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.
Warning
A sufficiently high short-circuit power is required for tripping the fuses within the predefined
time in the event of a ground fault. Insufficient short-circuit power increases the time to trip
beyond permissible levels (e.g. fire possible).
Caution
The DC link discharge time 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.
Notice
The 80 mm clearances above and below the components must be observed.
Caution
The tightening torque of the DC link busbar screws (1.8 Nm, tolerance: +30%) must be
checked before startup when the system is disconnected from the power supply and the
DC link is discharged. After transportation, the screws must be tightened.
