3.2 Mounting to the Panel
3.2.1 Procedure for Mounting to the Panel
1) Assemble the mounting bracket refer to Fig.3.2.
2) Fitin this instrument throughthefront of 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 andforth anymore, tighten a screwby180゜.

Assembleinsuchamannerthat
the screw nose will be almost
aligned with theplate surface.

MountingClaw
［Note］
If itis tightened with an excessive force, the case maybe distortedandthe mounting bracketmaybe
deformed. An adequatetighteningtorque isabout 0.2to 0.3N･m (2～3㎏ｆ・㎝).
WARNING
Do not install the instrument in a place exposed to a combustible, explosive, or corrosivegas (SO2, H2S,
etc.).
CAUTION
Installthe instrumentin the followingplaces
・Aplacefree from wherehumidityoften changes.
・Aplace of normal temperature (25℃orso).
・Aplace exposed to as little mechanical vibrations as possible.
・Aplace with as little dusts as possible.
・Aplace affected by theelectromagnetic field as little as possible.
・Aplace not directlyexposed to high radiant heat.
・Aplace where the altitude is up to 2000m.
・Humidity hasan effect on the chart paper and ink. Use theinstrumentin a humidity range of 20 to
80%RH(60%RHis optimum).
・This instrument needs the inside installation.
Mountingto the Panel
・Asteel plate notthinner than 1.2mm is recommended as a mountingpanel.
・Themaximum thickness of the mounting panel is 7mm.
Inclination
・Install the instrument horizontally.
The instrument should be installed so that its inclinationshould be 0゜at the frontand within30゜at the rear.

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 source terminalblock. Pushing them inside, take out the cover to this side.
2) Connect the power sourceelectric wire refer to Fig. 4.2. Connect theprotective groundingto the
terminal. Connect the non-grounding side of the power source to "L" terminal. Connect the
grounding side tothe "N" terminal.
3) Put back thetransparent protectivecover.
4) Make sure thatprotective grounding is properly provided.
Fig. 4.2 Power source Terminal block
CAUTION
①As an electric wire for the power source, use a 600 V vinyl insulated wire (IEC60227-3) or its
equivalentorabove.
②Attach a round press-fitting terminal with 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) totheprotectivegrounding terminal.
④If other instrument shares the protective grounding conductor, there may be an effect caused by
noise coming from thegroundingconductor. It is recommended not to shareit withother instrument.
⑤In order to comply with the requirements of safetystandard EN61010-1, the recorder shall have one
of the following as a disconnecting device, fitted within easy reachof the operator, andlabeledas the
disconnecting device.
a．Aswitch or circuit breakerwhich complies withtherequirements of IEC60947-1,IEC60947-3.
b．Aseparable coupler whichcanbe disconnected without the use of a tool.
c．Aseparable plug, without a lockingdevice, to mate with a socket outlet in the building.
⑥This product has been designed to conform to EN61010-1 installation category Ⅱand pollution
degree 2.
⑦Please use themain power supplyby the change within 10% of the rated voltage.
⑧Transitional current might flow to the main power supplywhen the power supply is turned on.

CAUTION
The transparent protective cover shouldsurely remove the left andright (both sides) hooks simultaneously.
If itremoves byturns, there is apossibility that 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 recommended to use a shielding wire or
twisted wire effective for noise.
・Incase of thermocouple input, connect a thermocouple wire directlyor use a compensating lead
wire. It is recommended to useashielded input line.
・Incase of resistance temperature detector input, dispersion of 3-wire line resistance should be less
than the below mentioned values. It is recommendedto use a shielded input line.
ForPt100,JPt 100 ；50mΩmax.
・Whenit is likelyto be affectedbyinduction noise, particularly when wiring near the high-frequency
powersource, it is recommended to use ashielded twisted wire.
・Attach a round press-fitting terminal with insulated sleeve (for M3.5) to theendof the electric wire.
②Precautions forwiring
・The wiring between the instrumentand measurement point should be keptaway from the power circuit
(25V or higher circuit or DO circuit).
・Short-circuit unused input terminals.(Short-circuit between "＋" and "－" in case of mV,V, or
thermocouple input, and short-circuitamongA, B, and B in case of resistance temperature detector
input.)
・Groundtheshield of connecting wire.
