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 CPM1A in a panel or cabinet.
Overheating The operating temperature range for the CPM1A 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 CPM1A 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.

Electrical Noise Power lines and high-voltage equipment can cause electrical noise in the PC.
• Do not install the CPM1A in a panel or cabinet with high-voltage equipment.
• Allow at least 200 mm between the CPM1A and nearby power lines.

Accessibility Ensure that the CPM1A can be accessed for normal operation and mainte-
nance.
• Provide a clear path to the CPM1A for operation and maintenance. High-volt-
age equipment or power lines could be dangerous if they are in the way during
routine operations.
• The PC will be easiest to access if the panel or cabinet is installed about 3 to 5
feet off of the floor.
