Mounting Units
This section describes how to mount Units to the CK3M-series Controller.
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 Controller 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 during installation in the following locations.

Installation in a Control Panel
Installation in Cabinets or Control Panels
When the CK3M-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 CK3M-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 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.
