Cable installation

DRIVE-CLiQ cables should be installed according to the same rules specified for signal cables.
Since the cables supplied as standard and available as options have special properties, there is no need to provide
extra shield bonding in the cabinet. The cables should be routed in zones C and D of the cabinet where possible
(refer to the chapter "EMC Installation Guideline).
Openings in the chassis power units for cable entry and connection
Example of how to calculate and route the required DRIVE-CLiQ cables:
In this example, we will use DRIVE-CLiQ cables to connect a drive line-up comprising four Motor Modules in frame
size FX, which are supplied by an Active Line Module with an Active Interface Module in frame size GX. The cabinets
are assembled as shown in the picture below.
The Control Unit must be latched into the lugs provided on the left-hand side of the Active Line Module. The Active
Interface Module must be mounted next to the Active Line Module, but at a distance of ≥ 100 mm so that the Control
Unit connections are still accessible.
The Voltage Sensing Module (in the Active Interface Module) is connected to the Control Interface Board of the
Active Line Module by means of cable [1] which is supplied with the Active Interface Module. The connection
between the Control Unit and the Active Line Module is made with the 0.6 m DRIVE-CLiQ cable [2] which is supplied
with the Active Line Module. The 1.45 m DRIVE-CLiQ cable [3] (supplied with the Active Interface Module) is used to
link the first Motor Module to the Control Unit. The DRIVE-CLiQ cables from the Control Unit to the Active Line
Module and the first Motor Module must be routed through the rubber sleeve on the left-hand side panel of the Active
Line Module. The connections between adjacent Motor Modules are made with the 0.6 m DRIVE-CLiQ-cables [2]
which are included in the accessories pack of each Motor Module in frame size FX.

The DRIVE-CLiQ cable connection and the Control
Unit position are in the center of the power unit on
Chassis models. The cables can be routed directly to
the power unit by side openings on the chassis unit.
The differences in depth of the various frame sizes
must be taken into account. The difference in depth is
about 200 mm.
The picture on the left shows these openings
illustrated by the example of Motor Modules in frame
sizes FX and GX. The cables supplied as standard
with the equipment can be easily routed through
these aperture.
Additional cables may be required, for example, if
they need to be routed over cross-beams or along
other routes. In this case, these cables need to be
calculated and ordered individually.
