: 

This mark indicates where additional information 

may be located. 

An external protection device must be installed if failure 

of this instrument could result in damage to the 

instrument, equipment or injury to personnel. 

All wiring must be completed before power is turned on 

to prevent electric shock, fire or damage to instrument 

and equipment. 

This instrument must be used in accordance with the 

specifications to prevent fire or damage to instrument 

and equipment.   

This instrument is not intended for use in locations 

subject to flammable or explosive gases. 

Do not touch high-voltage connections such as power 

supply terminals, etc. to avoid electric shock. 

RKC is not responsible if this instrument is repaired, 

modified or disassembled by other than 

factory-approved personnel. Malfunction can occur and 

warranty is void under these conditions. 

This is a Class A instrument. In a domestic environment, this 

instrument may cause radio interference, in which case the user 

may be required to take adequate measures. 

This instrument is protected from electric shock by reinforced 

insulation. Provide reinforced insulation between the wire for the 

input signal and the wires for instrument power supply, source of 

power and loads. 

Be sure to provide an appropriate surge control circuit respectively 

for the following: 

- If input/output or signal lines within the building are longer than 

30 meters. 

- If input/output or signal lines leave the building, regardless the 

length. 

This instrument is designed for installation in an enclosed 

instrumentation panel. All high-voltage connections such as power 

supply terminals must be enclosed in the instrumentation panel to 

avoid electric shock by operating personnel.   

All precautions described in this manual should be taken to avoid 

damage to the instrument or equipment. 

All wiring must be in accordance with local codes and regulations. 

To prevent instrument damage of failure, protect the power line 

and the input/output lines from high currents with a protection 

device such as fuse, circuit breaker, etc. 

For an instrument with 24 V power supply, supply power from a 

SELV circuit. 

Prevent metal fragments or lead wire scraps from falling inside 

instrument case to avoid electric shock, fire or malfunction. 

Tighten each terminal screw to the specified torque found in the 

manual to avoid electric shock, fire or malfunction. 

Do not connect wires to unused terminals as this will interfere with 

proper operation of the instrument. 

Turn off the power supply before cleaning the instrument. 

The resin adhered to this instrument should be cleaned to dry 

cloth with a clean while the resin is still hardened, be careful of 

burns. 

Tools such as wire wheels or abrasive cloths should never be 

used to clean the process diaphragm. 

Do not apply impact to nor drop this product. If so, its damage or 

fault may result. 

As precise parts are incorporated, do not give any shock and 

handle carefully during transportation and installation. Take great 

care not to scratch the diaphragm. 

Do not wipe or rub the nameplate on the outer case of the resin 

pressure sensor with a cloth moistened with an organic solvent, or 

a glove. If so, the printed section may be erased. 

This product uses stainless steel, aluminum, and fluororesin (O-rings  

and leadwire covering materials). When disposing of each part used  

for this product, always follows the procedure for disposing of 

industrial wastes stipulated by the respective local community.
