue)

• Insert a noise filter (line noise filter, ferrite element or other element)between the switching regulator and pressure switch when analogoutput is used.

• Do not use with a corrosive or inflammable gas or liquid.• Do not press the setting buttons with a sharp pointed object.• Turn power on for 20 to 30 minutes before detecting fine pressure.Initial drift of about ±1% occurs immediately after turning the power on.

• The direct-current power supply to combine should be a ULauthorization class 2 power supply based on UL1310, or a powersupply using a transformer which is class 2 based on UL1585.

• Only a pressure switch with UL mark on the body is UL approved.• This pressure sensor is for use with air only. Please contact SMC ifthe switch is to be used with other fluids.

Connection• Make connection after turning the power off.• Install the lead wire separately from the route for power cable orhigh-voltage cable. Otherwise, malfunction may potentially resultdue to noise.

• Be sure to ground Terminal FG when using a switching regulatorobtained on the commercial market. If the analog output isconnected to a switching regulator obtained on the market, switchingnoise will be superimposed and product specification can no longerbe met. This can be prevented by inserting a noise filter, such as aline noise filter and a ferrite element, between the switching regulatorand the pressure switch, or by using a seriespower supply instead ofa switching regulator.

Pipe Connection (One-touch Fitting Type)1.Cut the tube perpendicularly.2.Hold the tube, slowly push it into the one-touch fitting until it

comes to a stop.

Connector Connecting/Disconnecting• When connecting the connector, insert it straight onto the pins andlock the connector into the square groove in the housing unitconnector clicks.

• When disconnecting the connector, press the connector lever todisengage the lever claw from the square groove. Then pull theconnector straight out.
