Safety information

Danger
Risk of electric shock. A hazardous voltage is present for 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 used, otherwise this could result in secondary damage
or accidents.
Caution
The DC link discharge voltage hazard warning must be affixed to the modules in the local
language.
A set of labels in 16 languages is available under Order No.: 6SL3166-3AB00-0AAx.
With a connected braking resistor, the Braking Module is ground-fault proof.
Notice
The 80 mm clearances above and below the components must be observed.
Caution
It is only permissible to establish connections to the DC link using the adapters that Siemens
has recommended (DC link adapter and DC link infeed 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 startup. After transportation, the screws must be tightened.
