NOTICE
One or more door fans are required on the enclosure to
remove heat not contained in the back channel of the
drive. The fans also remove any additional losses
generated by other components inside the drive.
Ensure that the fans supply adequate airflow over the heat
sink. To select the appropriate number of fans, calculate
the total required airflow. The flow rate is shown in
Table 4.2 .

4.6 Lifting the Drive
Always lift the drive using the dedicated eye bolts at the
top of the drive. See
Illustration 4.3 .
WARNING
HEAVY LOAD
Unbalanced loads can fall or tip over. Failure to take
proper lifting precautions increases risk of death, serious
injury, or equipment damage.
•
Move the unit using a hoist, crane, forklift, or
other lifting device with the appropriate weight
rating. See
chapter 3.2 Power Ratings, Weight,
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
transport. For measurements and center of
gravity, see
chapter 10.9 Enclosure 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 Illustration 4.3 . 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.
