Wiring Under the Floor (Alternative)
If you are routing power cables under a raised floor to the enclosures, you must provide the
appropriate power cables and equipment for installation, and a licensed electrician must route and
connect the power cables to the PDU circuit breakers. To wire each power cable to an enclosure:
1. Push out a knock-out filler in the floor of the PDU to create an opening for the cable.
2. From the Rack PDU or Rack ATS in each enclosure, thread the appropriate power cable (for
your application) from the enclosure to the PDU.
3. At the PDU, route the cable through the opening you created in step 1 and then up through the
wireway ( , ) at either side of the PDU. This will allow you to connect the cable to the upper
circuit breaker panel.
A licensed electrician must route and connect the power cables for wiring under the
floor.
Make sure all wire connections and circuit breaker connections are properly
torqued.
