3.7. Commutation choke
In an effort to keep system perturbations as low as possible, the TVD should
always be operated with a commutation choke. See sections 3.3 and 3.4; for
power loss see dimension sheet in section 7.
3.8. DC bus circuit
Use the busbars contained in the connection accessories kit to connect the
drive modules to the TVD's DC bus circuit.
Use twisted single conductors for longer connections (maximum length equals
1 meter).
