2.1 Installation Method
1) Remove the top cover (A in the right
figure) or top cover (S) (A’ in the right
figure).
In a 14/24-point type main unit, only
the top cover (A in the right figure) is
provided.
2) Attach the accessory side cover (B in
the right figure).
Attachment of the side cover (B in the
right figure) is not necessary when
installing the FX
3G
-2AD-BD to only
under the top cover (S) of a 40/60-
point type main unit.
3) Make sure the expansion board is in
parallel with the main unit and attach it
to the optional equipment connector.
4) Fix the expansion board to the main
unit using the provided M3 tapping
screws. (2 places)

If the product is used in such conditions, electric shock, fire, malfunctions,
deterioration or damage may occur.
•
When drilling screw holes or wiring, make sure cutting or wire debris does not
enter the ventilation slits.
Failure to do so may cause fire, equipment failures or malfunctions.
•
Do not touch the conductive parts of the product directly.
Doing so may cause device failures or malfunctions.
•
Connect expansion board securely to their designated connectors.
Loose connections may cause malfunctions.

3. Wiring
3.1 Applicable Cable and Terminal Tightening Torque
3.1.1
Terminal block (European type)
1) Wire size
Wiring to analog device should use 20-22 AWG wire.
2) Applicable cable
3) Termination of cable end
Strip the coating of strand wire and twist the cable core before connecting it,
or strip the coating of single wire before connecting it.
An alternative connection is to use a ferrule with insulating sleeve.
When using a stick terminal with insulating sleeve, choose a wire with proper
cable sheath referring to the above outside dimensions, or otherwise, the
wire cannot be inserted easily.
The tightening torque must be 0.22 to 0.25N

WIRING
PRECAUTIONS
•
Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.
WIRING
PRECAUTIONS
•
Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.
•
Make sure to observe the following precautions in order to prevent any
damage to the machinery or accidents due to abnormal data written to the
PLC under the influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main
circuit, high-voltage line or load line.
Otherwise, noise disturbance and/or surge induction are likely to take
place. As a guideline, lay the control line at least 100mm (3.94") or more
away from the main circuit or high-voltage lines.
2) Ground the shield wire or shield of the shielded cable at one point on the
PLC. However, do not use common grounding with heavy electrical
systems.
•
Make sure to properly wire to the European terminal board in accordance
with the following precautions.
Failure to do so may cause electric shock, a short-circuit, wire breakage, or
damage to the product.
- The disposal size of the cable end should be 9mm (0.35").
- Tightening torque should be between 0.22 and 0.25N
•
m.
- Twist the end of strand wire and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires
of unspecified size.
- Affix the electric wires so that neither the terminal block nor the connected
parts are directly stressed.
•
Make sure to properly wire to the FX
3G
Series PLC in accordance with the
following precautions.
Failure to do so may cause electric shock, a short-circuit, wire breakage, or
damage to the product.
- The disposal size of the cable end should follow the dimensions described
in this manual.
- Tightening torque should follow the specifications in this manual.

4) Tool
For tightening the terminal, use a
commercially available small
screwdriver having a straight form that is
not widened toward the end as shown
right.
Caution :
If the diameter of screwdriver grip is too
small, tightening torque will not be able
to be achieved. Use the following recommended screwdriver or an
appropriate replacement (grip diameter: approximately 25mm (0.98")).
3.2 Wiring of Analog Input
→
For the terminal configuration, refer to Section 1.2
*1 Make sure to short-circuit the 'V
+' and 'I
+' terminals when current is
input. (
: input channel number)
3.2.1
Cautions
1) Make sure to short-circuit the 'V
+' and 'VI-' terminals when ch is not used.
2) Use 2-core shielded twisted pair cable for the analog input lines, and
separate the analog input lines from other power lines or inductive lines.
3) The grounding resistance should be 100
Ω
or less.
3.3 Grounding
Grounding should be performed as stated below.
•
The grounding resistance should be 100
Ω
or less.
•
Independent grounding should be performed for best results.
When independent grounding is not performed, perform "shared
grounding" of the following figure.
→
For details, refer to the FX
3G
Series User's
Manual - Hardware Edition.
•
The grounding wire size should be AWG 22-20 (0.3-0.5 mm
2
).
•
The grounding point should be close to the PLC, and all grounding wire
should be as short as possible.
