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 to 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� 2 A)�
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�
