17.1 Using at altitudes greater than 2000 m above sea level
36
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.
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
table below. Observe the technical data for the device.
U according to the technical data for the device U
S
< 150 V AC/DC
> 150 V AC/DC
▶2. Limit the maximum switching voltage in accordance with the table
below. Observe the technical data for the device.
Max. switching voltage according
to the technical data for the
device
< 150 V AC/DC
> 150 V AC/DC
▶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.
