INSTALLATION
PRECAUTIONS
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 extension cables securely to their designated connectors.
Loose connections may cause malfunctions.
2.1 Connection with PLC
The FX

3U
blocks (including special function units/blocks).
For connection to an FX
Series PLC or FX
Series PLC extension block, an
3UC
2NC
FX
-CNV-IF or FX
-1PS-5V is required.

DESIGN
PRECAUTIONS
Make sure to have the following safety circuits outside of 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 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.
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 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. 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 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 terminal 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.
WIRING
PRECAUTIONS
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.
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
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.

3.7 Wiring Precautions
1) The power supply used for FP, RP, PG0, and CLR should be separate from
the power supply used for the other signals.
2) In an environment with a lot of noise, when malfunctions such as position
gap occur, the influence of noise may be mitigated with the following
measures.
Attach a noise filter (TDK-Lambda Corp. MXB-1210-33 or similar) on the
FX
-1PG power supply line, one on the end nearest the servo amplifier,
3U
and one on the end nearest the power supply unit.
Attach a ferrite core (TDK Corp. ZCAT3035-1330 or similar) to the VIN, FP,
RP, PG0, and CLR signal wires, on the end nearest the servo amplifier.
