6 Electrical connection
CAUTION! Electric current!
The electrical connection of the DM08 should only be carried out by a fully qualified electrician.
De-energize the electrical system before connecting the DM08.
Make the electrical connection of the DM08 through the terminal strips in the interior of the display
electronics.
For the separate design, the sensor cable for the electrodes and the magnetic current are required
in addition. They are connected through the terminal strips in the junction boxes of the display
electronics and the sensor.
Connecting cables:
When connecting the DM08, use the following cable depending on the cable lengths:

The cables are each twisted in pairs and shielded. In order to protect the cable from external inter-
ference, the pair wires are covered by an additional, overall shield.
The outer shield is grounded by means of special EMC-compliant cable glands at both ends of the
cable.
IMPORTANT! Potential equalisation required!
Comply with the instructions on Potential equalisation (§ Potential equalisation).
