[INSTALLATION PRECAUTIONS]
!
CAUTION
• Use the CC-Link board in an environment as described in the general specifications listed in this
operating manual.
If the board is used in an environment outside the ranges described in the general
specifications, it may result in an electric shock, fire, malfunctioning, damage to or deterioration
of the product.
• Do not directly touch the conductive area of the CC-Link board.
This will result in malfunctioning or failure of the CC-Link board.
• Fix the CC-Link board securely with the installation screws and tighten the installation screws
within the specified torque range.
If the screws are loose, this will lead to an error in operation.
If the screws are tightened too much, this will damage the screws and cause a short.
• Always make sure to touch the grounded metal to discharge the electricity charged in the body,
etc., before touching the CC-Link board.
Failure to do so may cause a failure or malfunctions of the CC-Link board.
[WIRING PRECAUTIONS]
!
DANGER
• Always turn off all external power before performing installation, wiring or other work.
If all power is not turned off, there is a risk of electric shock, damage to the product, or
malfunctioning.
• When turning on the power and operating the module after installation and wiring are completed,
always attach the terminal cover that comes with the product.
There is a risk of electric shock if the terminal cover is not attached.
!
CAUTION
• Always ground the FG terminal on the PC side using D type grounding (Class 3 grounding) or
higher specifically for the PC. Otherwise, there is a risk of malfunctioning.
If a malfunctioning occurs even when the PC unit is grounded, ground both the FG terminal for
the PC unit and the SLD terminal for the CC-Link board.
• Tighten the terminal screws within the specified torque range.
If the terminal screws are loose, this will lead to a short or malfunctioning.
If the terminal screws are tightened too much, this will damage the screws and CC-Link board,
causing a short or malfunctioning.
• Take care that foreign objects such as chips or wiring debris do not get inside the CC-Link
board.
This can result in fire, failure or malfunctioning.
