6.2 Safety information
The drive components generate high leakage currents in the protective conductor. The
components must only be operated in control cabinets or in closed electrical operating
areas and must be connected with the protective conductor. To protect against electric
shock, the protective conductor connection at the control cabinet or machine must be
implemented in accordance with one of the following measures:
• Stationary connection and protective conductor connection by means of ≥ 10 mm
• stationary connection and installation of a second protective conductor with the same
• stationary connection and automatic shutdown of the line supply if the protective
• Connection with a plug connector for industrial applications in accordance with
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 cores is not guaranteed. Risk of electric shock.
Cable shields and unused power cable cores (e.g. brake cores) must be connected to PE
potential to prevent capacitive cross-talk charges.
Non-observance can cause lethal shock voltages.
The cooling clearances of 80 mm 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 commissioning. After transportation, the screws must be tightened.
CAUTION
Only cables from Siemens may be used for DRIVE-CLiQ connections.
