Mitsubishi Electric FX3U-ENET-L Installation Manual page 2

INSTALLATION
PRECAUTIONS
 Install the unit on a flat surface.
If the mounting surface is rough, undue force will be applied to the PC board,
thereby causing nonconformities.
 Install the product securely using a DIN rail or mounting screws.
 When drilling screw holes or wiring, make sure that cutting or wire debris
dose not enter the ventilation slits.
Failure to do so may cause fire, equipment failures or malfunctions.
 Be sure to remove the dust proof sheet from the PLC's ventilation port 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 Mounting
The FX -ENET-L can be mounted directly using screws or on a DIN rail
3U
(DIN46227).
2.1.1 Direct Mounting
The FX 3U -ENET-L can be mounted with M4 screws by using the direct mounting
holes.
A space of 1 to 2 mm (0.04" to 0.08") between each unit is necessary.
2.1.2 DIN Rail Mounting
The FX 3U -ENET-L can be mounted on a DIN rail (DIN46227, 35 mm width).
1) Fit the upper edge of the DIN rail mounting 1)
groove (fig. A) onto the DIN rail.
2) Push the unit onto the DIN rail.

DESIGN
PRECAUTIONS
 Make sure to include the following safety circuits outside the PLC to ensure
safe system operation even during external power supply problems or PLC
failure.
Otherwise, malfunctions may cause serious accidents.
1)Most importantly, have the following: an emergency stop circuit, a
protection circuit, an interlock circuit for opposite movements (such as
normal vs. reverse rotation), and an interlock circuit (to prevent damage
to the equipment at the upper and lower positioning limits).
2)Note that when the PLC main unit detects an error such as a watchdog
timer error, during self diagnosis, all outputs are turned off. Also, when an
error that cannot be detected by the PLC main unit occurs in an input/
output control block, output control may be disabled.
External circuits and mechanisms should be designed to ensure safe
machinery operation in such cases.
DESIGN
PRECAUTIONS
 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 likey 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 a shielded cable. However, do not ground
them at the same point as the high-voltage lines.
 Install module so that excessive force will not be applied to the unit or cables.
Failure to do so may result in wire damage/breakage or PLC failure.
STARTUP AND
MAINTENANCE
PRECAUTIONS
 Do not touch any terminals or connector while the PLC's power is on.
Doing so may cause electrical shock or malfunctions.
 Before cleaning or retightening screws, externally cut off all phases of the power
supply.
Failure to do so may cause malfunction or failure of this unit.
When the screws are tightened insufficiently, they may fall out and cause a short-
circuit or malfunction. When tightened too much, the screws or the unit may be
damaged, resulting in short-circuit, or malfunction.
 When controlling the PLC (especially when changing data, the program or
changing the operating conditions) during operation, ensure that it is safe to do
so.
STARTUP AND
MAINTENANCE
2)
PRECAUTIONS
 Do not disassemble or modify the unit.
Doing so may cause fire, equipment failures, or malfunctions.
 The unit case is made of resin. If dropped or subjected to strong impact, the unit
may be damaged.
 When this unit is installed or removed from the panel, make sure to externally cut
3)
off all phases of the power supply. Failure to do so may cause malfunction or
failure of this unit.
DISPOSAL
PRECAUTIONS
 Please contact a certified electronic waste disposal company for the
environmentally safe recycling and disposal of your device.
TRANSPORTATION AND
STORAGE PRECAUTIONS
 The product is a precision instrument. During transportation, avoid impacts larger
than those specified in the general specifications by using dedicated packaging
boxes and shock-absorbing palettes.
Failure to do so may cause failures in the product.
After transportation, verify operation of the product and check for damage of the
mounting part, etc.
Items other than the following are equivalent to those of the PLC main unit.
For general specifications, refer to the manual of the PLC main unit.
