Danger
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.
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.
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 ratio of line short-circuit power to rated power 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).
