@ DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
• Only appropriately trained persons who are familiar with and
understand the contents of this manual and all other pertinent
product documentation and who have received safety training to
recognize and avoid hazards involved are authorized to work on
and with this drive system. Installation, adjustment, repair and
maintenance must be performed by qualified personnel.
• The system integrator is responsible for compliance with all local
and national electrical code requirements as well as all other
applicable regulations with respect to grounding of all equipment.
• Supplement the motor cable grounding conductor with an addi-
tional protective ground conductor to the motor housing.
• Do not touch unshielded components or terminals with voltage
present. Use only electrically insulated tools.
• The motor generates voltage when the shaft is rotated. Prior to
performing any type of work on the drive system, block the motor
shaft to prevent rotation.
• AC voltage can couple voltage to unused conductors in the motor
cable. Insulate both ends of unused conductors in the motor
cable.
• Do not short across the DC bus terminals or the DC bus capaci-
tors.
• Before performing work on the drive system:
– Disconnect all power, including external control power that
may be present.
– Place a "Do Not Turn On" label on all power switches.
– Lock all power switches in the open position.
– Wait for the DC bus capacitors to discharge (see the product
manual for the power stage). Then measure the DC bus volt-
age and verify it is less than < 42 V
dc
(see the product manual
for the power stage).
• Install and close all covers before applying voltage.
Failure to follow these instructions will result in death or serious
injury.
