Destruction of the Smart Line Module for an incorrect switch-on or switch-off sequence
It is essential that a particular switch-on and switch-off sequence is followed 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.
• Observe the "Ready" signal at output terminal X21.1:
– 24 V DC supply X24 ON
– Line contactor ON
– EP signal X21.3 and X21.4 ON
– Wait until precharging has been completed
– "Ready" signal at terminal X21.1 switched to high
– Infeed is ready, pulse enable possible for motors
– Shut drives down
– Cancel pulse enable for motors (OFF1 signal)
– EP signal X21.3 and X21.4 OFF
– Line contactor OFF
– 24 V DC supply X24 OFF
– "Prewarning" signal at terminal X21.2 switches to low
– Shut drives down via the control system
– "Ready" signal at terminal X21.1 switches to low
Pulse inhibit for all the drives supplied by this infeed within 4 ms
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.
