3.8 Smart Line Modules (5 kW und 10 kW) with external air cooling
In a supply system without regenerative feedback capability (e.g. diesel generator), the
regenerative feedback capability of the Smart Line Module must be deactivated by means
of a jumper between terminals X22.1 and X22.2. The jumper is only effective if X22.4 is
also connected to ground. 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 the power cables (motor supply cables and DC link cables) must not
exceed 350 m (shielded).
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 unit. 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.
Note
The mounting frames can only be used if the cabinet has an unpainted metal surface.
NOTICE
Operation without the line reactor is not permissible.
CAUTION
The DC link side covers are supplied as standard with the components; they can also be
ordered separately, if required (order no.: 6SL3162-5AA00-0AA0).
Note
Smart Line 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.
When connecting a machine with integrated Smart Line Modules to the public low-voltage
line supply, authorization is required in advance from the local power supply company (utility
company) if
• the rated current of the machine ≤ 16 A per conductor, and
• the rated machine current does not comply with the requirements specified in EN 61000-
296
