Power Distribution Principle

NOTE:
  • One PM outputs a maximum of 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.

Installing power cables

Do not install power cables when the power is on.

  1. Install PMs.
    Figure 8-12 Installing PMs

  2. Attach temporary labels to both ends of each power cable.
  3. Route DC power cables along the cable ladder and connect them to the input terminals of the DC power distribution box. Connect the other end of each power cable to the PDF in the equipment room.
  4. After cables are inserted to the terminals, use cable fasteners to secure the cables to the terminals.
  5. Use cable ties to bundle the cables every 150 mm (5.91 in.) upwards from the bottom end, and secure the cables to the cable tray.
  6. Attach permanent labels 20 mm (0.79 in.) from both ends of each power cable.
