￫
The following section describes the special conditions for using
ESR5-NE-51-24VAC-DC devices at altitudes greater than
2000 m above sea level.
Observe the relevant device-specific data (technical data,
derating, etc.) according to the product documentation for the
individual 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 nominal input voltage (U
