 Wiring
• 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 Unit/CPU Module before the 24-
V I/O power supply. Refer to the following manual for details on circuits.
MP3000 Series CPU Unit Instructions (Manual No.: TOBP C880725 16)
MP3000 Series MP3300 CPU Module Instructions Manual (Manual No.: TOBP C880725 23)
If the power supply to the CPU Unit/CPU Module is turned ON after the external power supply, e.g., the
24-V I/O power supply, the outputs from the CPU Unit/CPU Module may momentarily turn ON when
the power supply to the CPU Unit/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 commu-
nications 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.
• Suitable battery replacement must be performed and it must be performed only by an experi-
enced technician.
There is a risk of electrical shock, injury, or device damage.
• Do not touch the electrodes when replacing the Battery.
Static electricity may damage the electrodes.
• 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
