    Disconnecting a C3000 or C5000 DC Power Cable

    To disconnect a power cable for a DC power supply (see Figure 1):

    1. Switch off the dedicated customer site circuit breaker for the power supply being removed.
    2. Make sure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cables might become active during the removal process.
    3. Verify that the status LED on the power supply is not lit.
    4. Remove the power cable from the external DC power source.
    5. Remove the clear plastic shield covering the field-wiring terminals on the power supply.
    6. Remove the screws on the field-wiring and ground terminal.
    7. Carefully move the power cables out of the way.
