• Never use the product in an environment subject to water, corrosive gases,
flammable gases, or combustibles.
Failure to observe this caution may result in electric shock or fire.
• Do not step on or place a heavy object on the product.
Failure to observe this caution may result in injury or malfunction.
• Do not cover the inlet or outlet ports and prevent any foreign objects from
entering the product.
Failure to observe this caution may cause internal elements to deteriorate resulting
in malfunction or fire.
• Be sure to install the product in the correct direction.
Failure to observe this caution may result in malfunction.
• Provide the specified clearances between the SERVOPACK and the con-
trol panel or with other devices.
Failure to observe this caution may result in fire or malfunction.
• Do not apply any strong impact.
Failure to observe this caution may result in malfunction.
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or malfunction.
• Do not connect a commercial power supply to the U, V, or W terminals for
the servomotor connection.
Failure to observe this caution may result in injury or fire.
• Securely connect the main circuit terminals.
Failure to observe this caution may result in fire.
• Do not bundle or run the servomotor main circuit cables together with the
I/O signal cables or the encoder cables in the same duct. Keep the servo-
motor main circuit cables separated from the I/O signal cables and encoder
cables by at least 30 cm.
Placing these cables too close to each other may result in malfunction.
• Use shielded twisted-pair cables or screened unshielded twisted-pair
cables for I/O signal cables and the encoder cables.
• The maximum wiring length is 3 m for I/O signal cables, 50 m for servomo-
tor main circuit cables and encoder cables, and 10 m for power supply
cables.
• Install the battery in the battery unit of the encoder cable with a battery unit.
• Voltage remains in the SERVOPACK even after the power supply is turned
OFF. To prevent electric shock, do not touch the input terminals for the
main circuit power supply or those for the control power supply.
Before wiring or inspections, confirm that the SERVOPACK has completely dis-
charged.
