Caution for EC Directive
The analog special adapters have been found to be compliant to the European
standards in the aforesaid manual and directive. However, for the very best per-
formance 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 induced
errors not exc10%/-10% in very heavy industrial areas.
However, Mitsubishi Electric suggest that if adequate EMC precautions are fol-
lowed with general good EMC practice for the users complete control system,
users should expect normal errors 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. When terminating the shield at Earth
- ensure that no earth loops are accidentally created.
•
When reading analog values, EMC induced errors can be smoothed out by
averaging the readings. This can be achieved either through functions on the
analog special adapters or through a users program in the FX
3U
Series PLC
main unit.

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.

WIRING
PRECAUTIONS
•
Cut off all phases of power source externally, before installation or wiring
work in order to avoid electric shock or damage of product.
WIRING
PRECAUTIONS
•
Never let cutting chips and wire chips enter the ventilation slits of this product
or PLC when performing wiring.
Otherwise, fire, failure or malfunction may occur.
•
Make sure to observe the precautions below in order to prevent any damage
to a machine or any accident which might be caused by abnormal data
written in the PLC due to the influence of noise:
1) Do not lay close or bundle with the main circuit, high-voltage power line,
or load line.
Otherwise effects of noise or surge induction are likely to take place.
Keep a safe distance of more than 100 mm (3.94") from the above when
wiring.
2) Ground the shield wire or shield of a shielded cable at one point on the
PLC. However, do not ground at the same point as high voltage lines.
•
Observe the following items to wire the lines to the European terminal board.
Failing to do so may cause electric shock, short circuit, disconnection, or
damage of the product.
- The disposal size of the cable end should follow the dimensions described
in this manual.
- Tighten to a torque should follow the torque described in this manual.
- Twist the end of strands and make sure there is no loose wires.
- Do not solder-plate the electric wire ends.
- Connect only the electric wires of regulation size.
- Fix the electric wires so that the terminal block and connected parts of
electric wires are not directly stressed.
•
Properly perform wiring to the terminal block of the FX
3U
Series PLC
following the precautions below in order to prevent electrical shock, short-
circuit, breakage of wire, or damage to the product:
- The disposal size of the cable end should follow the dimensions described
in this manual.
- Tighten to a torque should follow the torque described in this manual.
