• 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.
Consider PC operation, maintenance, and surrounding conditions when instal-
ling the CPM2A in a panel or cabinet.
The operating temperature range for the CPM2A 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 CPM2A 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.
Power lines and high-voltage equipment can cause electrical noise in the PC.
• Do not install the CPM2A in a panel or cabinet with high-voltage equipment.
• Allow at least 200 mm between the CPM2A and nearby power lines.
