24 D50 PLC User's Manual
• Locations subject to direct impact greater than 10 G or vibrations greater than 1 G @
57-2000 Hz.
• Direct sunlight.
• Presence of water, oil, and other chemicals.
Electrical Noise Considerations
• Do not install near high-tension wires, high-voltage devices, power cables, power devices,
and other devices which generate large power surges or electromagnetic fields when starting
and stopping.
• Do not place near wireless communications devices with transceivers, such as walkie talkies,
cellular phones, or shortwave radios.
Control Panel Installation
• Leave enough space at the top of unit from other devices or wiring ducts to allow ventilation
space and easy replacement and wiring of the unit (see the following diagrams).
• Do not mount the PLC system rotated vertically, or facing up or down. This will prevent
proper air cooling of the PLC CPU, which will cause abnormal overheating inside the PLC
(see the following diagrams).
• Avoid installation over heat generating equipment such as heaters, transformers, and power
resistors.
• Avoid radiation noise by leaving a minimum distance of 4 inches (100 mm) from the surface
of each unit to the power cable, and the noise-generating device (motor starter, solenoid, etc.).
