•
Shield the energy storage cabling completely, either by using shielded cable or a
metallic enclosure. Unshielded single-core cable can only be used if it is routed
inside a cabinet that efficiently suppresses radiated emissions.
•
Install the cables away from other cable routes.
•
Avoid long parallel runs with other cables. The minimum recommended separation
distance for parallel cabling is 0.3 m (1 ft).
•
Cross other cables at right angles.
Keep the cable as short as possible in order to minimize the radiated emissions.
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).
Parallel connection
One DC feeder unit can contain one single or up to 3 parallel connected strings.
Parallel strings must have separate energy storages. Each parallel string must also
have its own connection cabling.
