6.1.2 Safety information
DANGER
Risk of electric shock. A hazardous voltage is present for up to 5 minutes after the power
supply has been switched-off.
It is only permissible to open the protective cover after this time has expired.
WARNING
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 further used. If this is not carefully observed, it can
result in subsequent damage and accidents.
DANGER
The DC link discharge voltage hazard warning in the local language must be attached to all
of the components.
A set of labels in 16 languages is supplied with the component.
With a connected braking resistor, the Braking Module is ground-fault proof.
WARNING
A ventilation clearance of 80 mm above and below the components must be observed.
DANGER
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).
CAUTION
The connection to the braking resistors must be made using a shielded cable.
The tightening torque of the DC link busbar screws (1.8 Nm, tolerance +30 %) must be
checked before commissioning. After being transported the screws must be tightened.
Note
If braking resistors that are not listed in catalog D21.1 are used, they can be destroyed.
