This section describes the installation of the CK3M-series Unit.
Precautions for Safe Use
Always turn OFF the power supply to the Controller before attempting any of the following.
• Mounting or removing CK3W-AX Units or Motion Controllers
• Assembling the Units
• Setting rotary switches
• Connecting cables or wiring the system
• Connecting or disconnecting the terminal blocks or connectors.
The built-in power supply of the CPU Unit may continue to supply power after the power supply
is turned OFF. The POWER indicator remains lit as long as power is supplied. Make sure that
the POWER indicator is not lit before you perform any of the above operations.
Precautions for Correct Use
• Follow the instructions in this manual to correctly perform installation.
• Do not operate or store the Units in the following locations. Doing so may result in burning, in
operation stopping, or in malfunction.
a) Locations subject to direct sunlight
b) Locations subject to temperatures or humidity outside the range specified in the specifica-
tions
c) Locations subject to condensation as the result of severe changes in temperature
d) Locations subject to corrosive or flammable gases
e) Locations subject to dust (especially iron dust) or salts
f) Locations subject to exposure to water, oil, or chemicals
g) Locations subject to shock or vibration
• Take appropriate and sufficient countermeasures if the Units are installed in the following lo-

Installation in a Control Panel
Installation in Cabinets or Control Panels
Please consider operability, maintainability, and environmental resistance when installing the CK3M-
series Units in the cabinet or the control panel.
Consideration for Ambient Temperature
The operating ambient temperature of the CK3M-series must be within the range from 0 to 55°C.
When necessary, take the following measures to maintain the proper temperature.
• Provide enough space for good air flow.
• Do not install the Controller 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.
