Description

The Smart Line Module is a non-regulated infeed/regenerative feedback unit. The Smart
Line Module supplies the Motor Module with a non-regulated DC voltage at the DC output. In
the infeed mode the Smart Line Module exhibits the typical current and voltage waveforms of
a 6-pulse diode rectifier bridge.
In feedback mode, the current waveform is square waved. Regenerative feedback can be
deactivated if required. On 5 kW and 10 kW Smart Line Modules, this is done via a terminal,
since these modules do not feature a DRIVE-CLiQ connection. On 16 kW to 55 kW Smart
Line Modules, regenerative feedback can be deactivated via parameters, as, just like Active
Line Modules, these modules are equipped with a DRIVE-CLiQ connection.
The DC link starts precharging as soon as the line voltage is applied and is independent of
its phase sequence direction. Load can be applied to the DC link after the module has been
enabled.
A line contactor can be installed on the line side if the system has to be electrically isolated
from the line supply.
Smart Line Modules are suitable for direct operation on TN, IT and TT systems. The Line
Modules have an integrated overvoltage protection function.
External air cooling uses the "through-hole" method. This is a cooling method that is only
available for SINAMICS booksize units. The Smart Line Module and its heat sink can be
inserted in a rectangular knockout at the rear of the control cabinet and mounted with a seal.
The heat sink and the fan (included in the scope of supply) project beyond the rear of the
control cabinet and the heat is dissipated outside the control cabinet or in a separate air
duct.

NOTICE
Destruction of the Smart Line Module for an incorrect switch-on or switch-off sequence
It is essential that an appropriate switch-on and switch-of sequence (Page 287) is complied
with in order to control the 5 kW and 10 kW Smart Line Modules; if this sequence is not
observed, the Smart Line Module could be damaged beyond repair.
• Comply with the specified switching sequence.
