● Limiting the reactive current in the overvoltage range
This limit is only active if the voltage on side 1 or side 2 lies in the overvoltage range.
The side of the DCP with the higher voltage is always considered when determining the
current limit.
Voltages in the overvoltage range that are briefly permitted may only be available for a
maximum of 30 s after switching on or switching off (ON/OFF1).
Otherwise, the device outputs fault F60500 and possibly shuts down.
In this range, the devices can only be operated with reduced current (30 kW device) or
with no current (120 kW device).
The overvoltage ranges of the individual device types are specified in Chapter "Device
data (Page 427)".
