Control Panel Dust-proof Design

The host controller and other printed circuit boards mounted in the control panel may malfunction due to the
effects of airborne particles (dust, cuttings, oil mist, etc.). Observe the following precautions to prevent air-
borne particles from entering the control panel.
• Always use a sealed structure for the control panel.
• Block cable openings with packing. (Refer to the figure labeled Cable Openings given below.)
• Install packing on the door and external cover to seal them. (Refer to the figure labeled Door Packing given
below.)
• Block all gaps.
• Oil may collect on the top surface and may enter the control panel through screw holes. Take special coun-
termeasures, such as using oil-proof packing.
