 Wiring Precautions
CAUTION
 Check the wiring to be sure it has been performed correctly.
There is a risk of motor run-away, injury, or accidents.
 Always use a power supply of the specified voltage.
There is a risk of fire or accident.
 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.
 Install breakers and other safety measures to provide protection against shorts in external wir-
ing.
There is a risk of fire.
 Provide sufficient shielding when using the Machine Controller in the following locations.
• Locations that are subject to noise, such as from static electricity
• Locations that are subject to strong electromagnetic or magnetic fields
• Locations that are subject to radiation
• Locations that are near power lines
There is a risk of device damage.
 Configure the circuits to turn ON the power supply to the CPU Module before the 24-V I/O
power supply. Refer to the following manual for details on circuits.
MP3000 Series MP3300 CPU Module Instructions Manual (Manual No.: TOBP C880725 23)
If the power supply to the CPU Module is turned ON after the external power supply, e.g., the 24-V
I/O power supply, the outputs from the CPU Module may momentarily turn ON when the power
supply to the CPU Module 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 Machine Controller.
There is a risk of injury or device damage.
 If you use MECHATROLINK I/O Modules, use the establishment of MECHATROLINK communi-
cations as an interlock output condition.
There is a risk of device damage.
 Connect the Battery with the correct polarity.
There is a risk of battery damage or explosion.
 Select the I/O signal wires for external wiring to connect the Machine Controller 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 outside
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.
