Turn off and lock out all power supplying this device before working on it. Installation and
maintenance work on this device must by carried out by authorized persons with the
appropriate electrical training only.
Damage to, or destruction of, the Data Manager. Material damage.
Observe the prescribed minimum clearances between the network cable and the
installation components that carry mains voltage, or use suitable insulation.
Always lay the data and power lines separately or in separate pipelines. Observe EN
50174-2 here.
NOTICE
Overvoltage. Material damage.
If network cables are laid in the outdoor area, overvoltages can arise as a result of lightning
strikes, for example.
The network cable must be safeguarded with suitable overvoltage protection.
NOTICE
Damage to the sensor bar through transient overvoltages. Material damage.
Install additional overvoltage arresters in accordance with SPD Type 1 (primary protection)
und SPD Type 2 (medium protection) upstream of the Data Manager.
Ensure that the Data Manager that supplies the sensor bar with voltage can be
disconnected, for example, with a miniature circuit breaker. This must be labeled as a
circuit breaker for the Data Manager, and it must be easily accessible.
