Important Information and Warnings
This caution mark indicates a chance of physical damages to the user and/or the product if it is used improperly and/or incorrectly. The damage can be substantial.
CAUTION
●The product is not explosion-proof. Do not use the product in designated areas where explosion-proof specification is required.
●The product is designed for measurement of intended articles and does not feature control functions that ensure security, such as prevention of
accidents.
Operating Precautions
①The applicable media are gases/liquids compatible with 17-4PH（Equivalent to SUS630）. So please be careful about compatibility with applicable media. Use of corrosive fluid may
cause injury and/or malfunction of products. In addition, the product is not explosive-proof. Never use flammable fluid as media.
②Maintain the measuring pressure within the pressure range as stated in specifications. Pressures exceeding the maximum pressure rating may cause product failure.
③Do not press the diaphragm with a hard object. It may cause abnormal output or malfunction.
④Use a stable DC power supply. When using a switching power supply, please do so with the frame ground terminal installed. For inductive loads such as relays and solenoids, put
voltage surge protectors (diodes, varisters, etc.) in the circuit.
⑤Cable wiring should be conducted in the state of power OFF. Shorting the output terminal and power terminal will damage the internal circuit. Please be careful not to wire
incorrectly.
⑥When using the supplied M12 connector cable, tighten fitting by hand（Tightening torque：0.6［N・m］）after fully inserting the connector. If the tightening and inserting is inadequate,
the product may fail to meet the specified IP. In addition, the use of pliers may cause damage to the fitting.
⑦In the insertion and removal of the connector, please check the direction of key slot and do so with the product and connector grabbed tightly. Inadequate insertion and/or removal of
the connector may cause product failure.
⑧Do not rotate the connector portion of the cable. It may cause the sensor and connector damage.
⑨Be careful not to let water contact the periphery of the connector. It may cause damage and leakage and entering the interior.
⑩Please note that bending the connector cable at the near end part may lower the waterproof function and cause damage to the product.
⑪In piping, please do so with the hexagonal portion of the fitting grabbed tightly. Tightening by grabbing only case or connector may cause damage.
⑫Be careful about the possibility that the medium may become frozen. The freezing of the medium in the pressure port can cause damage.
Maintenance Precautions
①Make sure the product operates normally before using. Unexpected event may cause product failure and affect its basic function.
②Do not disassemble or modify the product. Unauthorized disassembly or modification may result in a malfunction. The product warranty does not cover failures caused by
disassembly and/or modification of the product.
③Stains on the product should be wiped off with a cloth immersed in a neutral detergent diluted water. Dry it with a soft cloth after they are wiped off. At this time, be careful
not to allow the neutral detergent solution to enter the inside of the product.
ꢀInfiltration of the neutral detergent solution may cause product failure.
④M12 connector is compliant to IEC61076-2-101.
ꢀIf you would like to use cable other than the supplied cable, please make sure the cable is indeed in compliance with the proper standard. Some cables don’t meet IP standard, so
please check it before using.
