Ensure that the fans supply adequate airflow over the heat sink. To select the appropriate number of fans, calculate the total re-
quired airflow. The flow rate is shown in the following table.

5.3.3 Lifting the Drive
W A R N I N G
HEAVY LOAD
Unbalanced loads can fall or tip over. Failure to take proper lifting precautions increases risk of death, serious injury, or equip-
ment damage.
Move the unit using a hoist, crane, forklift, or other lifting device with the appropriate weight rating. See 5.1 Power Ratings,
Weights, and Dimensions for the weight of the drive.
Failure to locate the center of gravity and correctly position the load can cause unexpected shifting during lifting and trans-
port. For measurements and center of gravity, see 5.1 Power Ratings, Weights, and Dimensions.
The angle from the top of the drive module to the lifting cables affects the maximum load force on the cable. This angle
must be 65° or greater. Refer to the following illustration. Attach and dimension the lifting cables properly.
Never walk under suspended loads.
To guard against injury, wear personal protective equipment such as gloves, safety glasses, and safety shoes.
Always lift the drive using the dedicated eye bolts at the top of the drive. See the following illustration.
