2. 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.
•
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
, H
S, SO
, or NO
), 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.
•
Do not touch the conductive parts of the product directly.
Doing so may cause device failures or malfunctions.
•
Install the product securely using a DIN rail or mounting screws.
•
Install the product on a flat surface.
If the mounting surface is rough, undue force will be applied to the PC board, thereby causing nonconformities.
•
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.
3. 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.
•
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.
•
Perform class D grounding (grounding resistance: 100
as thick as possible.
Do not use common grounding with heavy electrical systems (refer to Subsection 5.1.2).
•
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.
•
For the CC-Link system, use CC-Link dedicated cables.
The performance of the CC-Link system cannot be guaranteed with any cable other than CC-Link dedicated cables.
For the maximum total extension length and the cable length between stations, observe the specification described
in the CC-Link master module manual.
With wiring outside the specification range, normal data transfer cannot be guaranteed.
•
Do not bundle the CC-Link exclusive cable together with or lay it close to the main circuit, high-voltage line, or load
line. As a guideline, lay the control line at least 100mm (3.94") or more away from the main circuit, high-voltage line,
or load line.
Otherwise, noise disturbance and/or surge induction are likely to take place.
•
Make sure to fix communication cables and power cables connected to the module by placing them in the duct or
clamping them.
Cables not placed in duct or not clamped may hang or shift, allowing them to be accidentally pulled, which may
result in malfunction or damage to the module and the cables.
