Caution Be sure to install the CPM2B correctly, as outlined in this manual. Failure to do so
may result in Board malfunction.
3-2-1 Installation Site Conditions
Note Do not install the CPM2B under any of the following conditions.
• Locations subject to direct sunlight.
• Locations subject to an ambient temperature below 0°C or over 55°C.
• Locations subject to an ambient humidity below 10% or over 90%.
• Locations subject to condensation as the result of severe changes in tempera-
ture.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to shock or vibration.
• Locations subject to exposure to water, oil, or chemicals.
Be sure that the conditions at the installation site conform to the CPM2B’s gen-
eral specifications. Refer to 2-1-1 General Specifications for details.
Note Provide proper shielding when installing in the following locations:
• Locations subject to static electricity or other sources of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radiation.
• Locations near to power supply lines.
3-2-2 Panel/Cabinet Installation
Consider PC operation, maintenance, and surrounding conditions when instal-
ling the CPM2B in a panel or cabinet.
The ambient operating temperature range for the CPM2B is 0_C to 55_C. Be
sure that there is adequate ventilation for cooling.
• Allow enough space for air circulation.
• Do not install the CPM2B above equipment that generates a large amount of
heat, such as heaters, transformers, or large resistors.
• Install a cooling fan or system when the ambient temperature exceeds 55_C.
