RNING
Connect the ground terminals on the SERVOPACK and Servomotor to ground poles according
to local electrical codes (100
Ω
or less for a SERVOPACK with a 100-VAC or 200-VAC power
supply, and 10
Ω
or less for a SERVOPACK with a 400-VAC power supply).
There is a risk of electric shock or fire.
Do not attempt to disassemble, repair, or modify the product.
There is a risk of fire or failure.
The warranty is void for the product if you disassemble, repair, or modify it.

UTION
The SERVOPACK heat sinks, regenerative resistors, External Dynamic Brake Resistors, Servo-
motors, and other components can be very hot while power is ON or soon after the power is
turned OFF. Implement safety measures, such as installing covers, so that hands and parts
such as cables do not come into contact with hot components.
There is a risk of burn injury.
Do not damage, pull on, apply excessive force to, place heavy objects on, or pinch cables.
There is a risk of failure, damage, or electric shock.
Do not use the product in an environment that is subject to water, corrosive gases, or flamma-
ble gases, or near flammable materials.
There is a risk of electric shock or fire.
NOTICE
Do not attempt to use a SERVOPACK or Servomotor that is damaged or that has missing parts.
Install external emergency stop circuits that shut OFF the power supply and stops operation
immediately when an error occurs.
Select the brake power supply for a Servomotor with a Holding Brake according to the power
supply voltage and capacity required for the Servomotor model, as given in manuals and cata-
logs. Also confirm the input voltage to the holding brake.
Always install a surge absorber as a protective device between the brake power supply and Ser-
vomotor.
There is a risk of damage to the Servomotor.
The time required for a holding brake to operate depends on the types of protective devices.
The time required for a holding brake to operate will also change if holding brakes are con-
nected in parallel. Always check the time required for a holding brake to operate on the actual
machine before you operate a Servomotor.
Always use a Servomotor and SERVOPACK in one of the specified combinations.
Do not touch a SERVOPACK or Servomotor with wet hands.
There is a risk of product failure.
