3. Wiring
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
2
, H
2
S, SO
2
or NO
2
), 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.
•
Make sure to affix the expansion board with tapping screws.
Tightening torque should follow the specifications in the manual.
Loose connections may cause malfunctions.
•
Use screwdrivers carefully when performing installation work, thus avoiding
accident or product damage.
•
When drilling screw holes or wiring, make sure that cutting and wiring debris do
not enter the ventilation slits of the PLC.
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 expansion board securely to their designated connectors.
Loose connections may cause malfunctions.
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) If an overload of the 24 V DC service power supply occurs, the voltage
automatically drops, inputs in the PLC are disabled, and all outputs are turned
off.
External circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.
DESIGN
PRECAUTIONS
•
Do not bundle the control line together with or lay it close to the main circuit or
power line. As a guideline, lay the control line at least 100 mm (3.94") or more
away from the main circuit or power line.
Noise may cause 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 to the dedicated terminals specified in the manual
of the PLC main unit.
If an AC power supply is connected to a DC input/output terminal or DC power
supply terminal, the PLC will burn out.
3.1 Applicable Cable and Terminal Tightening Torque
3.1.1
Terminal block (European type)
1) Wire size
Wiring to input device should use 22 to 20 AWG wire.
2) Applicable cable
3) Termination of cable end
Strip the coating of strand wire and twist the cable core before connecting it,
or strip the coating of single wire before connecting it.
An alternative connection is to use a ferrule with insulating sleeve.
<Reference>
*1 Old model name: CRIMPFOX ZA 3
*2 Old model name: CRIMPFOX UD 6
When using a ferrule with insulation sleeve, choose a wire with proper cable
sheath referring to the above outside dimensions, or otherwise, the wire
cannot be inserted easily.
The tightening torque must be 0.22 to 0.25 N
•
m. Do not tighten terminal
screws exceeding the specified torque. Failure to do so may cause equipment
failures or malfunctions.
4) Tool
For tightening the terminal, use a
commercially available small
screwdriver having a straight form that is
not widened toward the end as shown
right.
Caution:
If the diameter of screwdriver grip is too
small, tightening torque will not be able
to be achieved. Use the following recommended screwdriver or an
appropriate replacement (grip diameter: approximately 25 mm (0.98")).
<Reference>
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
malfunctions under the influence of noise:
- Do not bundle the power line or input 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.
•
Make sure to properly wire to the terminal block (European type) 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.

3.3 Grounding
Grounding should be performed as stated below.
•
The grounding resistance should be 100
Ω
or less.
•
Independent grounding should be performed for best results.
When independent grounding is not performed, perform "shared grounding" of
the following figure.

•
The grounding wire size should be AWG 22 to 20 (0.3 to 0.5 mm
2
).
•
The grounding point should be close to the PLC, and all grounding wire should
be as short as possible.
3.4 Instructions for connecting input devices
The input current of this PLC is 5 mA/24 V DC. Use input devices applicable to
this minute current.
If no-voltage contacts (switches) for large current are used, contact failure may occur.
<Example> Products of OMRON
3.4.1
In the case of input device with built-in series diode
The voltage drop of the series diode should be approx. 4 V or less.
When lead switches with a series LED are used, up to two switches can be
connected in series. Also make sure that the input current is over the input-
sensing level while the switches are ON.
