10.6.8 General technical data, 690 V inverters
Property Version
Line voltage
● for systems according to IEC: 500 V … 690 V 3 AC ± 10% (in operation -20% < 1 min)
● for systems according to UL 500 V … 600 V 3 AC ± 10% (in operation -20% < 1 min)
filtered devices only with Slash Rating (600Y/347V AC)
Line supply configurations Grounded TN/TT line supplies or non-grounded IT line supplies
Connecting the line supply and motor (Page 86)
Line impedance No restrictions
Power factor λ > 0.9
Output voltage 0 V 3 AC … 0.95 x input voltage (max.)
Input frequency 50 Hz … 60 Hz, ± 3 Hz
Output frequency 0 … 550 Hz, depending on the control mode
Inrush current < LO base load input current
Overvoltage category ac‐
cording to EN 61800-5-1
III for line supplies
Pulse frequency 2 kHz (factory setting), can be adjusted to 4 kHz
Adjustable in steps of 2 kHz.
Current reduction as a function of the pulse frequency (Page 507)
If you increase the pulse frequency, the inverter reduces the maximum output current.
Short-circuit current
(SCCR) and branch protec‐
tion
Maximum permissible line short-circuit current ≤ 100 kA rms
Minimum required short-circuit current ≥ 10 kA rms
The length of the connecting cable from the line to the inverter may not reduce the minimum
short-circuit current
Branch protection and short-circuit strength according to UL and IEC (https://
support.industry.siemens.com/cs/ww/en/view/109479152)
Braking methods DC braking, compound braking, dynamic braking with integrated braking chopper
Degree of protection ac‐
cording to EN 60529
IP20; must be installed in a control cabinet
Protection class according
to EN 61800-5-1
The inverters are devices with protection class I
Touch protection accord‐
ing to EN 50274
DGUV regulation 3 when used for the intended purpose
Cooling in compliance with
EN 60146
Forced air cooling AF
