Caution for EC Directive
The FX
3U
-4DA have been found to be compliant to the European standards in
the aforesaid manual and directive. However, for the very best performance
from what are in fact delicate measuring and controlled output device Mitsubishi
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.
•
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 signal receiving side.
•
Please use FX
3U
-4DA while installed in a shielded enclosure. For the details,
refer to the following manual.

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
2
, H
2
S, SO
2
, or NO
2
), flammable gas, vibration or
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.

3. Wiring
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 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 or high-voltage lines.
2) Ground the twisted shield cable at one point on the signal receiving side.
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,
wire breakage, malfunctions, or damage to the product.
- The disposal size of the cable end should follow the dimensions
described in the manual.
- Tightening torque should follow the specifications in the manual.
- Tighten the screws using a Phillips-head screwdriver No.2 (shaft diameter
6mm (0.24") or less). Make sure that the screwdriver does not touch the
partition part of the terminal block.
1)
2)
A
3.1 Applicable Cable and Terminal Tightening Torque
The size of the terminal screws is M3.
The end disposal of the cable shows below.
Tighten the terminal to a torque of 0.5 to 0.8N
•
m.
Do not tighten terminal screws with a torque outside the abovementioned range.
Failure to do so may cause equipment failures of malfunctions.
•
When one wire is connected to one terminal
