Note
When using the 3RW44 soft starter in an IT system with ground fault
monitoring: 3RW44, product version  *E06* and the PROFIBUSDP
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-
1
L) may be displayed incorrectly on the measured value display of the
3RW44.

Note

The "Phase currents" display always shows the currents in the supply
OK
3 cable. This means that, if the soft starter is operated in the "Inside delta
circuit" circuit type, the currents measured internally by the soft starter are
extrapolated to the supply cable current (phase current) by a factor of 1.73

and displayed.

Due to asymmetries, the phase currents displayed in the inside delta
circuit may deviate from the currents that are actually running through the
select
supply cables.
