Precautions for Use

About installation
• Do not drop the device and modules, hit them, or give a strong shock on them.
Otherwise, failure may be caused.
• Use your cellular phone or PHS at least 1m away from the product main unit in operation, transmission
cables, and I/O cable. Otherwise, the system may malfunction.
• When connecting a connector or cable and mounting a module to the base unit, firmly fix it with screws.
Insufficient screwing can cause failure or malfunction due to vibrations.

About power supply wiring
• Separate the cables as far as possible from other cables. In particular, separate them at least 200mm
from power lines.
• The size of the terminal screw is M3.5. Use an appropriate crimp-style terminal with a width of 5.5mm or
less for the M3.5 screw.
• To avoid breaking the screw, use a screwdriver that matches the screw.
• Do not connect anything to the NC terminals and terminal or pins that are not described.

About use of sample programs
• For the sample programs provided in the Operating Instructions, the customer shall make operation
check before using them.
To prevent accident from malfunctioning, confirm adequately before operating.

About maintenance
• Be careful of static electricity when handling the module removed from the base unit.
Place the module removed from the unit on a conductive mat or conductive bag (a bag containing a
spare board, etc.) on a grounded table.
Otherwise, parts can be damaged due to static electricity.
• Before touching the device or modules, touch a grounded metal part to discharge the static electricity on
your body. Otherwise, static electricity on your body can cause malfunction or failure.
• When holding the module, hold the handle or ejector on the front panel, and do not hold the printed
circuit board part directly. The static electricity charged on your hand may damage the parts, the electric
charge on the circuit may cause an electric shock, or the circuit part may injure your hand.
• Wipe the dirt on the device or modules with a soft cloth.
For severe stains, use a cloth soaked with water and wrung out.
Leaving them stained may cause misjudgment or malfunction.
• Do not use benzene or thinner to remove stains on the device and modules.
It may cause deformation or discoloration of the device panel and modules.
• To keep the system normal and prevent unnecessary troubles, perform the daily inspection, periodic
inspection, and cleanup.
