WARNING!
Read and follow the instructions given in chapter
.
Ignoring the instructions can cause physical injury or death, or damage to the
equipment.
1. Open the door of the inverter module cubicle.
2. Remove the shroud that protects the rotor cable connection busbars and cable
entries.
3. Remove the fans (see the pictures below). Undo the two fastening screws of the fan
collar, push the collar a bit inwards and pull the fan with collar out.
4. When shielded cable is used:
Lead the cables into the inside of the cubicle. Ground a shielded cable 360° at the
lead-through with an EMC cable gland.
•
Connect the cables as follows:
•
Cut the cables to suitable length. Strip the cables and conductors. Fasten the
cable lugs to the conductor ends.
•
Twist the cable shields into bundles and connect to cabinet PE (ground) busbar.
Connect any separate ground conductors or cables to cabinet PE (ground)
busbar.
•
Connect the phase conductors to terminals U2, V2 and W2. See the appropriate
connection diagram above. Tighten the phase conductors and PE to 70 N·m
(50 lbf·ft) torque.
When single-core cables without metal shield are used:
•
Lead the cables into the inside of the cubicle through the IP sealing glands.
•
Connect the phase conductors to terminals U2, V2 and W2, and the PE
conductors to the PE terminal. See the appropriate connection diagram above.
Tighten the phase and PE conductors to 70 N·m (50 lbf·ft) torque.
5. Provide support for the cables whenever necessary.
6. Install the fans removed earlier.
7. Refit the shroud removed earlier and close the door.
8. Connect the generator end of the cable. See the diagrams above and the drawings
below. For minimum radio frequency interference and generator bearing current
ground the cable shield 360° at the lead-through of the generator terminal box, or
ground the cable by twisting the shield as follows: flattened width > 1/5 × length. For
the generator specific instructions, see the manufacturer’s user manual.
