Danger to life through electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• As a minimum, connect cable shields and the cores of power cables that are not used
(e.g. brake cores) at both ends at the grounded housing potential.
Damage caused by overheating as a result of an inadmissible mounting position
If the Active Interface Module is not operated in a vertical position with the line supply
terminals at the bottom, then the component can be damaged.
• Only operate the Active Interface Module in a vertical position with the line connection at
the bottom.
Note
Functional disturbances as a result of line supply disturbances
The devices have b
een tested for standard line supplies according to EN 61800-3. For line
supplies with significant disturbances (e.g. THD > 8
%; very high percentage of switching
kV), the filter of the line-up can be overloaded as a result of the
tional filter power.
Decouple the drive line-ups using suitable measures:
– Using a Basic Line Filter
Use an HFD line reactor with damping resistor instead of an Active Interface Module
