However, if noise affects the Unit, ground the end of the shield on the Input Unit side.
You can use the NX-TBX01 Shield Connection Unit to ground more than one shield.
Precautions for Correct Use
• When you do not use some inputs, connect VI and II input terminals with COM terminal.
• Separate the lines from power lines (e.g., AC power supply lines or power lines).
