VEGADIS 176 • External indicating and adjustment display without external energy for front panel mounting
47916-EN-170801
5 Connect to the signal circuit
5.1 Preparing the connection
Always keep in mind the following safety instructions:
•
Connect only in the complete absence of line voltage
•
Only connect to a 4 … 20 mA signal circuit with sensor or the
4 … 20 mA signal output of a signal conditioning instrument
The instrument must only be powered by an energy-limited circuit
according to IEC 61010-1.
Caution:
Never connect the VEGADIS 176 directly to a voltage source without
current limitation. Otherwise the instrument can be destroyed by a too
high current.
5.2 Connection technology and steps
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Proceed as follows:
