Smart Line Modules with cold plate

4.11.1

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. Feedback can be deactivated by
means of a terminal because these Smart Line Modules are not 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.

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 314) 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.
Note
Connected to the public low-voltage network
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 (grid), authorization is required in advance from the local power supply company
(utility company) in the following cases:
• The rated current of the motor ≤ 16 A per conductor.
• The rated motor current does not comply with the requirements specified in EN 61000-3-
2 regarding current harmonics.
