 Do not install or store the SERVOPACK in any of the following locations.
• Locations that are subject to direct sunlight
• Locations that are subject to ambient temperatures that exceed SERVOPACK specifications
• Locations that are subject to relative humidities that exceed SERVOPACK 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 SERVOPACK specifications
• Locations near devices that generate strong magnetic fields
• Locations that are subject to radiation
If you store or install the SERVOPACK in any of the above locations, the SERVOPACK may fail or be
damaged.
 Use the SERVOPACK in an environment that is appropriate for the SERVOPACK specifications.
If you use the SERVOPACK in an environment that exceeds SERVOPACK specifications, the SER-
VOPACK may fail or be damaged.
 The 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.
 Always install a SERVOPACK in a control panel.
 Do not allow foreign objects to enter a SERVOPACK or a Servomotor with a Cooling Fan and do
not cover the inlet or outlet of the Servomotor's cooling fan.
There is a risk of failure.
 Never install the SERVOPACK in an atmosphere containing halogen (fluorine, chlorine, bromine,
or iodine).
There is a risk of failure or damage.
 Wiring Precautions
 Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.
 Wiring and inspections must be performed only by qualified engineers.
There is a risk of electric shock or SERVOPACK failure.
 Check all wiring and power supplies carefully.
Incorrect wiring or incorrect voltage application to the output circuits may cause short-circuit fail-
ures. If a short-circuit failure occurs as a result of any of these causes, the holding brake will not
work. This could damage the machine or cause an accident that may result in death or injury.
 Connect the AC or DC power supplies to the specified SERVOPACK terminals.
• Connect an AC power supply to the L1, L2, and L3 terminals and the L1C and L2C terminals on the
SERVOPACK.
• Connect a DC power supply to the B1/
SERVOPACK.
There is a risk of failure or fire.
 If you use a SERVOPACK with the Dynamic Brake Hardware Option, connect an External
Dynamic Brake Resistor that is suitable for the machine and equipment specifications to the
specified terminals.
There is a risk of unexpected operation, machine damage, burning, or injury when an emergency
stop is performed.
