Warning
A sufficiently high system fault level is required for the fuses to rupture within the predefined
time in the event of a ground fault. If the system fault level is too low, the fuse rupture times
increase to an unacceptable level (e.g. fire is possible).
Caution
The DC link discharge time 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.
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 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.
Danger
If a 50 mm wide Motor Module or if a DC link component with the appropriate width
(e.g. Braking Module, Control Supply Module, Voltage Clamping Module) is located at the
lefthand end of the drive line-up, then the DC link bridge including all of the screws must be
removed. It is not permissible to insert the screws without a DC link bridge.
For all other power units and DC link components (e.g. Capacitor Module) that are wider
than 50 mm, it is neither permissible to move the DC link bridge to the left nor remove it.
If this is not carefully observed, this can result in damage and accidents.
