Y04, 3 AC auxiliary voltage not the same as the standard voltage

Category
Other voltages, frequencies
Function
As standard, the cabinet is supplied with an auxiliary voltage of 3-ph 400 V AC, 50 Hz, with
clockwise rotating field, TN or TT line supply and grounded transformer neutral point. If
option V60, line frequency 60 Hz, is selected, the auxiliary voltage must be 3-ph 460 V AC.
Option Y04 should be selected if the 3-AC auxiliary voltage deviates from these values. The
required voltage must be specified in plain text. The auxiliary voltage may not exceed 690 V.
The auxiliary power supply must be protected on the line-side against short-circuit and
overload. Data for the fuses for the auxiliary power supply (supplies) should be taken from
the type and order-specific circuit diagram.
Note
Depending on the particular version, it may be necessary to additionally select options Y01
and/or Y02.
Connection
Is connected up in the manufacturer's factory.
Commissioning
Checking the setting of the transformer circuit breaker
Diagnostics
The signal contact of the assigned transformer circuit breaker is 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).
