Note the plinth is provided in the same packaging as the frequency converter but is not attached to Unit Sizes 61-64 during shipment. The plinth is required to

allow airflow to the drive to provide proper cooling. The Unit Sizes6 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 degrees or greater.

4.1.6 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.

4.1.7 Field Mounting

For field mounting the IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units are recommended.
