Installation Procedures: Install Shielding Troughs, Shielding Partitions, and Cable Ladders

Shielding Partitions. There are two types of Shielding Partitions, each of which forms a side wall
of a trough for data cables. You can customize the width of the trough for each row of your system —
wider for rows carrying many data cables, narrower for rows carrying fewer.
Cable Ladders for overhead wiring across rows
After installing the Shielding Troughs and Shielding Partitions, install the Cable Ladders between
rows of enclosures. You can also run Cable Ladders across Shielding Troughs in the same row, using
the hardware provided in the ladder kit.
Use wide Cable Ladders (305 mm) where many power cables or data cables will run between rows;
use narrow Cable Ladders (152 mm) where few power cables or data cables will run between rows.
The Cable Ladders are 2946 millimeters long. You can adjust the length of the Cable Ladders in the
following ways:
• Cut the ends with a hacksaw to shorten them.
• Insert the connectors only partially into the side rails to extend them.
• As the back wall, use a Shielding Partition that
contains an opening for routing data cables.
• As the front wall, use a solid Shielding Partition to
hide data cables for a clean appearance.

For more information on installing the Cable Ladders, see the instruction sheet included
with the cable ladders (990-1576).
Do not change the spacing between rows or the length and position of the Cable
Ladders from the layout you planned with your APC representative when you placed
your order. For overhead wiring, each PDU power cable is provided at a pre-determined
length. Changes to the physical configuration of your system could cause some PDU
power cables to be too short or too long.
