Siemens SINAMICS S120 Equipment Manual page 321

A ventilation clearance of 80 mm above and below the components must be observed.
For the 132 A and 200 A Motor Modules, a ventilation clearance of 50 mm must be
observed in front of the fan.
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 transportation, 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 left-
hand end of the drive line-up, the DC link bridge (including 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.
Cable shields and unused power cable conductors (e.g. brake conductors) must be
connected to PE potential to prevent capacitive cross-talk charges.
Non-observance can cause lethal shock voltages.
It is essential to apply the shield for the motor holding brake. Furthermore, only Motion-
Connect cables must be used for integrated motor holding brakes, as otherwise insulation
of the wires is not guaranteed. Risk of electric shock.
CAUTION
Only cables from Siemens must be used for DRIVE-CLiQ connections.
