DANGER
HAZARD DUE TO 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.
• Many components of the product, including the printed circuit
board, operate with mains voltage. Do not touch. Use only electri-
cally insulated tools.
• Do not touch unshielded components or terminals with voltage
present.
• The motor itself generates voltage when the motor shaft is rota-
ted. Block the motor shaft to prevent rotation prior to performing
any type of work on the drive system.
• AC voltage can couple voltage to unused conductors in the motor
cable. Insulate both ends of unused conductors of 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 15 minutes to allow the DC bus capacitors to discharge.
Measure the voltage on the DC bus as per chapter "DC bus
voltage measurement" and verify the voltage is <42 Vdc. The
DC bus LED is not an indicator of the absence of DC bus volt-
age.
• Install and close all covers before applying voltage.
Failure to follow these instructions will result in death or seri-
ous injury.
