Smart Line Modules (5 kW and 10 kW) with cold plate
7.2 Safety Information
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 of line short-circuit power to rated
power must be ≧ 70. If the line short-circuit power is too low, the tripping times increase to
an unacceptable level (e.g. fire is possible).
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 and with the complete system in a no-voltage condition
(powered-down) and with the DC link discharged. After being transported, the screws must
be tightened.
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
lefthand end of the drive line-up, then the DC link bridge including all of the screws must be
removed. It is not permissible to insert the screws without a DC link bridge.
For all other power units and DC link components (e.g. Capacitor Module) that are wider
than 50 mm, it is neither permissible to move the DC link bridge to the left nor remove it.
If this is not carefully observed, this can result in damage and accidents.
In a supply system without regenerative feedback capability (e.g. diesel generator), the
regenerative feedback capability of the Smart Line Module must be deactivated by means
of a jumper between terminals X22.1 and X22.2. The braking energy must then be
dissipated via an additional Braking Module with a braking resistor in the drive line-up.
