Terminal 1 supply L+
When using an IEPE input 24 V DC + 20% (Integrated Electronics Piezo
Electric)
The ground GND of the DC supply is directly connected with the ground
GND of the sensor supply� Therefore the SELV criteria have to be met for
the DC supply�
► Protect the supply voltage externally (max� 2A)�
7.2 Connection of the sensors
Adhere to the SELV criteria (safety extra-low voltage, circuit electrically isolated
from other circuits, ungrounded) when the sensors are connected so that no
dangerous contact voltages are applied to the sensor or transferred to the device�
If the DC circuit is to be grounded (e�g� due to national regulations), the PELV
criteria must be adhered to (protective extra-low voltage, circuit electrically isolated
from other circuits)�
Sensor and diagnostic electronics supply are not electrically isolated�
7.3 Ethernet connection
The RJ45 Config socket is used for the connection to the Ethernet� Ethernet
cables can be supplied as accessories, e�g�:
cross-over cable, 2 m, article no� EC2080
cross-over cable, 5 m, article no� E30112
