PRECAUTIONS
•Make sure to have the following safety circuits outside of the PLC to ensure safe
system operation even during extension power supply unit 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).
1. Introduction
This manual supplements the contents of the FX3UC (D,DSS) Series Hardware Manual
(Manual Number: JY997D28601A). This manual covers basic hardware details for the
following FX2NC Series Extension Block. For details, refer to FX3UC SERIES USER'S
MANUAL - Hardware Edition (Manual number: JY997D28701).
2. Specifications
2.1 General Specifications
The general specifications are equivalent to the PLC main unit. For the general
specifications, refer to the FX

DESIGN
PRECAUTIONS
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 transistor 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.

For details, refer to the FX
3UC Series User's Manual - Hardware Edition.
4. Example Wiring
For details, refer to the FX 3UC Series User's Manual - Hardware Edition.
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, Cl2, H2S, SO2, or NO2), flammable gas,
vibration or impacts, or exposed 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.
•Make sure to cut off all phases of the power supply externally before attempt-
ing installation or wiring work.
Failure to do so may cause electric shock.
•Use screwdrivers carefully when performing installation work, thus avoiding
accident or product damage.
•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.
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 specified 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.
•Connect the AC power supply wiring to the dedicated terminals specified 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.
•Do not wire vacant terminals externally.
Doing so may damage the product.
•Perform class D grounding (grounding resistance: 100Ωor less) to the
grounding terminal on the main unit.
Do not use common grounding with heavy electrical systems (refer to the
manual of the PLC main unit).
•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.
