Overheating when the total length of the power cables is exceeded
Overheating and fire can result when the total length of the motor cables is exceeded.
• Ensure that the total length of the motor cables does not exceed 300 m.
NOTICE
Damage to additional loads as a result of undesirable line harmonics
Line harmonics can occur if line filters that differ from those listed in this Manual are used.
These can disturb or damage other loads connected to the line supply.
• Only use line filters that are listed in this Manual.
NOTICE
Damage to components by incorrectly connecting the line filter
When incorrectly connecting the line filter, these components can be destroyed or
damaged.
• Only connect the Line Module to the SINAMICS line filter via the associated line reactor
• Connect additional loads upstream of the SINAMICS line filter (if required, via a separate
Note
Motor cable length exceeded
When the maximum motor cable length of 300 m is exceeded, it can no longer be
guaranteed that Class C2/C3 is maintained; for very long motor cables this can mean that the
line-side or motor-side power components can overheat.
Additional information is provided in the Low Voltage Engineering Manual.
Note
Disconnect the line filter for a high-voltage test
If a high-voltage test is conducted with alternating voltage in the system, the existing line
filters must be disconnected in order to obtain accurate measurements.
If a high-voltage test is carried out with DC, the connection clip to the basic interference
suppression module must also be removed in the Smart Line Module (see Chapter Electrical
connection (Page 174)) or in the Active Interface Module (see Chapter Electrical connection
(Page 94)).
