Fig. 18: Wiring of X63 for coupling DC link circuits of up to three
JetMove 204-480
Coupling DC links guarantees equal distribution of load for all internal ballast
resistors. A special ballast circuit ensures that the braking energy which is not used
by another amplifier is equally distributed among all ballast resistors.

equirements on the coupling of DC link circuits:
Before connecting a coupled JetMove 204-480, completely connect all
wires of X63.
Otherwise the device could be damaged!
Do not couple more than three JetMove 204-480.
Do not couple JetMove 204-480 with other amplifier types.
Do not release the other JetMoves 204-480 if one of the coupled
devices is not ready for operation.
The power supplies of coupled JetMoves 204-480 have to be activated
and deactivated simultaneously.
For this reason, please connect the supply lines of the coupled
JetMove 204-480 with exactly the same contactor and the same fuses,
identical cable diameters and cable lengths (difference <0.5 m).
