12-pulse connection, two supply modules in parallel

*)
Notes:
*)
Fuses are not required if the input power line is constructed of busbars that withstand the transformer
short circuit current.
**)
No bridging (connecting 1L1 to 2L1, 1L2 to 2L2, and 1L3 to 2L3) is allowed!
There are two separate incoming cubicles – one for terminals 1L1, 1L2 and 1L3, the other for 2L1, 2L2
and 2L3 – if a) the unit is equipped with air circuit breakers, b) the drive is UL listed, or c) the incoming
cubicle is designed for a busbar connection.
The cable lead-through details (number and size of holes), and cable connection details (number and
dimensions of busbars, tightening torque) are given in chapter
connection.
***)
There are no contactors inside the modules when the drive is equipped with air circuit breakers.
