Checking customer power type and DC-UPS input phase selection settings

About this task

Attention: The DC-UPS input phase selection settings must be correct for the type of power provided by the customer. If the setting is not correct, the DC-UPS will not power on.

Procedure

  1. Determine the type of DC-UPS in the rack you are installing:
    Table 1. DC-UPS type by rack model
    Rack model DC-UPS type
    980, 98B, 984, 84E, 985, 85E Single-phase
    982, 98F, 986, 86E, 988, 88E Three-phase
    981, 98E Can be single-phase or three-phase
    Note: If you are unsure whether the rack is configured for single-phase or three-phase power, observe the J3-x PARTNER connectors at the rear of the DC-UPS.
    • A single-phase DC-UPS has two partner connectors: J3-1 and J3-2. See Figure 5.
    • A three-phase DC-UPS has three partner connectors: J3-1, J3-2 and J3-3. See Figure 6.
  2. Determine the customer power type:
    Table 2. Power label colors according to power type
    Customer power type Mainline power cable label and DC-UPS label
    Single-phase (200 - 240 V) 200 - 240 V 1-phase (green) (See Note)
    Three-phase low voltage (200 - 240 V) 200 - 240 V 3-phase (blue)
    Three-phase high voltage (380 - 415 V) 380 - 415 V 3-phase (yellow)
    Note: Single-phase configurations normally use a single-phase DC-UPS, which does not have a colored label.
  3. At the rear of the rack, set the DC-UPS input phase selection cables (P12/P13) for your customer power type.
    1. Use Figure 1 to determine the setting for your customer power type.
    2. Figure 2 shows the phase selection cables that are below the CB1 main line switch.
    3. If the cable setting must be changed:
      1. Loosen the screw  1  (upper left) and open the DC-UPS phase selection cover.
      2. Reconnect P12 and P13 to match the customer power type.
      3. Close the DC-UPS phase selection settings cover and tighten the thumbscrew.
    4. Note the phase setting label color.

  4. Uncoil the mainline power cables from the ship group.
    CAUTION:
    Do not connect the storage facility power cables to customer power until you are instructed in a later installation section.
  5. Locate the DC-UPS connector on the mainline power cables. Observe the label on the rear surface of the connector. Note the label color and the power type. See Figure 3 and Figure 4.

  6. The mainline power cable and DC-UPS input phase setting must match customer power type.
    1. See Table 2.
    2. Do you have the correct mainline power cables?
      • Yes, continue at the next step.
      • No, the DC-UPS will not power on. Stop and resolve the problem.
  7. Continue with the installation according to the type of customer power:
