3.2 Active Line Modules with Internal Air Cooling
Warning
The Active Line Modules conduct a high leakage current via the PE conductor. Because of
the high leakage current of the Active Line Module/Motor Module, a permanent PE
connection of the Active Line Module/Motor Module or the control 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.
Caution
The 80 mm clearances above and below the components must be observed.
For the 80 kW and 120 kW Active Line Modules, a ventilation clearance of 50 mm must be
observed in front of the fan.
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.
