Version: 5.9
If the EL30x1/EL30x2 or EL31x1/EL31x2 terminals have no external GND
int
connection, the GND
int
potential
can adjust itself as required (referred to as "floating"). Please note that for this mode reduced measuring
accuracy is to be expected.
Example 1a
Accordingly, this also applies if the floating point GND
INT
is connected to another potential.

Example 2
The same EL3012 is now again connected with the two 20 mA sensors, although this time with one low-side
measurement at 5 V and one high-side measurement at 12 V. This results in significant potential differences
U
CM
> 10 V (applicable to EL30xx) between the two channels, which is not permitted.
