Mounting and Installation
Piping
SUP port (supply port) and OUT port (detection port)
•Use the correct tightening torque. (Appropriate tightening torque (Rc1/8 • G1/8): 7 to 9 Nm)
•For ø6 one-touch fitting, use tube with O.D. 6 mm, and I.D. 4 mm.
•For ø4 one-touch fitting, use tube with O.D. 4 mm, and I.D. 2.5 mm.
Atmospheric vent port
•Connect tubing (sold separately) to the atmospheric
vent port if there is a possibility that the port could be
blocked by water or dust.
•Recommended tube is TU0425 (material: polyurethane,
O.D. ø4, I.D. ø2.5) made by SMC.
•The other end of the air tubing should be routed to a
safe place to prevent it from being exposed to water
or dust.
•Ensure the tubing has no sharp bends.
Installation
DIN rail
•Hook the claw part 1 to the DIN rail. •Push the claw part 2 down until it clicks.
Claw1
Claw2
Bracket
•Mount the bracket to the product using the mounting screws (3 pcs.).
•The tightening torque of the mounting screw must be 0.45 Nm ±10%.
•When the product is mounted using the bracket, fix with M5 screws (2 pcs.) or equivalent.
•Bracket thickness is approx. 1.6 mm.
•Refer to the SMC website (URL http://www.smcworld.com) for mounting hole dimensions.
Wiring
Mounting and removal of connector
•Align the body connector key and the cable connector key
groove to insert vertically.
•Turn the knurled part of the cable sideconnector
clockwise.
•Connection is complete when the knurled part is fully
tightened.
Check that the connection is not loose.
