Parallel connection of Active Line Modules to increase power rating
Active Line Modules are available for creating drive assemblies with more power. These
modules can be operated in parallel on a common Line Connection Module and are
arranged to the right and left of the Line Connection Module. The power connections on the
Active Line Module on the left of the Line Connection Module are a mirror image (device
order number with C in the third-to-last position, example: 6SL3730-7Tx41x-xCU3), which
produces a very compact design for the supply infeed.
The following rules must be observed when connecting Active Line Modules in parallel:
● Up to four identical Active Line Modules can be connected in parallel.
● A common Control Unit is required whenever the modules are connected in parallel.
● Special Line Connection Modules are available for connecting the modules in parallel.
● With multiple infeeds, power must be supplied to the systems from a common infeed
point (i.e. the modules cannot be operated on different supplies).
● A derating factor of 5 % must be taken into consideration, regardless of the number of
modules connected in parallel.

General information

This section describes only those interfaces in the cabinet unit that require additional
connection work by the customer. All other interfaces are pre-wired at the factory and are not
designed for customer connections.
Note
Additional information
All connections to be established on the plant side as well as the interfaces for integration
into the plant control system are described in the circuit diagrams and terminal diagrams on
the customer DVD supplied with the device.
