Safety Information

Risk of electric shock. A hazardous voltage is present for up to 5 minutes after the power
supply has been disconnected.
This time must elapse before any work may be carried-out on the adapter (e.g.
mounting/installation).
When opening the protective cover for the DC link, you must activate the release. A
suitable tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used further, as this could result in secondary damage
or accidents.
It is only permissible to establish connections to the DC link using the adapters that
SIEMENS has recommended (DC link adapter and DC link rectifier adapter).
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.
