5.1.2. Mechanical mounting
1.
Drill holes in accordance with the measurements given.
2.
You must provide screws suitable for the surface on which you want to mount the fre-
quency converter. Retighten all four screws.
The frequency converter allows side-by-side installation. Because of the need for coolingallow for
a minimum of 100 mm free air passage above and below the frequency converter.
The back wall must always be solid.
5.1.3. 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 damage or injury, 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 aver-
age 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.
5.1.4. Field Mounting
For field mounting the IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units (planned) are recommended.
