    8-card Shelf CCC model 751109/15 Ground Connections To connect the ground of the 8-card Shelf The equipment ground must be connected before any other connection AUTION is made to the shelf. Connect the Station ground lug to the Station ground bar or ground rod using a #6 AWG wire - green with yellow stripes.
  • Page 27 HIGH LEAKAGE CURRENT: Earth connection is essential before making AUTION telecommunication network connections. To ensure the safety of personnel, Positron recommends following these guidelines: If the return of the DC supply is grounded, it must be grounded at the source.

The shelf ground lug is the preferred way to ground the shelf. The 751313MC and 751318MC input is protected through the power cord ground wire, but since the ground lug provides better current carrying capacity, it is the preferred way of grounding the shelf.

    Internal Power Supply Figure 9: External Power Supply Internal Power Supply When an internal Power Supply Card, model 751313MC or 751318MC is used, then either 120 Vac or 130 Vdc must be supplied to the shelf via one of the power cables provided.

  • Page 42: Internal Power Supplies Configurations

    8-card Shelf CCC model 751109/15 3.6.1 Internal Power Supplies Configurations When using the internal power supplies, multiple configurations can be used depending on the installation and reliability desired. 1. Where reliability and down time are not a concern or shelf circuits are not critical, a single Power Supply can be used.
  • Page 43 Internal Power Supply know that the system is running on batteries and needs servicing before the batteries are discharged. The operating temperature of the power supplies is -20ºC (-4 ºF) to +65ºC (+149ºF). The battery back-up, 751312 has an operating range of 0ºC (+32ºF) to 50ºC (+122ºF) and therefore reduces the operating temperature range of the whole installation even if all the other cards can operate on a wider range.

  • Page 44: To Install The Power Cable

    8-card Shelf CCC model 751109/15 To install the power cable 1. If the power supply runs off 120 Vac, use the AC power cable (with the plug) provided in the kit. If running off 130 Vdc or 48 Vdc, use the DC power cable (without the plug) provided in the kit.

  • Page 48: Temperature Considerations

    8-card Shelf CCC model 751109/15 Temperature Considerations The 8-card Shelf CCC model 751109/15 enclosure is made of an insulating material, which under normal operating conditions (i.e., shelf closed) results in a higher temperature internally than externally (room temperature). Therefore, special care must be taken to ensure that the internal temperature never exceeds the operating temperature of each card.

    Temperature Considerations 2. Add the power consumption of all cards powered by -24 Vdc. This value represents the “Total Power Consumption” at -24 Vdc. This value is required for the calculation of the power dissipation of the internal power supply. If an external power supply is being used, omit this step.
  • Page 52 8-card Shelf CCC model 751109/15 3. Lower the temperature of the room where the equipment is installed. 4. Use an external power supply to power the shelf. This will reduce the internal power dissipation. For an example of the temperature calculation worksheet for a 8-card Shelf CCC model 751109/15, refer to Table 10 on page 53.
