5 Installation
• Power cables and signal cables adversely affect each other. Do not wire them in parallel.
• Noise induction may occur if the Box PC is installed in a panel that includes high-voltage devi-
ces. Wire and install them as far apart as possible.
• Either install the Box PC a minimum of 200 mm away from high-voltage lines or power lines, or
place the high-voltage lines or power lines in metal tubing and completely ground the metal tub-
ing to 100 Ω or less.

 Wiring Ducts
Whenever possible, route the cables and wires through wiring ducts.
Install the wiring ducts so that it is easy to route the wires from the Industrial Box PC directly into
the duct.
Additional Information
Refer to Distance for Cooling on page 5 - 16 for the minimum required distances.
It is convenient to use wiring ducts that have the same depth as the Industrial Box PC.
