1.5 Safety Precautions
NOTICE
In places with poor power supply conditions, ensure that the input power is supplied within
the specified voltage range.
There is a risk of device damage.
Provide sufficient shielding when using the product in the following locations.
• Locations that are subject to noise, such as from static electricity
• Locations that are subject to strong electric or magnetic fields
• Locations that are subject to radioactivity
• Locations that are near power lines
There is a risk of device damage.
Select the I/O signal wires for external wiring to connect the product to external devices
based on the following criteria:
• Mechanical strength
• Noise interference
• Wiring distance
• Signal voltage
Separate the I/O signal cables for control circuits from the power cables both inside and out-
side the control panel to reduce the influence of noise from the power cables.
If the I/O signal lines and power lines are not separated properly, malfunction may occur.
CAUTION
Do not change any wiring while power is being supplied.
There is a risk of electrical shock or injury.
Always use a power supply of the specified voltage.
There is a risk of fire or malfunction.
Install breakers and other safety measures to provide protection against shorts in external
wiring.
There is a risk of fire.
Configure the circuits to turn ON the 24-V I/O power supply after one second or longer has
elapsed from when the power to the iC9200 was turned ON.
If the power to the iC9200 is turned ON after the external power supply, e.g., the 24-V I/O power supply, the
outputs from the iC9200 may momentarily turn ON when the power to the iC9200 turns ON. This can result
in unexpected operation that may cause injury or device damage.
Provide emergency stop circuits, interlock circuits, limit circuits, and any other required
safety measures in control circuits outside of the product.
There is a risk of injury or device damage.
Connect the battery with the correct polarity.
There is a risk of battery damage or explosion.
