Wiring
Selecting, Separating, and Laying External Cables
• Check the wiring to be sure it has been performed correctly.
There is a risk of motor run-away, injury, or an accident.
• Always use a power supply of the specified voltage.
There is a risk of burning.
• In places with poor power supply conditions, take all steps necessary to ensure that the input power
supply is within the specified voltage range.
There is a risk of device damage.
• Install breakers and other safety measure to provide protection against shorts in external wiring.
There is a risk of fire.
• Provide sufficient shielding when using the MP2000 Series Machine Controller in the following loca-
tions.
There is a risk of device damage.
Noise, such as from static electricity
Strong electromagnetic or magnetic fields
Radiation
Near to power lines
• When connecting the battery, connect the polarity correctly.
There is a risk of battery damage or explosion.
• Only qualified safety-trained personnel should replace the battery.
If the battery is replaced incorrectly, machine malfunction or damage, electric shock, or injury may result.
• When replacing the battery, do not touch the electrodes.
Static electricity may damage the electrodes.
• After replacing the battery, separate the used battery from regular waste and deal with it according to
the applicable local regulations.
• Consider the following points when selecting the I/O signal lines (external cables) to connect the
MP2000 Series Machine Controller to external devices.
Mechanical strength
Noise interference
Wiring distance
Signal voltage, etc.
• It is possible to reduce the influence of noise from the power lines. For that purpose, separate the I/O
signal lines from the power lines both inside and outside the control box.
If the I/O signal lines and power lines are not separated properly, malfunctioning may result.
