Connecting the power supply and signal cables

Connecting-up the power supply and signal cables
The connecting cables for 24 V DC and 230 V AC to supply the left-hand sub-cabinet with
power and for the signal cables must be connected. Depending on the installed options, this
will involve up to 3 connecting cables that must be connected from the right-hand sub-
cabinet (cabinet panel +H.A25) to the lower connector sections in the left-hand sub-cabinet
(cabinet panel +H.A24):
1. Connecting cable with the connector designation –X97 in the lower connector section –X97.
2. Connecting cable with the connector designation –X98 in the lower connector section –X98.
3. Connecting cable with the connector designation –X99 in the lower connector section –X99.
The cables must be routed so that the connecting cables are not disturbed by interference
from the power cables.
To achieve this, the cables should be routed along the PE busbar in cabinet panel +H.A49
and then along the cabinet frame up to the respective connection points.
4.7.4

Connecting the DRIVE-CLiQ topology

Connecting-up the DRIVE-CLiQ topology
The DRIVE-CLiQ connection from the Control Unit (cabinet field +H.A25) to the Power
Module in the left-hand sub-cabinet (cabinet field +H.A49) must be established.
The connecting cable (cable number –W003) is inserted in the factory in the DRIVE-CLiQ
socket –X100 of the Control Unit (in cabinet panel +H.A25), and must be inserted in the
DRIVE-CLiQ socket –X400 of the Power Module in the left-hand sub-cabinet (cabinet panel
+H.A49). The cables must be routed so that the DRIVE-CLiQ connection is not disturbed by
interference from the power cables.
To achieve this, the cables should be routed along the PE busbar in cabinet panel +H.A49
and then along the cabinet frame up to the DRIVE-CLiQ socket -X400.
4.8 Power connections
Swapping the input and output terminals can destroy the device!
Swapping or short-circuiting the DC link terminals can destroy the device!
The contactor and relay operating coils that are connected to the same supply network as
the device or are located near the device must be connected to overvoltage limiters (e.g.
RC elements).
The device must not be operated via a ground-fault circuit interrupter (EN 61800-5-1).
