Figure 6.7:
Details of the power arm supply and fiber optic cables installation stages
ATTENTION!
The fiber optic cables must be handled with care so as the material is not crushed, bent or cut. In
order to insert or remove the cables, exert force on the connectors only, never on the fiber.
NOTE!
In order to extract the power cells, follow the procedures described in the previous sections in the
reverse order. Remove the optic cable before removing the cell.
6.2 ELECTRICAL INSTALLATION
6.2.1 Power Section
The power cables that connect the grid input to the MVW3000 and those that connect the inverter panel to the
medium voltage motor (
Figure 6.11 on page 6-14
) must be specific for medium voltage applications and sized
for the rated currents.
