NOTICE
Damage to the drive electronics when switching the line contactor under load
When switching the line contactor (type according to the recommended selection) under
load, then the contacts will be subject to premature wear. This can cause the contactor to
malfunction, with subsequent damage to the drive electronics.
• Use a leading opening auxiliary contact or use a Voltage Sensing Module (VSM10).
• If this is not possible, then avoid switching the line contactor under load.
NOTICE
Damage through use of incorrect DRIVE-CLiQ cables
Damage or malfunctions can occur on the devices or system when DRIVE-CLiQ cables are
used that are either incorrect or have not been approved for this purpose.
• Only use suitable DRIVE-CLiQ cables that have been approved by Siemens for the
Note
Operation on line supplies where energy recovery is not possible
In line supply systems without energy recovery capability (e.g. a diesel generator), device
faults can occur as the braking energy cannot be dissipated.
• Deactivate the energy recovery function of the Active Line Modules and Smart Line
Modules using parameter p3533.
• The braking energy must then be dissipated via an additional Braking Module with
braking resistor in the drive line-up.
Exception: For 5 kW and 10 kW Smart Line Modules, you must deactivate the energy
recovery function as follows:
• Jumper between terminals X22.1 and X22.2
• Ground at X22.4
Note
Malfunctions due to polluted DRIVE-CLiQ interfaces
Malfunctions can occur in the system through the use of polluted DRIVE-CLiQ interfaces.
• Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.
