■
Mounting
Warning
1)
Tighten to the specified tightening torque.
If the tightening torque is exceeded, the product, the mounting screws, brackets and the pressure switch
can be broken. Insufficient torque can cause displacement of the product and the pressure switch from
each proper position and loosening of the mounting screws.
2)
Hold the product itself when handling.
Do not pull the M8 connector cable strongly or lift up the product by holding this cable. It can cause the
malfunction of the product.
■
Wiring
Warning
1)
Do not perform wiring while the power is on.
Otherwise damage to the solenoid valve or the internal parts of the pressure switch/sensor can result,
causing malfunction.
2)
Never disassemble the M8 connector cable or make any modifications including additional machining.
Doing so may cause human injury and/or an accident.
Caution
1) Avoid repeated bending, tensioning or external force to the M8 connector cable.
■
Piping
Caution
1) Preparation before piping
Before piping, perform air blow (flushing) or cleaning to remove any cutting chips, cutting oil, dust, etc. from
the piping.
2) Installation of tubing
・
Cut the tubing perpendicularly, being careful not to damage the outside surface. Use an SMC tube cutter TK-
