NX-series CPU Unit Hardware User’s Manual (W535)
When the NX-series Controller is being installed in a cabinet or control panel, be sure to provide proper
ambient conditions as well as access for operation and maintenance.
Temperature Control
The ambient temperature within the NX-series Controller must be within the operating range of 0 to
55°C. When necessary, take the following steps to maintain the proper temperature.
• Provide enough space for good air flow.
• Do not install the Controller directly above equipment that generates a large amount of heat such
as heaters, transformers, or high-capacity resistors.
• If the ambient temperature exceeds 55°C, install a cooling fan or air conditioner.
Accessibility for Operation and Maintenance
• To ensure safe access for operation and maintenance, separate the Controller as much as possi-
ble from high-voltage equipment and power machinery.
• It will be easy to operate the Controller if it is mounted at a height of 1.0 to 1.6 m above the floor.
Improving Noise Resistance
• Do not mount the Controller in a control panel containing high-voltage equipment.
• Install the Controller at least 200 mm away from power lines.
• Ground the mounting plate between the Controller and the mounting surface.
