WARNING
Fire Hazard
Do not put flammable or combustible materials on top of the drive and do not install the drive
near flammable or combustible materials. Attach the drive to metal or other noncombustible
material.
Flammable and combustible materials can start a fire and cause serious injury or death.
Crush Hazard
Wear eye protection when you do work on the drive.
If you do not use correct safety equipment, it can cause serious injury or death.
Use a crane or hoist to move large drives when necessary.
If you try to move a large drive without a crane or hoist, it can cause serious injury or death.
NOTICE
Damage to Equipment
When you touch the drive and circuit boards, make sure that you observe correct electrostatic
discharge (ESD) procedures.
If you do not follow procedures, it can cause ESD damage to the drive circuitry.
Do not break the electrical connection between the drive and the motor when the drive is
outputting voltage.
Incorrect equipment sequencing can cause damage to the drive.
Make sure that all connections are correct after you install the drive and connect peripheral
devices.
Incorrect connections can cause damage to the drive.
Note:
Do not use unshielded wire for control wiring. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the drive.
Unshielded wire can cause electrical interference and unsatisfactory system performance.
