1 Safety Instructions (continued)
■ Do not disassemble, modify (including changing the printed
circuit board) or repair.
An injury or failure can result.
■ Do not operate the product outside of the specifications.
Do not use for flammable or harmful fluids.
Fire, malfunction, or damage to the product can result.
Verify the specifications before use.
■ Do not operate in an atmosphere containing flammable or
explosive gases.
Fire or an explosion can result.
This product is not designed to be explosion proof.
■ Do not use with flammable or highly permeable fluids.
Fire, explosion, damage or corrosion can result.
■ Do not use the product in a place where static electricity is a
problem.
Otherwise it can cause failure or malfunction of the system.
■ If using the product in an interlocking circuit:
•Provide a double interlocking system, for example a mechanical system.
•Check the product regularly for proper operation.
Otherwise malfunction can result, causing an accident.
■ The following instructions must be followed during maintenance:
•Turn off the power supply.
•Ensure the flow is shut off before performing maintenance.
Otherwise an injury can result.
Caution
■Do not touch the terminals and connectors while the power is on.
Otherwise electric shock, malfunction or damage to the product can
result.
■Do not touch the piping or its connected parts when the fluid is at
high temperature.
It may cause burns.
Ensure the piping cools sufficiently before touching.
■After maintenance is complete, perform appropriate functional
inspections and leak tests.
Stop operation if the equipment does not function properly or there is a
leakage of fluid.
When leaks occur from parts other than the piping, the product may be
faulty.
Cut off power supply and stop supplying fluid.
Do not apply fluid at leaking condition.
Safety cannot be assured in the case of unexpected malfunction.

4 Mounting and Installation
Refer to the product catalogue or SMC website ( URL
http://www.smcworld.com) for more detailed information.
4.1 Mounting
• Never mount the product in a location where it will be used as a support.
• Mount the product so that the fluid flows in the direction indicated by the
arrow on the side of the body.
• Check the flow characteristics data for pressure loss and the straight inlet
pipe length effect on accuracy, to determine inlet piping requirements.
• Do not sharply reduce the piping size.
• The piping port and metal part of the body are grounded to DC (-)/ blue.
Note that a power supply with positive ground cannot be used.
4 Mounting and Installation (continued)
• When several sensors are mounted in parallel, do not mount them in the
area where installation is prohibited as shown below.
If the product is mounted in the area where installation is prohibited, the
accuracy will decrease.
4.2 Installation
• Use the product within the specified operating pressure and temperature
range.
• Proof pressure is 2 MPa. Proof pressure could vary according to the fluid
temperature. Check the characteristics data for applying pressure.
Bracket mounting
