WARNING
l Use the Correct Power Supply
Ensure that the source voltage matches the voltage of the power
supply before turning ON the power.
l Connect the Protective Grounding Terminal
Make sure to connect the protective grounding to prevent
electric shock before turning ON the power.
l Do Not Impair the Protective Grounding
Never cut off the internal or external protective grounding wire
or disconnect the wiring of the protective grounding terminal.
Doing so invalidates the protective functions of the instrument
and poses a potential shock hazard.
l Do Not Operate with Defective Protective Grounding
Do not operate the instrument if the protective grounding might
be defective. Also, make sure to check them before operation.
l Do Not Operate in an Explosive Atmosphere

2. Installation
n Installation Location
Install the FX indoors in an environment that meets the following conditions:
• Instrumentation Panel
The FX is designed to be installed in an instrumentation panel.
• Well-Ventilated Location
To prevent overheating, install the FX in a well-ventilated location. For the panel
cut dimensions when arranging multiple FXs, see “External Dimensions and Panel
Cutout Dimensions.” When other instruments are installed next to the FX, follow
the panel cut dimensions to provide adequate space around the FX.
• Minimal Mechanical Vibrations
Install the FX in a location that has minimal mechanical vibrations. Installing the FX
in a location that is subject to large levels of mechanical vibration will not only put
added stress on its components, it may also impede ordinary measurement.
• Level Location
Install the FX in a level location so that it is not slanted to the left or the right (how-
ever, the FX can be inclined up to 30 degrees backward for panel mounting).
Note
Condensation may form when moving the FX from an environment whose temperature or
humidity is low to an environment whose temperature or humidity is high, or when there
is a sudden change in temperature. Temperature or humidity changes may also result in
thermocouple measurement errors. In these kinds of circumstances, let the FX adjust to
the new environment for at least an hour before using it.
Do not install the FX in the following places.
• Outdoors
• In Direct Sunlight or Near Heat Sources
Install the FX in a place that is near room temperature (23°C) and that is not sub-
ject to large temperature fluctuations. Placing the FX in direct sunlight or near heat
sources can cause adverse effects on the internal circuitry.
• Where an Excessive Amount of Soot, Steam, Moisture, Dust, or Corrosive
Gases Are Present
Soot, steam, moisture, dust, and corrosive gases will adversely affect the FX.
Avoid installing the FX in such locations.
• Near Strong Magnetic Field Sources
Do not bring magnets or instruments that produce electromagnetic fields close to the
FX. Operating the FX near strong magnetic fields can cause measurement errors.
• Where the Display Is Difficult to See
The FX uses an LCD screen, so it is difficult to view the display from an extreme
angle. Install the FX so that the user can view the display directly from the front.
n Installation Procedure
Use a steel panel that is 2 mm to 26 mm thick.
1) Insert the FX through the front of the panel.
2) Mount the FX to the panel using the included mounting brackets as shown in the figure below.
• Use two mounting brackets to support the top and bottom or the left and right sides of the
case (remove the stickers that are covering the holes before you attach the brackets).
• Follow the procedure below to mount the FX to the panel.
• First, attach the two mounting brackets and temporarily tighten the mounting screws.
• Next, fix the FX in place by tightening the mounting screws with the appropriate torque.
When the FX is approximately perpendicular to the panel, press the mounting brackets
so that they are in contact with the case, and fully tighten the mounting screws.
• Tighten the mounting bracket screws until you hear clicks.
CAUTION
l Using more than the appropriate torque to tighten the screws
can deform the case or damage the brackets.
l Be sure not to insert foreign objects or tools into the case
through the mounting bracket holes.
l Do not touch the screw at the top of the mounting bracket
(A). Loosening or tightening this screw may cause the FX to
malfunction.

3. Wiring
n Input Signal Wiring
WARNING
To prevent electric shock while wiring, make sure that the power
supply is turned off.
CAUTION
l Applying a strong tension to the input and output signal cables
connected to the FX may damage the cables or the FX terminals.
To avoid applying tension directly to the terminals, fix all cables
to the rear of the mounting panel.
l To prevent fire, use signal cables with a temperature rating of 70°C
or more.
l Do not apply voltages that exceed the following values to the
input terminals. Doing so may damage the FX.
• Maximum input voltage: ±60 VDC
• Maximum common mode voltage: ±60 VDC (under
measurement category II conditions)
l The FX is an installation category II product.
Precautions to Be Taken While Wiring
Take the following precautions when wiring the input signal cables.
When using a screw terminal, we recommend that you use a crimp-on lug with an
insulation sleeve (designed for 3 mm screws).
Take measures to prevent noise from entering the measurement circuit.
• Move the measurement circuit away from the power cable (power circuit) and ground circuit.
• Ideally, the object being measured should not generate noise. However, if this is
unavoidable, isolate the measurement circuit from the object. Also, ground the ob-
ject being measured.
• Shielded wires should be used to minimize the noise caused by electrostatic induc-
tion. Connect the shield to the ground terminal of the FX as necessary (make sure
you are not grounding at two points).
• To minimize noise caused by electromagnetic induction, twist the measurement
circuit wires at short, equal intervals.
• Make sure to earth ground the protective ground terminal through minimum resis-
tance (less than 100 Ω).
When using internal reference junction compensation on the thermocouple input,
take measures to stabilize the temperature at the input terminal.
• Always use the terminal cover.
• Do not use thick wires which may cause large heat dissipation (we recommend a
cross sectional area of 0.5 mm 2 or less).
• Make sure that the ambient temperature remains reasonably stable. Large tem-
perature fluctuations can occur if a nearby fan turns on or off.
Connecting the input wires in parallel with other devices can cause signal degradation,
affecting all connected devices. If you need to make a parallel connection, then
• Turn the burnout detection function off.
• Ground the instruments to the same point.
• Do not turn other instruments on or off during operation. This can have adverse ef-
fects on the other instruments.
• RTDs cannot be wired in parallel.

For TC input, use shielded compensating lead wires for wiring.
For RTD input, lead wire resistance per wire of 10 Ω or less. Make the resistances of
the three wires equal.
For DCA input, example: for 4 to 20 mA input, use a shunt resistor of 250 Ω ± 0.1%.
