Y03, 3AC auxiliary voltage not available

Category
Other voltages, frequencies
Function
This option should be selected if a 3-phase auxiliary voltage is not available. In this case, the
auxiliary power supply is taken from inside the cabinet in front of the main armature switch of
the armature circuit. The rated input voltage available in the customer's system should be
specified as part of the inquiry or when ordering the system. If the rated input voltage is
neither 3-ph. 400 V AC 50 Hz nor 3-ph. 460 V AC 60 Hz, then option Y04 must be
additionally selected.
Note
Option L22 (no armature commutating reactor) cannot be selected at the same time as this
option! The rated input voltage must be specified.
Note
Options Y03 and Y04 are only available for systems with a rated input voltage of ≤ 690 V.
Connection
The terminal strip -X1 for the auxiliary power supply is omitted.
Diagnostics
The signal contacts of the assigned fuse monitoring are included in the group fault signal
"circuit breaker tripped" in the signaling circuit. This group fault signal is provided as an
isolated contact at terminal strip -X2.1 .2. For details, see the operating instructions for the
SINAMICS DCM Cabinet, Chapter Electrical installation / Other connections (Page 91).
