Converter module lifting device for drive cabinets hardware manual 3AXD50000210268 Manuals for I/O extension modules, fieldbus adapters, safety options etc. You can find manuals on the Internet. See www.abb.com/drives/documents. For manuals not available in the document library, contact your local ABB representative.
One DC feeder unit can contain one single or up to 3 parallel connected strings. Parallel strings must be connected to separate energy storages. Each parallel string must also have its own connection cabling. For more information, contact ABB. Typically, the DC feeder unit is used in marine applications for heave compensation, peak load compensation, propulsion supply in harbors, or energy storing instead of an additional generator.

The installation must always be designed and made according to applicable local laws and regulations. ABB does not assume any liability whatsoever for any installation which breaches the local laws and/or other regulations. Furthermore, if the recommendations given by ABB are not followed, the drive may experience problems that the warranty does not cover.
= Drive DC voltage (in the DC bus) = Drive input voltage (AC) • ABB recommends to measure the energy storage voltage. If the energy storage is a super capacitor, voltage measurement is obligatory unless the capacitor withstands the maximum DC voltage of the drive or contains internal overvoltage protection.
Protecting the energy storage cable ■ ABB equips the DC feeder unit with fuses as standard. The fuses protect the unit and cables in a cable short-circuit situation. The customer (or the system integrator) must equip the energy storage with overload and short circuit protection for the cable.
EMC compliance of the complete installation ■ ABB has not verified that the EMC requirements are fulfilled with external energy storage and its cabling. The EMC compliance of the complete installation must be considered by the customer (or the system integrator).
