Safety Instructions
Mounting and Installation
Warning
Mounting
Do not disassemble, modify (including changing the printed circuit board) or repair. •Never mount the product in a place where it will be used as a mechanical support.
An injury or failure can result.
•Mount the product so that the fluid flows in the direction indicated by the arrow on the side
of the body.
Do not operate the product outside of the specifications.
Do not use for flammable or harmful fluids.
Installation
Fire, malfunction or damage to the product can result.
Verify the specifications before use.

Do not use the product in a place where static electricity is a problem.
Otherwise it can cause failure or malfunction of the system. Insert
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
•Stop the air supply, exhaust the residual pressure and verify that the air is released before performing
maintenance work
Otherwise an injury can result.

Otherwise electric shock, malfunction or damage to the product can result.
1
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 leakage occurs from parts other than the piping, the product might be faulty.
Disconnect the power supply and stop the fluid supply.
Do not apply fluid under leaking conditions.
Safety cannot be assured in the case of unexpected malfunction.
NOTE
The direct current power supply used should be UL approved as follows.
Circuit (class 2) of maximum 30 Vrms (42.4 V peak) or less, with UL 1310
class 2 power supply unit or UL 1585 class 2 transformer.
The product is a UL approved product only if it has a mark on the body.

•Use a suitable spanner for the appropriate torque. Do not use a spanner 40 cm or
longer.
•If the tightening torque is exceeded, the product can be broken.
If the tightening torque is insufficient, the fitting may become loose.
•Avoid any sealing tape getting inside the flow path.
•Ensure there is no leakage after piping.

Wiring
Connection
•Connections should only be made with the power supply turned off.
•Use a separate route for the product 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.
Connecting/Disconnecting
•When mounting the connector, insert it straight into the socket, holding the lever and
connector body, and push the connector until the lever hooks into the housing, and locks.
•When removing the connector, press down the lever to release the hook from the
