8.4 Arrangement of components and devices
A ventilation clearance of 100 mm must be maintained around the line reactor (not including
the mounting surface).
Arrangement of the Voltage Clamping Module:
Line Modules up to 36 kW:
Line Modules above 55 kW:
When retrofitting:
Note regarding the use of modules with a width of 50 mm
Danger
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
lefthand end of the drive line-up, then the DC link bridge including all of the screws must be
removed. It is not permissible to insert the screws without a DC link bridge.
For all other Line Modules and DC link components (e.g. Capacitor Module) that are wider
than 50 mm, it is not permissible to remove the DC link bridge.
If this is not carefully observed, this can result in damage and accidents.
Figure 8-4
The DC link bridges must be removed by unscrewing the M4 screws.
