Illustration 5.7: Recommended lifting method, frame size
F4.
NB!
Note the plinth is provided in the same packaging as the frequency converter but is not attached to frame sizes F1-F4 during shipment.
The plinth is required to allow airflow to the drive to provide proper cooling. The F frames should be positioned on top of the plinth in
the final installation location. The angle from the top of the drive to the lifting cable should be 60° C or greater.
5.1.6 Safety Requirements of Mechanical Installation
Pay attention to the requirements that apply to integration and field mounting kit. Observe the information in the list to avoid serious
injury or equipment damage, especially when installing large units.
The frequency converter is cooled by means of air circulation.
To protect the unit from overheating, it must be ensured that the ambient temperature
does not exceed the maximum temperature stated for the
frequency converter
and that the 24-hour average temperature
is not exceeded
. Locate the maximum temperature and 24-hour average in the paragraph
Derating for Ambient Temperature
.
If the ambient temperature is in the range of 45 °C - 55 ° C, derating of the frequency converter will become relevant, see
Derating for Ambient
Temperature
.
The service life of the frequency converter is reduced if derating for ambient temperature is not taken into account.
5.1.7 Field Mounting
For field mounting the IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units are recommended.
