Active line modules with cold plate
5.2 Safety information
A sufficiently high short-circuit power is required for tripping the fuses within the predefined
time in the event of a ground fault. Insufficient short-circuit power increases the time to trip
beyond permissible levels (e.g. fire possible).
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 control cabinet is required. Because of the high leakage current of
the Motor Modules, a permanent PE connection of the Motor Module or control cabinet is
required.
EN 61800-5-1 also stipulates the following precautions:
Either protective conductor cross-sections of ≥ 10 mm
protective conductor of the same size as the first protective conductor.
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.
The cooling clearances 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. After being transported 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 using 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.
