 Make sure that all the terminal covers are mounted after wiring. Failure to mount them may cause electric shock.
(Assurez-vous que tout les couvercle sont attachés. Manque d'attachement peut causer mauvais fonctionnement
du dispositif, feu, ou commotion électrique.)

Avoid installing in a panel where high pressure equipment is installed.
Please install a surge suppressor in the device which is prone to noise.
 CC-Link communication signal line and other signal lines, auxiliary power supply line, the power supply frequency
input line to prevent the introduction of noise, please do not approach and unity of the power line or high voltage
line. Please separate the separation distance when the signal line and the power line / high voltage line are parallel
as a guide. (Excluding terminal block input section)
[CC-Link communication signal line]
Condition
All power lines
[Other signal line / auxiliary power line / power frequency input line]
Condition
Power line of 600V or less
Other power lines
Please connect the shield wire of the CC-Link communication cable to the SLD terminal of each of the CC-Link
communication terminals.
And "SLD" of each terminal "FG" are connected inside the unit.
 To prevent induction noise, keep control lines and communication cables as far away from power lines as possible.
(We recommend that you keep a distance of 100 mm or longer between them.)
Do not place them in a control panel containing high-voltage equipment.
Mount surge absorbers on equipment that is likely to produce noise.
 Connect both ends of the shielded wire in a CC-Link communication cable to the "SLD" terminal of the units.
"SLD" and "FG" are connected to each other inside each unit.
Make sure to insulate the shielded wire using vinyl tape or the like.
 For the actual usage, perform class D grounding dedicated for the "FG" terminal.
 Perform insulation withstand voltage tests and insulation resistance tests without connecting the FG terminal to the
external case (ground).
 Precautions concerning the preparation before use
 Make sure that your installation site meets the requirements for the operation environment and usage conditions.
 Before use, configure the settings of the product. Wrong settings may cause the product to malfunction.
 Check the power ratings of the product.
 After installing the product and performing wiring work, peel off the dustproof seal.
Failure to peel it off may cause the product to malfunction due to internal heat generation.
 The product has a built-in lithium battery. It is not connected to the product when shipped from the factory. Connect it
before using the product.
(See "6. Battery Installation and Replacement".)
 Precautions for use
 Use the product within the ratings specified of this manual. If it is used outside the ratings, it may cause not only
malfunction or failure but also fire or burn damage.
