12-Pulse Connection, Two Supply Modules In Parallel - ABB ACS800-07-0610-3 Hardware Manual

12-pulse connection, two supply modules in parallel

Notes:
• No parallel cabling (for each module) is shown here.
It is also possible to connect all input power terminals of module 1 to the transformer Y-output and
module 2 to the transformer D-output. Note, however, that then the two bridges inside a single
module do not form a 12-pulse connection any more. This means that the benefits of the 12-pulse
connection are not available during a temporary operation with one module out of use (e.g. for
maintenance).
• Each input terminal of the supply modules must be fed through a dedicated fuse. The fuses are
specified in
• The secondaries of the transformer must not be grounded.
