Electrical connection

The device is suitable for the connection at 10…36 V DC. Pay attention to the correct value of

the power supply voltage. Otherwise the device will be destroyed.
The connection takes place via

spring force terminals for 0.2 … 1.5 mm² conductors.

The input is bipolar and can be connected as needed. The measuring value of the differential
pressure corresponds to the power consumption of the device.
