Terminal and lead-through data for the generator cable
You can connect cable lugs to both sides of the connection busbar. The lead-throughs are
acquired separately by the customer. Generator cables enter the cabinet at the top of the
cabinet.
Generator cable connection busbars are presented below. See also chapter Dimension
drawings .
Grid specification
Requirements for the grid connection
For applicable grid codes, contact your local ABB representative.
Voltage ( U
1
) 525/550/575/600/660/690 V AC 3-phase for 690 V AC converters. This is
indicated in type designation label as typical input voltage level
(3~ 690 V AC).
± 10% variation from the converter nominal voltage is allowed as default.
Frequency ( f
1
) 50 ± 5 Hz or 60 ± 5 Hz. Maximum rate of change 17%/s.
Maximum allowable
prospective short-circuit
current (IEC 60439-1,
UL 508 C) 75 kA when protected by fuses given under Fuses .
According to UL 508C, the converter is not rated for short-circuits with a
power factor less than 1.
Power factor -1…0…1
Harmonic distortion Total harmonic current distortion (n = 2...40) < 5%.
Total harmonic voltage distortion (n = 2...40) < 5%, when
R
sc
> 7.
