Warning
A sufficiently high system fault level is required for tripping the fuses 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 Active Line Modules conduct a high leakage current via the PE conductor. Because of
the high leakage current of the Active Line Module, a permanent PE connection of the Active
Line Module or switching cabinet is required. Because of the high leakage current of the
Motor Module, a permanent PE connection of the Motor Module or switching cabinet is
required.
Measures according to EN 61800-5-1 must be taken (e.g. PE conductor (≥10mm
an additional connection terminal for a PE conductor with the same cross-section as the
original PE conductor).
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.
In a supply system without regenerative feedback capability (e.g. diesel generator), the
regenerative feedback capability of the Active Line Module must be deactivated via a
parameter (see Description of Functions). The braking energy must then be dissipated via
an additional Braking Module with a braking resistor in the drive line-up.
