Installing Power Cables - DC Power Distribution

Installing Power Cables - DC Power Distribution

In standard configuration, the NIP6860 has four PEMs. Each PEM requires an NEG DC power cable and an RTN DC power cable. This section describes how to connect power cables to the two DC supply modules.

Context

Never install power cables when the power is on.

Before installing power cables, ensure that the device is adequately grounded.

  • There is a length of copper core inside the cable. Do not connect anything to the core.

  • DC power distribution cables

  • For details, see Guide to Power Distribution Design of the NIP6860.

Procedure

  1. Mark both ends of each power cable using a non-permanent marker.
  2. Connect the M6 JG2 terminals of the DC power cable to the PEMs on the NIP6860. Connect the M8 OT terminals of the DC power cable to the output terminals on the power supply device.
  3. Use cable ties to bind the cables together at 100 mm intervals, fixing the cables along the cabling rack from bottom to top.
  4. Affix permanent labels 20 mm from both ends of each power cable.

Follow-up Procedure

The power cable has polarity. After the device is powered on, if the PEM indicator blinks red, check whether the anode and cathode of the PEM power cable are properly connected. If they are not properly connected, immediately switch off the previous-stage power and properly connect the power cable.

  1. Install a plastic cover on each power module.
  2. The power cables are fixed securely and have sufficient contact with the terminals.
  3. The cables in the corner are unbent.
  4. The power cable labels are filled in and attached to the cables as required. All labels are neat and face the same direction, allowing for easy viewing.
  5. The power cable, ground cable, and signal cable are bound separately. The distance between them must be greater than 3 cm.
