Smart Line Modules with external air cooling

4.9.1

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. An optional main contactor is required for disconnecting the voltage.
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.
