Description

The Smart Line Module (SLM) is an unregulated line infeed/feedback unit. The SLM supplies
the Motor Module(s) with an unregulated DC voltage at the DC output. As regards the
current and voltage waveform, the SLM in infeed mode exhibits the typical characteristic of a
6-pulse diode rectifier jumper.
In feedback mode, the current waveform is square waved. Feedback can be deactivated by
means of a terminal because these Smart Lines Modules are not equipped with a DRIVE-
CLiQ connection.
The DC link starts precharging as soon as the supply voltage is applied and is independent
of its phase sequence direction. Load can be applied to the DC link after the modules have
been enabled. An optional main contactor is required for disconnecting the voltage.
Smart Line Modules are suitable for direct operation in TN, IT, and TT systems.
