Caution
The tightening torque of the DC link busbar screws (1.8 Nm, tolerance: +30%) must be
checked before startup when the system is disconnected from the power supply and the
DC link is discharged. After transportation, the screws must be tightened.
In a supply system without regenerative feedback capability (e.g. diesel generator), the
regenerative feedback capability of the Active Line Module must be deactivated via a
parameter (see Description of Functions). The braking energy must then be dissipated via
an additional Braking Module with a braking resistor in the drive line-up.
Caution
The total length of all the power cables (motor supply cables and DC link cables) must not
exceed 350 m in active mode.
Caution
Only cables from Siemens must be used for DRIVE-CLiQ connections.
Notice
The external air cooling can cause the fans and the heat sink to become heavily
contaminated, which may trigger the temperature monitor in the power section. The fans and
heat sink must be checked for contamination at regular intervals and, if necessary, cleaned.
Note
After installation, the seal on the rear of the device must be checked to ensure that it is tight.
Additional sealing can be used, if necessary.
Caution
The ratio of the short-circuit power to the rated power of the Line Module must be ≥ 70.
Caution
The left and right ends of the DC link busbar of a drive line-up must be fitted with peripheral
covers (order no.: 6SL3162-5AA00-0AA0).
Warning
If the Line Module is not disconnected from the network (e.g. via the main contactor or main
circuit-breaker), the DC link remains charged.
