■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.

Product specifications
•
The direct current power supply to be used should be UL approved as follows:
Circuit (of Class 2) which is of maximum 30 Vrms (42.4 V peak), with UL1310 Class 2 power supply unit or UL1585
Class 2 transformer.
•
The product is a UL approved product only if it has a
•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)
•A ceramic diaphragm is used as the pressure sensor for this product. The ceramic diaphragm can be
damaged by overpressure from hydraulic shock. This can be the result of several situations such as
system fill or sudden changes in flow sometimes called "water hammer".
If there is a possibility of the case above, reduce the diameter of the piping to the pressure switch, or
introduce an orifice in the piping.
