Mounting frame sizes A4, A5, B1, B2, B3, B4, C1, C2, C3 and C4 on a non-solid back wall, the frequency converter
must be provided with a
backplate A due to insufficient cooling air over the heat sink.
With heavier drives (B4, C3, C4) use a lift. First wall-mount the 2 lower bolts - then lift the drive onto the lower
bolts - finally fasten the drive against the wall with the 2 top bolts.
Safety Requirements of Mechanical Installation
WARNING
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.
NOTE
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.
Field Mounting
For field mounting the IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units are recommended.
