Caution for EC Directive
The FX -4AD have been found to be compliant to the European standards in

Electric would like to make the following points;

As analog devices are sensitive by nature, their use should be considered care-
fully. For users of proprietary cables (integral with sensors or actuators), these
users should follow those manufacturers installation requirements.
Mitsubishi Electric recommend that shielded cables should be used. If NO other
EMC protection is provided, then users may experience temporary loss or
accuracy between ±10% in very heavy industrial areas.
However, Mitsubishi Electric suggest that if adequate EMC precautions are fol-
lowed for the users complete control system, users should expect accuracy as
specified in this manual.

3U • Sensitive analog cable should not be laid in the same trunking or cable
conduit as high voltage cabling. Where possible users should run analog
cables separately.
• Good cable shielding should be used. Ground the shield of the twisted
shielded cable at one point on the PLC side.
• When reading analog values, EMC accuracy can be improved out by
averaging the readings. This can be achieved either through functions on the
special function block for analog input or through a users program in the
FX Series PLC main unit.

PRECAUTIONS
• Use the product within the generic environment specifications described in PLC
main unit manual (Hardware Edition).
Never use the product in areas with excessive dust, oily smoke, conductive dusts,
corrosive gas (salt air, Cl , H

impacts, or expose it to high temperature, condensation, or rain and wind.
If the product is used in such conditions, electric shock, fire, malfunctions,
deterioration or damage may occur.
• Do not touch the conductive parts of the product directly.
Doing so may cause device failures or malfunctions.
• Install the product securely using a DIN rail or mounting screws.
• Install the product on a flat surface.
If the mounting surface is rough, undue force will be applied to the PC board,
thereby causing nonconformities.
• When drilling screw holes or wiring, make sure that cutting and wiring debris do
not enter the ventilation slits of the PLC.
Failure to do so may cause fire, equipment failures or malfunctions.
• Be sure to remove the dust proof sheet from the PLC's ventilation slits when
installation work is completed.
Failure to do so may cause fire, equipment failures or malfunctions.
• Connect extension cables securely to their designated connectors.
Loose connections may cause malfunctions.
2.1 Arrangements
The product connects on the right side of an PLC main unit or extension units/blocks
(including special function units/blocks).

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 observe the following precautions in order to prevent
malfunctions under the influence of noise:
1) Do not bundle the power line or twisted shielded cable 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 100mm (3.94") or more away
from the main circuit, high-voltage line, or load line.
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 terminal blocks in accordance with the
following precautions.
Failure to do so may cause electric shock, equipment failures, a short-circuit,
Series PLC or FX 2NC Series PLC extension block,
wire breakage, malfunctions, or damage to the product.
