CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
NOTE!
Cares withApplication:
The use of the line reactance or DC choke is mandatory to limit
the inrush current when the network is reestablished.
NOTE!
ThefunctionRide-Through inVectorModefor models107Ato472A/
500-690 V and 100 A to 428 A/660-690 V works only up to a
maximum time of 2 s. In these models the control power supply is
not fed from the DC Link, it is a separate power supply with 2 s
autonomy.
NOTE!
To activate the Ride-Through, the line supply must fall to a value
lower than (P321

1.35).
