Danger
If a 50 mm wide 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 power units 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.
Danger
The DC link connection cables must be routed in such a way that they are ground-fault and
short-circuit proof in accordance with EN 60204-1.
Caution
The total length of the DC link (including the connection cables) must not exceed 10 m.
