8.2 DC link rectifier adapter for Booksize format
Components for which the recesses for the DC link rectifier adapter have been removed
must no longer be operated without them. If components need to be operated without the
recess and without DC link rectifier adapter, the DC link cover must be replaced.
The DC link discharge voltage hazard warning on the components on which the adapter is
installed must be in the local language.
A set of labels in 16 languages is supplied with the component.
CAUTION
The screw tightening torque (1.8 Nm, tolerance +30 %) for securing components to the
module-side DC link busbar must be checked before commissioning to ensure that it is
correct. After transportation, the screws must be tightened.
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.
CAUTION
To ensure safe electrical separation, the 24 V supply cables and those for the DC link
connection cables must be physically separated (> 100 mm), or the 24 V cables must be
doubly insulated (e.g. light plastic-sheathed cable).
The DC link connection cables must be routed in such a way as to ensure that they are
ground-fault and short-circuit proof in accordance with DIN/VDE 0100 or suitable fuse
protection must be provided.
CAUTION
The total length of the DC link (including the connection cables) must not exceed 10 m.
