Planning the cabinet
5.1 Ambient
conditions
The nominal data (see chapter 4) are valid for
•
ambient temperatures
from +5° to +45° C and
•
installation elevation
from 0 to 1000 m above sea level.
Note:
In case you want to use the drive controller under other
ambient conditions than the indicated ones (up to a maximum
of +55 °C ambient temperature and/or a maximum installation
elevation of 5000 m above sea level), you have to consider the
load capacity. The power data are reduced by the load
capacity.
CAUTION
Damage caused by use under non-specified
ambient conditions!
⇒
Drive controllers which are being operated under
other ambient conditions than the specified ones
might be damaged. Any claim under guarantee will
expire.
CAUTION
Damage caused by overloading of the drive
controller!
⇒
In case you want to use the drive controllers for
others than the indicated ambient conditions, make
sure the load capacity is sufficient. For the purpose
of verification please see the load capacity on the
diagrams in Fig. 5-1 and follow the subsequent
instructions!
