■Do not touch the terminals and connectors while the power is on.
Otherwise electric shock, malfunction or damage to the product can result.
■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
○Follow the instructions given below when designing, selecting and handling the product.
●The instructions on design and selection
described below must also be followed.
maintenance, etc.)
Product specifications
Use the specified voltage.
Otherwise failure or malfunction can result.
Do not exceed the specified maximum allowable load.
Otherwise it can cause damage or shorten the lifetime of the Pressure switch.

Design the product to prevent reverse current when the circuit is opened or the product is forced to operate for
operational check.
Reverse current can cause malfunction or damage to the product.
Input data to the Pressure switch is not deleted, even if the power supply is cut off.
(Writing time: 10,000 times, Data duration: 20 years after power off)
Use the clean air.
This can cause operating failure.
If compressed air containing condensate is used, install an air dryer or drain catch before the filter and perform
drainage regularly.
If drainage is not performed regularly and condensate enters the secondary side, it can cause operating failure of
pneumatic equipment.
If regular drainage is difficult, the use of a filter with an auto drain is recommended.
Applicable fluid is air, inert gases and incombustible gases.
Do not use a fluid containing chemicals, synthetic oils including organic solvent, salt and corrosive gases.
Otherwise, damage to the product and malfunction can result.
Check the details of the specifications before using.
Use the specified measurement flow rate and operating pressure.
Otherwise it can cause damage to the pressure switch or inability to measure correctly.
Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
