Line Modules Booksize
3.4 Basic Line Modules with internal air cooling
The DC link discharge time 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 sufficiently high supply short circuit power is required for tripping the fuses within the
predefined time in the event of a ground fault. The ratio between the line short-circuit power
and the rated power of the Line Module must be ≥ 30. Low system fault values increase the
time to trip beyond permissible levels (e.g. fire possible).
A ventilation clearance of 80 mm above and below the components must be observed.
The Basic Line Modules conduct a high leakage current via the PE conductor. A permanent
PE connection for the Basic Line Module or control cabinet is required due to the high
leakage current of the Basic Line Modules.
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.
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).
The tightening torque of the DC link busbar screws (1.8 Nm, tolerance: +30 %) must be
checked before commissioning is carried out when the system is disconnected from the
power supply and the DC link is discharged. The screws must be tightened after
transportation.
CAUTION
The DC link side covers are supplied as standard with the components; they can also be
ordered separately, if required (order no.: 6SL3162-5AA00-0AA0).
Note
Only Siemens cables should be used for DRIVE-CLiQ connections.
