2. Installation
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.
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,
2 2 2 2
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.
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.
 Make sure to attach the top cover, offered as an accessory, before turning on
the power or initiating operation after installation or wiring work.
Failure to do so may cause electric shock.
 Connect the extension cables securely to their designated connectors.
Loose connections may cause malfunctions.
2.1 Connection with PLC
The FX -1PG-E connects on the right side of an PLC main unit or extension
2N
units/blocks (including special function units/blocks).
For connection to an FX Series, FX Series PLC or FX
3UC 2NC 2NC
extension block, an FX -CNV-IF or FX -1PS-5V is required.

3. Specifications
DESIGN
PRECAUTIONS
 Make sure to have 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 CPU 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 CPU 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 a case.
3) Note that when an error occurs in a relay, triac or transister output device,
the output could be held either on or off.
For output signals that may lead to serious accidents, external circuits
and mechanisms should be designed to ensure safe machinery operation
in such a case.
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 likely to take place.
As a guideline, lay the control line at least 100 mm (3.94") or more away from
the main circuit or high-voltage lines.
2) Ground the shield wire or shield of a shielded cable. Do not use common
grounding with heavy electrical systems.
 Install module so that excessive force will not be applied to the terminal blocks.
Failure to do so may result in wire damage/breakage or PLC failure.
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
 Connect the DC power supply wiring to the dedicated terminals described in this
manual.
If an AC power supply is connected to a DC input/output terminal or DC power
supply terminal, the PLC will burn out.
 Make sure to attach the top cover, offered as an accessory, before turning on the
power or initiating operation after installation or wiring work.
Failure to do so may cause electric shock.
 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 properly wire the extension equipment 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
Series PLC the manual.
- Tightening torque should follow the specifications in the manual.
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 PLC is a precision instrument. During transportation, avoid impacts larger
than those specified in the general specifications of the PLC main unit manual.
Failure to do so may cause failures in the PLC.
After transportation, verify the operations of the PLC.
