3.2 Safety information
The drive components generate high leakage currents in the protective conductor. The
components may only be operated in control cabinets or in locked, electrical equipment
rooms. They must be connected with the protective conductor. To protect against electric
shock, the protective conductor connection at the control cabinet or system must be
implemented in accordance with one of the following measures:
• Fixed connection and protective conductor connection with ≥ 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 mandatory that the shield for the motor holding brake is connected. Motion-Connect
cables must be used for the integrated motor holding brake, as otherwise the insulation
strength 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.
Cooling clearances
The 80 mm clearances above and below the components must be observed.
CAUTION
Connection for temperature sensors
Connecting cables to temperature sensors must always be installed with shielding. The
cable shield must be connected at both ends and over a large surface area. Temperature
sensor cables that are routed together with the motor cable must be twisted in pairs and
shielded separately.
CAUTION
The total length of the power cables (motor feeder cables etc.) must not exceed 175 m.
CAUTION
Only cables from Siemens may be used for DRIVE-CLiQ connections.
