 Installation Precautions
 Securely mount the Servomotor to the machine.
If the Servomotor is not mounted securely, it may come off the machine during operation.
 Install the Servomotor or SERVOPACK in a way that will support the mass given in technical
documents.
 Install SERVOPACKs, Servomotors, regenerative resistors, and External Dynamic Brake Resis-
tors on nonflammable materials.
Installation directly onto or near flammable materials may result in fire.
 Do not step on or place a heavy object on the product.
There is a risk of failure, damage, or injury.
 Do not allow any foreign matter to enter the SERVOPACK or Servomotor.
There is a risk of failure or fire.
 Implement safety measures, such as installing a cover so that the rotating part of the Servomo-
tor cannot be touched accidentally during operation.
 Do not install or store the product in any of the following locations.
• Locations that are subject to direct sunlight
• Locations that are subject to ambient temperatures that exceed product specifications
• Locations that are subject to relative humidities that exceed product specifications
• Locations that are subject to condensation as the result of extreme changes in temperature
• Locations that are subject to corrosive or flammable gases
• Locations that are near flammable materials
• Locations that are subject to dust, salts, or iron powder
• Locations that are subject to water, oil, or chemicals
• Locations that are subject to vibration or shock that exceeds product specifications
• Locations that are subject to radiation
If you store or install the product in any of the above locations, the product may fail or be damaged.
 Use the product in an environment that is appropriate for the product specifications.
If you use the product in an environment that exceeds product specifications, the product may fail
or be damaged.
 A SERVOPACK or Servomotor is a precision device. Do not drop it or subject it to strong shock.
There is a risk of failure or damage.
 A Servomotor is a precision device. Do not subject the output shaft or the main body of the Ser-
vomotor to strong shock.
 Design the machine so that the thrust and radial loads on the motor shaft during operation do
not exceed the allowable values given in the catalog.
 The shaft opening of a Servomotor is not waterproof or oilproof. Implement measures in the
machine to prevent water or cutting oil from entering the Servomotor.
There is a risk of failure.
 In an application where the Servomotor would be subjected to large quantities of water or oil,
implement measures to protect the Servomotor from large quantities of liquid, such as installing
covers to protect against water and oil.
 In an environment with high humidity or oil mist, face Servomotor lead wires and connectors
downward and provide cable traps.
There is a risk of failure or fire due to insulation failure or accidents from short circuits.
 Wiring Precautions
 Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.
