Active line modules with cold plate
5.2 Safety Information
Caution
The Active Line Modules conduct a high leakage current via the PE conductor. Because of
the high leakage current of the Active Line Modules, a permanent PE connection of the
Active Line Module or switching cabinet is required. Because of the high leakage current of
the Motor Modules, 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 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. 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.
Caution
The total length of the power cables (motor supply cables and DC link cables) must not
exceed 350 m in active mode.
Caution
Only cables from Siemens must be used for DRIVE-CLiQ connections.
Caution
The left and right ends of the DC link busbar of a drive line-up must be fitted with peripheral
covers (order no.: 6SL3162-5AA00-0AA0).
