Planning the electrical installation
Contents of this chapter
This chapter contains the instructions that you must follow when selecting the generator,
cables, protections, cable routing and way of operation for the converter system.
Note: The installation must always be designed and made according to applicable local
laws and regulations. ABB does not assume any liability whatsoever for any installation
which breaches the local laws and/or other regulations. Furthermore, if the recommendations
given by ABB are not followed, the converter may experience problems that the warranty
does not cover.
Selecting the grid disconnecting device
The converter is equipped with a main circuit breaker as standard. However, the opened
main circuit breaker does not isolate the grid cable terminals of the converter from the grid.
Equip the installation with another disconnecting device placed in between the power grid
and the grid cable terminals of the converter. For example, the main circuit breaker of the
grid transformer could also be used as the extra disconnecting device if it meets the
requirements for a disconnecting device.
