Throughout this manual, the following notes are used to alert you to safety considerations:
Important: Identifies information that is critical for successful application and understanding of the product.
!
ATTENTION: Identifies information about practices or circumstances that can lead to personal
injury or death, property damage, or economic loss.
!
ATTENTION: Only qualified personnel familiar with the construction and operation of this
equipment and the hazards involved should install, adjust, operate, or service this equipment.
Read and understand this manual and other applicable manuals in their entirety before
proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: DC bus capacitors retain hazardous voltages after input power has been
disconnected. After disconnecting input power, wait ten (10) minutes for the DC bus capacitors
to discharge, then look at the built-in DC bus voltage meter. When the voltage is down to zero (0)
volts, open the cabinet doors and check the voltage across the DC bus bars, 1247 A,B,C (+ bus)
and 1145 A,B,C (- bus), with an external voltmeter to ensure the DC bus capacitors are discharged
before touching any internal components. Failure to observe this precaution could result in severe
bodily injury or loss of life.
ATTENTION: The user must provide an external, hardwired emergency stop circuit outside of the
drive circuitry. This circuit must disable the system in case of improper operation. Uncontrolled
machine operation may result if this procedure is not followed. Failure to observe this precaution
could result in bodily injury.
ATTENTION: The user is responsible for conforming with all applicable local, national, and
international codes. Failure to observe this precaution could result in damage to, or destruction
of, the equipment.
