• 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.
