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 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 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 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.
•
Do not apply the 24 V DC power before wiring the entire AnyWireASLINK system.

•
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 the shielded cable at one point on the PLC. However, do not use common grounding with
heavy electrical systems.
•
Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables or malfunction due to poor
contact.
•
When disconnecting the cable from the module, do not pull the cable by the cable part.
For the cable connected to the terminal block, loosen the terminal screw.
Pulling the cable connected to the module may result in malfunction or damage to the module or cable.
For the wiring of the AnyWireASLINK system, refer to the "AnyWireASLINK Series Technical Manual"
(prepared by AnyWire).
