Fig. 18: Wiring of X63 for coupling DC link circuits of up to three
JetMove 208-480
Coupling DC link circuits guarantees equal distribution of load for all internal ballast
resistors. A special ballast circuit ensures that the braking energy which is not used
by an other amplifier is equally distributed among all ballast resistors.
Important!
Requirements on the coupling of DC link circuits:
Before connecting a coupled JetMove 208-480, completely connect all
wires of X63.
Otherwise the device could be damaged!
Do not couple more than three JetMove 208-480.
Do not couple JetMove 208-480 with other amplifier types.
Do not release the other JetMoves 208-480 if one of the coupled
devices is not ready for operation.
The power supplies of coupled JetMoves 208-480 have to be activated
and deactivated simultaneously.
For this reason, please connect the supply lines of the coupled
JetMove 208-480 with exactly the same contactor and the same fuses,
identical cable diameters and cable lengths (difference <0.5 m).
