Note
Connected to the public low-voltage network
Smart Line Modules have been designed for use in the in
dustrial 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.
Switch-on/switch-off sequence for 5 kW and 10 kW Smart Line Modules
It is essential that the subsequently described switch-on and switch-of sequence 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 destroyed.
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
