17.1 Using 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 rated control circuit supply voltage (U
S
) 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 corre-
sponding 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.
The following section describes the special conditions for using
PSR devices at altitudes greater than 2000 m above sea level.
Observe the relevant device-specific data (technical data, derat-
ing, etc.) according to the product documentation for the individ-
ual device.
