Note
In certain circumstances, some fault messages may be incorrect (e.g. phase failure L1
although L2 is missing).
Note
When using the 3RW44 soft starter in an IT system with ground fault monitoring: 3RW44,
product version ≤ *E06*
and the PROFIBUS DP communication module must not be used in
this network configuration. 3RW44 soft starters from product version *E07* onwards can be
used in combination with the PROFIBUS DP communication module. However, the phase
voltage values (UL-N) and phase-to-phase voltage values (UL-L) may be displayed
incorrectly on the measured value display of the 3RW44.
Note
PROFINET communication modules can only be used with a product version of *E12* or
later.
