 Connect the Ethernet cables (and sensor cable) to the gauge: From the
previous device the cable connected to the <OUT> port has to be con-
nected to the BPG402-SE <IN> port. And the cable from the BPG402-SE
<OUT> port has to be connected to the next device's <IN> port.

 Secure the sensor cable connector using the lock screws.
For operating BPG402-SP via Profibus, an interface cable conforming to the
Profibus standard is required.
If no such cable is available, make one according to the following indications.
Only a cable that is suited to Profibus operation may be used (→  [6], [12]).
