Description

Remarks

Circuit breaker of each channel

≥16 A - ≤40 A

For hierarchical power supplying protection, the current of the circuit breaker at the user side should be no less than that of the power module (12.5 A).

Installing Power Cables

  1. Install the power cable terminal.
    Figure 8-13 Power cable terminal installation

  2. Attach temporary labels to both ends of each power cable.
  3. Route power cables along the cable ladder and lay them on the chassis.
  4. Connect one end of each power cable to the corresponding terminal and the other end to the PDF.
    Figure 8-14 Installing Power Cables

  5. Use cable ties to bundle cables every 150 mm upwards from the bottom and fasten the cables to the cable tray.
  6. Attach permanent labels 20 mm from both ends of each power cable.
NOTE:

The distance between power cables, ground cables, and signal cables must be greater than 30 mm.

NOTE:

To ensure that the power cable is as long as required, perform the following steps to install a power cable:

  1. Prepare a power cable a little longer than the distance between the power module and PDF.
  2. Install a terminal on one end of the power cable and connect the terminal to the device.
  3. Route the power cable, bind it to the cable tray, and cut any excess length of the cable. Install a terminal on the other end of the power cable and connect the terminal to the PDF.
