Safety precautions
WARNING
!
 To prevent injury to persons, damage to the instrument and the equipment,
a suitable external protection device shall be required.
 All wiring must be completed before power is turned on to prevent electric
shock, fire or damage to the instrument and the equipment.
 This instrument must be used in accordance with the specifications to
prevent fire or damage to the instrument and the 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 may
occur and warranty is void under these conditions.
CAUTION
 This product is intended for use with industrial machines, test and measuring equipment.
(It is not designed for use with medical equipment and nuclear energy plant.)
 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 additional 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 to operating personnel.
 All precautions described in this manual should be taken to avoid damage to the
instrument or equipment.
 If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
 All wiring must be in accordance with local codes and regulations.
 To prevent instrument damage as a result of failure, protect the power line and the
input/output lines from high currents with a suitable overcurrent protection device with
adequate breaking capacity such as a fuse, circuit breaker, etc.
 A malfunction in this product may occasionally make control operations impossible or
prevent alarm outputs, resulting in a possible hazard. Take appropriate measures in the
end use to prevent hazards in the event of malfunction.
 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 dissipation.
 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 may occur. Use a soft, dry cloth to remove stains from the instrument.
 To avoid damage to the instrument display, do not rub with an abrasive material or push
the front panel with a hard object.
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 explanation
purpose.
 RKC is not responsible for any damage or injury that is caused as a result of using this
instrument, instrument failure or indirect damage.
 RKC is not responsible for any damage and/or injury resulting from the use of instruments
made by imitating this instrument.
 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

2. MOUNTING
WARNING
!
To prevent electric shock or instrument failure, always turn off the
power before mounting or removing the instrument.
2.1 Mounting Cautions
(1) This instrument is intended to be used under the following environmental conditions.
(IEC 61010-1) [OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2]
(2) Use this instrument within the following environment conditions:
 Allowable ambient temperature: 10 to 50 C
 Allowable ambient humidity:
5 to 95 %RH
(Absolute humidity: MAX. W. C 29.3 g/m 3 dry air at 101.3 kPa)
 Installation environment conditions: Indoor use
Altitude up to 2000 m
(3) Avoid the following conditions when selecting the mounting location:
 Rapid changes in ambient temperature which may cause condensation.
 Corrosive or inflammable gases.
 Direct vibration or shock to the mainframe.
 Water, oil, chemicals, vapor or steam splashes.
 Excessive dust, salt or iron particles.
 Excessive induction noise, static electricity, magnetic fields or noise.
 Direct air flow from an air conditioner.
 Exposure to direct sunlight.
 Excessive heat accumulation.
(4) Mount this instrument in the panel considering the following conditions:
 Ensure at least 50 mm space on top and bottom of the instrument for maintenance and
environmental reasons.
 Do not mount this instrument directly above the equipment that generates large amount of
heat (heaters, transformers, semi-conductor functional devices, large-wattage resistors).
 If the ambient temperature rises above 50 C, cool this instrument with a forced air fan,
cooler, etc. Cooled air should not blow directly on this instrument.
 In order to improve safety and the immunity to withstand noise, mount this instrument as
far away as possible from high voltage equipment, power lines, and rotating machinery.
High voltage equipment: Do not mount within the same panel.
Power lines: Separate at least 200 mm.
Rotating machinery: Separate as far as possible.
(5) If this instrument is permanently connected to equipment, it is important to include a
switch or circuit-breaker into the installation. This should be in close proximity to the
equipment and within easy reach of the operator. It should be marked as the
disconnecting device for the equipment.
