Safety information

Warning
After disconnecting all the supply voltages, a hazardous voltage will be present in all
components for another 5 minutes. The protective cover must not be opened until this time
has elapsed.
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 12 languages is available using order number: 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
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.
Note
If braking resistors that are not listed in catalog D21.2 are used, they can be destroyed.
Caution
The left and right ends of the DC link busbar of a drive line-up must be fitted with peripheral
covers (order no.: 6SL3162-5AA00-0AA0).
