3.2 Mounting to the Panel
3.2.1 Procedure for Mounting to the Panel
1) Assemble themounting bracket refer to Fig.3.2.
2) Fitin this instrumentthrough the frontof the panel.
3) Fit the claws of the mounting bracket into the square holes in the top and bottom surfaces of the
case.
4) Tighten the screw of the mounting bracket with a screwdriver to attach it to the panel. When the
mounting unit does not move back and forth anymore, tighten a screwby 180 ﾟ.
Fig. 3.2 Mounting bracket
[Note]
If itis tightened with an excessiveforce, thecase maybedistortedand themounting bracket maybe
deformed. An adequatetightening torque is about 0.2 to 0.3 N･m (2～3kgf・cm).
WARNING
Do not install the instrument in a place exposed to a combustible, explosive, or corrosive gas (SO2, H2S,
etc.).
CAUTION
Install the instrumentin the followingplaces
・Aplacefree from where humidityoftenchanges.
・Aplace of normaltemperature (25℃orso).
・Aplace exposed to as little mechanical vibrations as possible.
・Aplace with as little dusts as possible.
・Aplace affectedbythe electromagnetic field as little aspossible.
・Aplace not directlyexposedto high radiant heat.
・Aplace where the altitude is up to 2000m.
・Humidity has an effecton the chart paperand ink. Use theinstrumentin a humidityrangeof 20 to
80%RH(60%RH is optimum).
・This instrument needs the inside installation.
Mountingto the Panel
・Asteel plate notthinner than 1.2mm is recommendedas a mounting panel.
・The maximum thickness of the mountingpanel is 7mm.
Inclination
・Install the instrument horizontally.
・The instrument should be installed so that its inclination should be 0゜at the front and within 30゜at the
rear.
Assemble in such a manner
that the screw nose will be
almost aligned with the plate
surface.

WARNING
①In order to prevent an electric shock, be sure to provide protective grounding prior to turning on the
instrument.
②Do not cut a protective grounding conductor or disconnect protective grounding.
③Make surethat the supplyvoltage fortheinstrumentconforms to thevoltage of the supplysource.
④Attach a transparent protectivecover prior to turning on the POWER of the instrument.
⑤Any interruption of the protective conductor inside or outside the apparatus or disconnection of the
protective grounding terminal is likely to makethe apparatus dangerous under some fault conditions.
Intentional interruption is prohibited.

4.1.3 Wiring Procedure
1) Put your fingers on the left and right (both sides) hooks of the transparent protective cover on the
power sourceterminal block. Pushing them inside, take out the cover to this side.
2) Connect the power source electric wire refer to Fig. 4.2. Connect the protective grounding to the
terminal. Connect the non-grounding side of the power source to "L" terminal. Connect the
grounding side to the "N" terminal.
3) Put back the transparent protective cover.
4) Make surethat protective grounding is properly provided.

CAUTION
①As an electric wire for the power source,use a 600 V vinyl insulated wire (IEC60227-3)orits
equivalentor above.
②Attach a round press-fitting terminalwith insulated sleeve(for M3.5) to the end of theelectric wire.
③Connect a protective grounding (resistance:100Ωor lower, a minimum diameter of a grounding
conductor:1.6mm) totheprotectivegroundingterminal.
④If other instrument shares the protective grounding conductor, there maybe aneffect caused by
noise comingfrom the groundingconductor. It is recommendednot to share it with other instrument.
⑤In order to comply with therequirements of safetystandard EN61010-1, therecorder shall have one
of thefollowing as a disconnecting device, fitted within easy reachof the operator, andlabeled as the
disconnecting device.
ａ．Aswitch or circuit breaker which complies withthe requirements of IEC60947-1,IEC60947-3.
ｂ．Aseparable coupler which canbe disconnected without the use of a tool.
ｃ．Aseparable plug, without alockingdevice, to mate with a socket outlet inthe building.
⑥This product has designedto conform to EN61010-1 installation CategoryⅡand pollution
degree 2.
⑦Pleaseuse the mainpower supply bythe change within10% of theratedvoltage.
⑧Transitional current might flow to the main power supply when the power supplyis turned on.
CAUTION
The transparent protective cover should surelyremove the leftandright (both sides) hooks simultaneously.
If itremoves by turns, there is a possibilitythat it may damage.

4.2 Input Wiring
CAUTION
①Precautions for theinput electric wire
See that no noise is mixed in input wiring. For input wiring, it is recommendedto use a shielding
wire or twisted wire effective for noise.
In case of thermocouple input,connect a thermocouple wiredirectly or use a compensatinglead
wire. It is recommendedto use a shielded input line.
In case of resistance temperaturedetector input, dispersion of 3-wire line resistance shouldbe
less than the below mentioned values. It is recommended to usea shielded input line.
ForPt100,JPt 100 ；50mΩmax.
Whenitis likelyto beaffectedbyinductionnoise, particularlywhen wiringnearthehigh-frequency
power source, it is recommended touse a shielded twisted wire.
Attacharound press-fitting terminal withinsulatedsleeve(forM3.5)totheendof theelectric wire.
②Precautions forwiring
The wiring between the instrument and measurementpoint should be kept away from the power
circuit(25V or higher circuitor DO circuit).
Short-circuit unused input terminals. (Short-circuit between "＋"and"－" in case of mV, V, or
thermocouple input, andshort-circuitamongA, B, and B in case of resistance temperature
detector input.)
Groundthe shield of connecting wire.
