NOTICE
Material damage caused by loose power connections
Insufficient tightening torques or vibration can result in faulty electrical connections. This
can cause fire damage or functional faults.
• Tighten all power connections with the specified tightening torques, e.g. line supply
connection, motor connection, DC-link connections.
• Check the tightening torques of all power connections at regular intervals and tighten
them when required. This applies in particular after transport.
• In the case of plug-in power terminals, check that the interlock of the connectors on the
converter housing is intact.
Note
Malfunctions on non-Siemens equipment caused by high-frequency faults in residential
environments
In the first environment, Category C2 according to EMC product standard IEC 61800
-3
(residential, commercial and industrial sector), the device may cause high
-frequency
disturbance, which can result in malfunct
ions in other equipment.
•
Have the installation and commissioning with appropriate radio interference suppression
measures preformed by qualified personnel.
Note
Connection approval for Power Modules ≤ 16 A per conductor
Power Modules have been designed for use in the industrial environment and generate
current harmonics on the line side as a result of the rectifier circuit.
Machines with built
-in Power Modules ≤ 16 A per conductor must meet the current
harmonics requirements of EN 61000
-3-2 to be connected to the public low-voltage power
system.
If they do not, a connection approval must be applied for from the competent power utility.
Note
For a UL
-approved system use UL-approved cables only.
