NOTE!
The plinth is provided in the same packaging as the
Adjustable frequency drive but is not attached to frame
sizes F1-F4 during shipment. The plinth is required to allow
airflow to the adjustable frequency 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.
In addition to the drawings above, a spreader bar is an
acceptable way to lift the F Frame.
5.1.6 Safety Requirements of Mechanical
Installation
WARNING
Pay attention to the requirements that apply to integration
and the field mounting kit. Observe the information in the
list to avoid serious injury or equipment damage,
especially when installing large units.
CAUTION
The Adjustable frequency drive 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 Adjustable frequency
drive and that the 24-hour average temperature is not
exceeded . Locate the maximum temperature and 24-hour
average in 8.6.2 Derating for Ambient Temperature .
If the ambient temperature is in the range of 133°–131°F
[45
°
–55
°
C], derating of the Adjustable frequency drive will
become relevant, see 8.6.2 Derating for Ambient
Temperature .
The service life of the Adjustable frequency drive is
reduced if derating for ambient temperature is not taken
into account.
5.1.7 Field Mounting
IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units are
recommended.
