Description

The Smart Line Module Booksize Compact is an unregulated infeed/regenerative feedback
unit. The Smart Line Module supplies the Motor Module(s) with a non-stabilized 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 parameterization because like the Active Line Modules, these Smart Line
Modules are 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.
The Smart Line Module Bookzse Compact can be used with cooling types "internal air
cooling" or "cold plate". The cooling type is selected via parameter p249 "Power section
cooling type".
Smart Line Modules are suitable for direct operation in TN, IT, and TT systems. The Line
Modules have an integrated overvoltage protection function.

Safety information

Risk of electric shock. A hazardous voltage is present for up to 5 minutes after the power
supply has been disconnected.
The protective cover may only be opened after this time has expired.
When opening the protective cover for the DC link, you must activate the unlocking.
A suitable tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used any further. Otherwise this could result in
secondary damage or accidents.
