WARNING

CAUTION

: This mark indicates precautions that must be taken if there is danger of electric

shock, fire, etc., which could result in loss of life or injury.

: This mark indicates that if these precautions and operating procedures are not

taken, damage to the instrument may result.

: This mark indicates that all precautions should be taken for safe usage.

: This mark indicates important information on installation, handling and operating

procedures.

: This mark indicates supplemental information on installation, handling and

operating procedures.

: This mark indicates where additional information may be located.

WARNING

 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.

CAUTION

 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.  All wiring must be completed before power is turned on to prevent electric shock,

instrument failure, or incorrect action. The power must be turned off before repairing work for input break and output failure including replacement of sensor, contactor or SSR, and all wiring must be completed before power is turned on again.

 To prevent instrument damage or failure, protect the power line and the input/output lines

from high currents with a protection device such as fuse, circuit breaker, etc.

 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.

 For proper operation of this instrument, provide adequate ventilation for heat dispensation.  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.  Do not use a volatile solvent such as paint thinner to clean the instrument. Deformation or

discoloration will occur. Use a soft, dry cloth to remove stains from the instrument.

 To avoid damage to instrument display, do not rub with an abrasive material or push front

panel with a hard object.

 Do not connect modular connectors to telephone line.

NOTICE

 This manual assumes that the reader has a fundamental knowledge of the principles of electricity,

process control, computer technology and communications.

 The figures, diagrams and numeric values used in this manual are only for purpose of illustration.  RKC is not responsible for any damage or injury that is caused as a result of using this instrument,

instrument failure or indirect damage.

 Periodic maintenance is required for safe and proper operation of this instrument. Some

components have a limited service life, or characteristics that change over time.

 Every effort has been made to ensure accuracy of all information contained herein. RKC makes no

warranty expressed or implied, with respect to the accuracy of the information. The information in this manual is subject to change without prior notice.
