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 customer power type:
    Table 1. 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)
    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)
  2. At the rear of the rack, set the DC-UPS input phase selection cables (P12/P13) for your customer power type. Ensure both DC-UPSs are set the same.
    1. Use Figure 1 to determine the setting for your customer power type determined in step 2.
    2. Figure 3 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.

  3. 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.
  4. 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 4 and Figure 5.

  5. The customer power type, the mainline power cable label and the DC-UPS input phase setting must all match.
    1. See Table 1.
    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.
  6. Continue with the installation according to the type of customer power:
