Line Modules Booksize
3.2 Active Line Modules with internal air cooling
If a 50 mm wide Motor Module or if a DC link component with the appropriate width (e.g.
Braking Module, Control Supply Module, Voltage Clamping Module) is located at the left-
hand end of the drive line-up, the DC link bridge (including the screws) must be removed.
The screws must not be inserted without a DC link bridge.
For all other power units and DC link components (e.g. Capacitor Module) that are wider
than 50 mm, the DC link bridge must be moved to the right and fastened; it must not be
moved to the left or removed.
If this is not carefully observed, this can result in damage and accidents.
The DC link side covers are supplied as standard with the components; they can also be
ordered separately, if required (order no.: 6SL3162-5AA00-0AA0).
The total length of all the power cables (motor supply cables and DC link cables) must not
exceed 350 m in Active mode and 560 m in Smart mode.
The total length of all the power cables (motor supply cable and DC link cable) must not
exceed 1000 m in Active Mode combined with Active Interface Module and Basic Line
Filter.
Only cables from Siemens must be used for DRIVE-CLiQ connections.
If the Line Module is not disconnected from the network (e.g. via the main contactor or main
circuit-breaker), the DC link remains charged.
