7.6.1.2. Preparing the cable spacers
Cable spacers must be mounted on the busbars in order to guarantee the minimum
required clearance between different potentials, such as busbars, cable lugs or
screws.

cable ties (B)
If the data sheet for the drive specifies the cable entry direction (ie, 'bottom';
'top'), the drive is delivered with the cable spacers installed in the correct
locations; otherwise, the factory-installed cable spacers must be moved to their
correct locations on-site. These locations, which depend on the way the motor-side
and line-side cables are routed, are shown in the mechanical drawing of the drive,
ie, 3BHL000886 E02.
NOTE – For cables with twin hole cable lugs, install the cables first, then install the
cable spacers over the attached cables.
7.6.1.3. Determining the cable length
1.
Determine the required length of a cable between the point of entry and the
connection point inside the cabinet.
2.
Cut the cable to the required length before connection.
7.6.1.4. Best practices and cable routing
–
Do not block access to the optional grounding studs when routing the cables.
–
Use plastic cable ties, which you can insert through designated holes on the
cable spacers (Fig. 7
8), to hold the cables in place.
–
Install the cables starting at the back of the drive and move toward the front.
