Connecting the generator cables
Connection diagram
Connection procedure
WARNING!
See and obey the safety instructions of the converter. If you ignore
them, injury or death, or damage to the equipment can occur.
WARNING!
Apply grease to stripped aluminum conductors before attaching them
to non-coated aluminum cable lugs. Obey the grease manufacturer’s instructions.
Aluminum-aluminum contact can cause oxidation in the contact surfaces.
1. Open the door of the generator cable connection cubicle (see figures on the next
page).
2. Remove the shroud that protects the generator cable connection busbars and cable
entries.
3. Ensure that foreign objects (screws, etc.) cannot fall inside the converter module.
During installation, cover the top of the module with plastic, fabric etc.
WARNING!
Foreign objects inside the converter module can cause eg, short-
circuit. Injury or death, or damage to the equipment can occur.
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 (to be supplied by the customer).
•
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 the cabinet PE (ground)
busbar. Connect any separate ground conductors or cables to the 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 a 120 N·m
(89 lbf·ft) torque.
