[DESIGN PRECAUTIONS]
[INSTALLATION PRECAUTIONS]
CAUTION
Do not bundle the control wires and the communication cables with the main circuit and the power
wires, and do not install them close to each other. They should be installed at least 100 mm (3.94 in.)
away from each other. Failure to do so may generate noise that may cause malfunctions.
CAUTION
Use the programmable controller in the operating environment that meets the general specifications
described in the user's manual of the CPU Module to use. Using the programmable controller in any
other operating environments may cause electric shocks, fires or malfunctions, or may damage or
degrade the module.
While pressing the installation lever located at the bottom of module, insert the module fixing tab into
the fixing hole in the base unit until it stops. Then, set the module in position using the fixing hole as
a supporting point. Incorrect mounting may cause malfunctions, failure or a drop of the module.
Secure the module with screws in an environment of frequent vibrations.
Be sure to tighten the screws using the specified torque. If the screws are loose, it may cause a short
circuit, malfunctions or a drop of the module. Overtightening the screws may damage the screws
and/or module, resulting in a short circuit, malfunctions or a drop of the module.
Before mounting/dismounting the module, be sure to shut off all phases of the external power supply
used by the system. Failure to do so may cause product damage.
Do not directly touch the conductive area or electronic components of the module. Doing so may
cause malfunction or failure in the module.
