System Design and Installation
• Use ground lines with a minimum thickness of 3.5 mm
• If no-fuse breakers are installed at the top and the power supply line is wired from the lower duct, use
• No-fuse breakers, surge absorbers, and noise filters should be positioned near the input terminal
• Wire the noise filter as shown at the left in the following illustration. The noise filter should be installed
• Use twisted-pair cables for the power supply cables whenever possible, or bind the cables.
• Separate power supply cables and signal cables when wiring.
