Electrical power network specification
690 V units: 525…690 V AC 3-phase ± 10% (525…600 V AC ± 10% in UL/CSA
installations, or corner-grounded TN systems). This is indicated in the type desig-
nation label as typical input voltage levels (3~ 525/600/690 V AC). Voltage ( U
1
)
TN (grounded) and IT (ungrounded) systems Network type
50/60 Hz, variation ± 5% of nominal frequency Frequency
Max. ± 3% of nominal phase-to-phase input voltage Imbalance
Supply units with main circuit breaker (F255) and without grounding/earthing
switch (without F259): Short-circuit withstand
strength (IEC/EN 61439-1)
Rated peak withstand current ( I
pk
): 143 kA
Rated short-time withstand current ( I
cw
): 65 kA/1 s
All other configurations:
Rated peak withstand current ( I
pk
): 105 kA
Rated short-time withstand current ( I
cw
): 50 kA/1 s
The drive is suitable for use on a circuit capable of delivering not more than
100,000 rms symmetrical amperes at 600 V maximum when the input cable is
protected with class T fuses. Short-circuit current protec-
tion (UL 508A, CSA C22.2
No. 14-13)
Connection: Dy 11 d0 or Dyn 11 d0 Transformer specification
for 12-pulse supply
(IEC 60076-1:2011)
Phase shift between secondaries: 30° electrical
Voltage difference between secondaries: < 0.5%
Short-circuit impedance of secondaries: > 5%
Short-circuit impedance difference between secondaries: ≤ 10% of the percentage
impedance
To avoid a potentially destructive DC voltage level in an earth fault situation,
grounding of the secondaries is not allowed. Static shielding is recommended.

Auxiliary circuit current consumption
Auxiliary circuit current consumption varies depending on the actual drive configuration and
options. Contact ABB for the delivery-specific value.
Efficiency
98.2…98.8% at nominal power level depending on drive type Efficiency
