3.2 CAN-Bus Wiring
WIRING PRECAUTIONS
3.2.1
 Perform class D grounding (grounding resistance: 100 or less) to the shield
of the twisted shield cable (refer to subsection 3.2.3).
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.
 Install module so that excessive force will not be applied to communication
connectors or communication cables.
Failure to do so may result in wire damage/breakage or PLC failure.
 Make sure to affix the CAN bus connector with fixing screws.
Tightening torque should follow the specifications in the manual.
Loose connections may cause malfunctions.
 Make sure to properly wire to the terminal block (CAN bus connector) 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.
- Twist the end of strand wire and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires
of unspecified size.
- Affix the electric wires so that neither the terminal block nor the connected
parts are directly stressed.
 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 (refer to
the manual of the PLC main unit).
 Place the communication cable in grounded metallic ducts or conduits both
inside and outside of the control panel whenever possible.

 When executing control (data changes) to an operating PLC, construct an
interlock circuit in the sequence program so that the entire system operates safely.
In addition, when executing control such as program changes and operation
status changes (status control) to an operating PLC, thoroughly read the manual
and sufficiently confirm safety in advance. Especially in control from external
equipment to a PLC in a remote place, problems in the PLC may not be able to be
handled promptly due to abnormality in data transfer. Construct an interlock circuit
in the sequence program. At the same time, determine the actions in the system
between the external equipment and the PLC for protection against abnormalities
in data transfer.
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

2) Ground the shield wire or shield of a shielded cable.
Do not use common grounding with heavy electrical systems (refer to the
manual of the PLC main unit).
STARTUP AND
MAINTENANCE
PRECAUTIONS
 Do not disassemble or modify the PLC.
Doing so may cause fire, equipment failures, or malfunctions.
For repair, contact your local Mitsubishi Electric representative.
 Turn off the power to the PLC before connecting or disconnecting any extension
cable.
Failure to do so may cause equipment failures or malfunctions.
 Do not drop the product or exert strong impact to it.
Doing so may cause damage.
DISPOSAL PRECAUTIONS
*1 An FX2NC-CNV-IF or FX3UC-1PS-5V is necessary to connect the FX3U-CAN to
an FX3GC/FX3UC Series PLC.
 Please contact a certified electronic waste disposal company for the
environmentally safe recycling and disposal of your device.

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.
 For the operating status of each node in the case of a communication error, see
the FX3U-CAN user’s manual and the product manual of each node.
Erroneous output or malfunctions may cause an accident.
