Safety Precautions
zThis product is intended for use with industrial machines, test and measuring
equipment. (It is not designed for use with medical equipment and nuclear energy.)
zThis 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.
zThis 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.
zBe 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, regardlessthe length.
zThis 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 electricshock by operating personnel.
zAll precautions described in this manual should be taken to avoid damage to the
instrument or equipment.
zAll wiring must be in accordance with local codes and regulations.
zTo 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.
zPrevent metal fragments or lead wire scraps from falling inside instrument case to
avoid electric shock, fire or malfunction.
zTighten each terminal screw to the specified torque found in the manual to avoid
electric shock, fire or malfunction.
zFor proper operation of this instrument, provide adequate ventilation for heat
dispensation.
zDo not connect wires to unused terminals as this will interfere with proper
operation of the instrument.
zTurn off the power supply before cleaning the instrument.
zDo 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.
zTo avoid damage to instrument display, do not rub with an abrasive material or
push front panel with a hard object.
zDo not connect modular connectors to telephone line.

1. MOUNTING
1.1 Mounting Cautions
(1) This instrument is intended to be used under the following environmental
conditions. (IEC61010-1) [OVERVOLTAGECATEGORYII,POLLUTIONDEGREE2]
(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/m3dry 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 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.

Mounting procedures
1. Pull down the mounting bracket at the bottom of the instrument (A). Attach the
hooks on the top of the instrument to the DIN rail and push the lower section into
place on the DIN rail (B).
2. Slide the mounting bracket up to secure the instrument to the DIN rail (C).
Removal procedures
Pull down a mounting bracket with a blade screwdriver (A). Lift the instrument from
bottom, and take it off (B).
1.4 Panel Mounting
Mounting procedures
1. Pull down the mounting bracket (A) until locked and that a mounting hole appears.
2. Prepare one mounting bracket per instrument (B) sold separately (KSRX-55) and
then insert it in the rear of the terminal board at top of the instrument until locked
but a mounting hole does not disappear.
3. Mount each module directly on the panel with screws which are inserted in the
mounting holes of the top and bottom mounting brackets.
Recommended tightening torque: 0.3 N⋅m (3 kgf⋅cm)
The customer needs to provide the M3 size screws. Select the screwlength
that matches the mounting panel.

2. WIRING
2.1 Wiring Cautions
•To avoid noise induction, keep communication signal wire away from instrument
power line, load lines and power linesof other electric equipment.
•If there is electrical noise in the vicinity of the instrument that could affect
operation, use a noise filter.
−Shorten the distance between the twisted power supply wire pitches to
achieve the most effective noise reduction.
−Always install the noise filter on a grounded panel. Minimize the wiring
distance between the noise filter output and the instrument power supply
terminals to achieve the most effective noise reduction.
−Do not connect fuses or switches to the noise filter output wiring as this will
reduce the effectiveness of the noise filter.
•Power supply wiring must be twisted and have a low voltage drop.
•For an instrument with 24 V power supply, supply power from a SELVcircuit.
•A suitable power supplyshould be considered in end-use equipment. The power
supply must be in compliance with a limited-energycircuits (maximum available
current of 8 A).
•Use the solderless terminal appropriate to the screw size (M3).
•Make sure that the any wiring such as solderless terminal is not in contact with
the adjoining terminals.

(Server)
The data request side (such as computer) is called Client and the data
response (supply) side (COM-JL) is called Server.
Basically, one Client corresponds to one Server (COM-JL) (i.e. one to one).
However, one Client can communicate with two or more Servers
depending on the program on the Client side, but two or more Clients
cannot communicate with one Server.
