3. Installation

For installation/uninstallation details, refer to the respective PLC User's manual
Hardware Edition.

3.1 Connection to the PLC

This section describes the connection method to the PLC (FX

Series PLC is

used for the following example).

For installation method to other PLCs, refer to the respective PLC User's manual
Hardware Edition.

Procedure

1) Turn off the power.

Disconnect all the cables connected to the PLC main unit and special adapter.

Dismount the main unit and special adapter mounted on DIN rail or mounted

directly using screws.

2) Install an expansion board to the main unit.

For installation of expansion board, refer to the following manual:



Series User's Manual - Hardware Edition

3) Remove the special adapter connector cover

on the expansion board (Right fig.A).
In case of connecting this product to another
special adapter, please replace the
'expansion board' in the above description
with a 'special adapter' and perform the
procedure as indicated.

4) Slide the special adapter slide lock (Right

fig.B) of the main unit.
In case of connecting this product to another
special adapter, please replace the 'main
unit' in the above description with a 'special
adapter' and perform the procedure as
indicated. (Please replace the following
procedures similarly.)

5) Connect the

special adapter
(Right fig.C) to
the main unit as
shown on the
right.

6) Slide back the

special adapter
slide lock (Right
fig.B) of the main
unit to fix the
special adapter
(Right fig.C).

Connection precautions

Connect all the high-speed I/O special adapters before connecting other
special adapters when they are used in combination.

Do not connect a high-speed I/O special adapter on the left side of a
communication or analog special adapter.

INSTALLATION
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.

INSTALLATION
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

S, SO

, or NO

), 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.



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 special adapter securely to their designated connectors.
Loose connections may cause malfunctions.

WIRING
PRECAUTIONS



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.



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:

- 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.
