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.
For detailed instructions on installing and grounding the Cable Ladders see the instruction
sheet included with the cable ladders (990-1576).
Use wide Cable Ladders (12in; 305mm) where many power cables or data cables will run between rows;
use narrow Cable Ladders (6in; 152mm) where few power cables or data cables will run between rows.
The Cable Ladders are 9feet, 8inches 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.
Note: 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.
• 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.
