Installing Power Cables - AC Power Distribution

Installing Power Cables - AC Power Distribution

When the NIP6860 uses AC power supply, one external AC power chassis is added to the DC power supply system to form an AC power supply system. Four AC power cables are used to connect each AC power chassis to the AC PDF.


Never install power cables when the power is on.

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

  • With the 110 V AC power supply, the NIP6860 must use 110 V dual-live-wire AC input to meet the maximum system power consumption requirements with the full configuration. This is because AC power modules are half-load output with 110 V AC input, which cannot meet system power consumption requirements.

  • As the NIP6860 does not support AC power chassis management, the DB9 interface on the rear of an AC power chassis does not need to connect to the monitoring cable in the installation auxiliary material package.

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

  1. Mark both ends of each power cable using a non-permanent marker.
  2. Connect the ends of AC power cables to the input terminals of the AC power chassis. Connect the other ends of the AC power cables to the AC power supply device.
  3. Connect the ends of DC power cables to the PEM modules on NIP6860. Connect the other ends of the DC power cables to the output terminals of the AC power chassis.
  4. Use cable ties to bind the cables together at 100 mm intervals, fixing the cables along the cabling rack from bottom to top.
  5. 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.
