4 driver interface and
controller board
Finally, the installation altitude of the SKiiP 4 depends on:
•
Grid configuration (star grounded grid, delta grounded grid)
•
The voltage level of the line to earth voltage (rated isolation voltage)
•
The overvoltage category (II or III)
•
Whether safety isolation is required or not
