Siemens SINAMICS S120 Equipment Manual page 175

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 control cabinet is required. Because of the high leakage current of
the Motor Module, a permanent PE connection of the Motor Module or control cabinet is
required.
Furthermore, the following measures must be taken according to EN 61800-5-1:
Either protective ground conductor cross-sections ≥ 10 mm
protective ground conductor of the same cross-section as the first one.
The DC link discharge voltage hazard warning in the local language must be attached to all
of the components.
A set of labels in 16 languages is supplied with the component.
A ventilation clearance of 80 mm above and below the components must be observed.
It is only permissible to establish connections to the DC link using the adapters that
SIEMENS has recommended (DC link adapter and DC link rectifier adapter).
CAUTION
The tightening torque of the DC link busbar screws (1.8 Nm, tolerance: +30%) must be
checked before commissioning when the system is disconnected from the power supply
and the DC link is discharged. After transportation, the screws must be tightened.
For line supplies without regenerative feedback capability (e.g. diesel generator), the
regenerative feedback capability of the Active Line Module must be deactivated by means
of parameters (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.
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 left-
hand end of the drive line-up, the DC link bridge (including the screws) must be removed.
The screws must not be inserted without a DC link bridge.
For all other power units and DC link components (e.g. Capacitor Module) that are wider
than 50 mm, the DC link bridge must be moved to the right and fastened; it must not be
moved to the left or removed.
If this is not carefully observed, this can result in damage and accidents.
