InfraStruXure 20kW System: Installation, Operation, and Maintenance 21

Route and Attach Overhead Wiring

Route and attach power cables to equipment racks

If you ordered overhead wiring, connect the prewired power cables of the InfraStruXure 20kW

System as follows:

1. Install the Shielding Troughs, Shielding Partitions, and Cable Ladders so that you can route

power cables from the system to the NetShelter VX Enclosures.

2. Find the numbers that indicate the enclosure to which each power cable will supply power.

These numbers appear on the roof of the InfraStruXure 20kW System where the power cables

exit, and on the ends of each power cable.

3. Beginning with the power cables for the enclosures farthest from the system, run each power

cable within the Shielding Trough along the row and, if necessary, across one or more Cable

Ladders to the enclosure to which it will provide power.

4. Connect the appropriate power cable to APC power management equipment in the enclosure in

one of the four following ways:

– For single-feed devices without redundancy: Attach a power cable directly to a Rack PDU

installed in a NetShelter VX Enclosure.

See the installation and grounding instructions in the manual included with your

Shielding Troughs, Shielding Partitions, and Cable Ladders.

Note

The enclosures are not numbered. Consult your APC InfraStruXure

Configuration Buildout Tool to determine the enclosure associated with each

power cable.

Note

Ensure that the L21-20 twist-lock connector at the end of each power cable

always lies on top of any longer power cables in the Shielding Trough.
