16 Attachment - using devices at altitudes greater than 2000 m above sea level
Using the device at altitudes greater than 2000 m above sea level up to
max. 4500 m above sea level is possible under the following conditions:
▶ 1. Limit the nominal input voltage (U
N
) in accordance with the table below.
Observe the technical data for the device.
▶ 2. Limit the maximum switching voltage in accordance with the table
below. Observe the technical data for the device.
▶ 3. Reduce the maximum ambient temperature for operation by the
corresponding factor in accordance with the table below.
▶ 4. If derating is specified, offset all the points of the derating curve by the
corresponding factor in accordance with the table below.
