4.1 Installation notes
-
Check to see if the device is installed in a manner appropriate to the application, and that it is operated within the
admissible plant parameters.
-
The device is intended to be installed in control cabinets, machines, or plants.
-
Disconnect the device from the mains voltage on all poles prior to starting service or repair work.
-
All incoming and outgoing lines without a connection to the power supply network must be laid with shielded and
twisted lines. The shield must be grounded on the device side.
-
Do not lay the input and output cables close to components or lines through which current is flowing.
-
Do not connect any additional loads to the screw terminals for the voltage supply of the device.
-
Both the choice of cable material for the installation as well as the electrical connection of the device must conform
to the local requirements of VDE 0100 "Regulations on the Installation of Power Circuits with Nominal Voltages
below 1000 V" or the appropriate regulations for the country.
-
The electromagnetic compatibility conforms to the standards and regulations cited in the technical data.

Chapter 6 "Technical data"
-
In line with the operating conditions, the temperature may exceed 60 °C at the terminals.
As a result, the insulation of the cables connected at the terminals may be damaged.
The affected cables must be heat-resistant up to at least 80 °C.
Caution
As the measurement input and the USB interface are not galvanically isolated, a short circuit between a grounded
sensor and the ground of a PC which is also grounded (e.g., with desktop computers) must be avoided.
Please check the isolation on the sensor side, or use a laptop in battery mode for setup applications.
