• 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.

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 80°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%.

on models with the /N2 option (3 leg isolated RTD).

Optional Terminal Wiring
WARNING
l
To prevent electric shock while wiring, make sure that the power
supply is turned off.
l
If a voltage of more than 30 VAC or 60 VDC is to be applied to the
output terminals, use ring-tongue crimp-on lugs with insulation
sleeves on all terminals to prevent the signal cables from
slipping out when the screws become loose. Furthermore, use
double-insulated cables (dielectric strength of 3000 VAC or more)
for the signal cables on which a voltage of 30 VAC or 60 VDC
or more is to be applied. For all other signal cables, use basic
insulated cables (dielectric strength of 1500 VAC). To prevent
electric shock, attach the terminal cover after wiring and make
sure not to touch the terminals.
CAUTION
l
Use the following circuit voltages for the connection to the
alarm/FAIL/status output terminal.
• When the connection is to Mains Circuits (primary power
supply circuits): 150 V or less
• When the connection is to circuits derived from Mains
Circuits (secondary power supply circuits): 250 V or less
(Keep the Mains Circuit voltage at 300 V or less, and use
an isolation transformer.)
l
To prevent fire, use signal cables with a temperature rating of 70°C or more.
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
Do not short the transmitter power supply output terminal or apply
external voltage to it. Doing so may damage the instrument.
l
When using the transmitter power supply output terminal, do not
use current that is equal to or greater than the maximum output
current (25 mADC). Doing so may damage the instrument.
Precautions to Be Taken While Wiring
We recommend that you use crimp-on lugs (designed for 3 mm screws) with
insulation sleeves to connect to the optional terminals.
The following figures show the terminal positions for each option when only that
option is installed. Even if you have installed a number of options, the individual
terminal positions of the options do not change (except for the case where you have
installed both the /TPS2 and /A1 options; in this case, the /A1 terminal positions are
different).
