AC Power Distribution

Power Distribution Principle

  • One PM outputs a maximum of 2700 W or 3000 W power. You can configure PMs based on the required power.
  • PMs work in N+N backup mode. N PMs (N >= 1) are configured on planes A and B, respectively. The PMs are backed up in the pair of A1 and B1, A2 and B2, A3 and B3, and so on.
  • Note that different power sources must be provided for PMs on planes A and B so that one can provide power when the other becomes faulty.
  • To facilitate further expansion, configure the PMs and install power cables in ascending order of PM slot numbers.

Power Distribution Instance

The following table shows the number of PMs required for specific power consumption.

  2. Attach temporary labels to both ends of each power cable.
  3. Route AC power cables along the cable ladder to the chassis.
  4. Connect one end of each power cable to an input terminal of the AC power distribution box and the other end to the PDF.
  5. After cables are connected to the terminals, use cable fasteners to secure the cables to the terminals.
  6. Use cable ties to bundle the cables every 150 mm (5.91 in.) upwards from the bottom and secure the cables to the vertical cable trough.
  7. Attach permanent labels 20 mm (0.79 in.) to both ends of each power cable.
