9.8 DC Bus link (X14)
The DC bus link can be connected in parallel so that the regen power is divided between all
the AKD-C that are connected to the same DC bus link circuit. Every AKD-C must have it's
own power connection to mains voltage, even if the DC bus link is used.
The devices can be destroyed if DC bus link voltages are different. Only devices with mains
supply from the same mains (identical mains phases and voltage) may be connected by the
DC bus link. Use unshielded single cores with a maximum length of 200 mm. Use shielded
cables for longer lengths.
The DC-Bus link cDC/-DC is not short circuit proof. Observe the recommended wire
cross section (
