Installing PGND Cables and Power Cables (Applicable to FR42612L Cabinets)

Installing PGND Cables and Power Cables (Applicable to FR42612L Cabinets)

Install PGND cables and power cables to carry power for components in cabinets.

Prerequisites

  • Cabinets have been installed.
  • The power switches of output terminals on the power distribution cabinet (PDC) are set to OFF.
  • All circuit breakers on the cabinet PDU are set to OFF.
  • Required materials have been prepared, including power cables, PGND cables, cable ties, wax strings, and PVC insulation tapes.
  • Required tools have been prepared, including diagonal pliers, cable cutters, Phillips screwdrivers, multimeters, and ladders.

Context

PDU connectors are the IEC60309-32A-compliant standard plug and socket, as shown in Figure 5-36. The connector used to connect to the PDU is a male plug, which has been connected to the PDU power cable before delivery. The connector used to connect to a PDC is a female socket. On the installation site, you need to connect the AC power cable of the PDC to the female socket and then connect the male plug to the female socket.

Figure 5-36 PDU connectors

Procedure

  1. Route PGND cables and power cables.

    1. Read Site Survey Report to determine the layout, route, and length of PGND cables and power cables.
      NOTE:

      A cabinet supports both overhead and underfloor cabling. This section uses overhead cabling as an example to illustrate how to route cables.

    2. Use a cable cutter to cut off a piece of cable, and reserve a proper length, as shown in Figure 5-37.
      Figure 5-37 Cutting a cable

    3. Attach temporary labels to both ends of the cable for identification.

      The content on temporary labels can be either customized or be the same as that on engineering labels.

    4. Route PGND cables and power cables neatly along a cable tray, and keep them a proper distance from terminals to which they are to be connected.

  2. Install terminals for PGND cables and power cables.

    NOTE:

    For details about how to prepare terminals for PGND cables and power cables, see Preparing Cables and Connectors.

  3. Install PGND cables.

    1. On the ground bar of a PDC, use a Phillips screwdriver to remove screws from ground terminals. Then, fix PGND cables, as shown in Figure 5-38.
      Figure 5-38 Fixing PGND cables on the ground bar

      NOTE:

      The tightening torque must match with the OT terminal specifications.

    2. Use a Phillips screwdriver to unfasten the terminal screw on the top or bottom of the cabinet mounting bar and fasten the other end of the PGND cable to the mounting bar.
      • In overhead cabling, fasten the other end of the PGND cable to the ground terminal on the top of the cabinet mounting bar.
      • In underfloor cabling, fasten the other end of the PGND cable to the ground terminal on the bottom of the cabinet mounting bar.

  4. Lift the cabinet cover to an angle of approximately 30 degrees and take out the PDU connectors.

    Two persons are advised to complete the preceding step.

    1. Pull the positioning pins on the cover of the rear cabinet door slightly and push the cabinet cover upwards to an angle of approximately 30 degrees, as shown in step 1 of Figure 5-39.
    2. Lead the two PDU connectors out of the two cable outlets on the cabinet cover, as shown in step 2 of Figure 5-39.
    3. Restore the cabinet cover.
    Figure 5-39 Taking out PDU connectors

  5. Connect a power cable to the PDU female socket.

    The power switch of the PDC for providing power for the cabinet must remain off to prevent fatal personal injury.

    1. Separate the male plug from the female socket, as shown in step 1 of Figure 5-40.
    2. Unlock the buckle in the middle of the female socket and disassemble the female socket by spinning it counterclockwise, as shown in step 2 of Figure 5-40.
    3. Route the power cable through the PDU female socket and connect a live line (brown), PGND cable (yellow and green), and neutral wire (blue) respectively to the L/+ jack, jack, and unidentified jack. Use a Phillips screwdriver to fasten the screws on the female socket to secure those lines, as shown in step 3 of Figure 5-40.
    4. Assemble the two parts of the female socket and insert the male plug to the female socket, as shown in step 4 of Figure 5-40.

  6. Connect the other end of the power cable to the wiring terminal of the uninterruptible power system (UPS), AC PDC, or AC distribution box, as shown in Figure 5-41.
