    DANGER
    Hazard of electric shock, explosion, or arc flash
    • Do no remove any other plates or panels while there is power on the system.
    • Before any work activity is started it, must be confirmed with measurements directly on the terminals that no power is present.
    Failure to follow these instructions will result in death or serious injury.
  8. On the maintenance bypass cabinet, measure for and verify ABSENCE of voltage with a multimeter probe through the holes in the transparent plate for input, bypass, output, neutral, and DC.
    DANGER
    Hazard of electric shock, explosion, or arc flash
    Measure for and verify ABSENCE of voltage with a multimeter probe through the holes in the transparent plate for input, bypass, output, and DC.
    Failure to follow these instructions will result in death or serious injury.
    NOTE: The circuit breakers in GVLMBCA250K500G are 3-poled and do not have a neutral connection.

  10. Open the inner door of the UPS.
  11. On the UPS, measure for and verify ABSENCE of voltage on each input/bypass/output/DC busbar before continuing.
    DANGER
    hAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
    Measure for and verify ABSENCE of voltage on each input/bypass/output/DC busbar before continuing.
    Failure to follow these instructions will result in death or serious injury.
  12. Remove the busbars and insulator parts that connect the UPS to the maintenance bypass cabinet. See Install Busbars Between the UPS and the Maintenance Bypass Cabinet in Single Mains System or Install Busbars Between the UPS and the Maintenance Bypass Cabinet in Dual Mains System for details. Save all parts for reinstallation.
  13. Remove the top bracket and the screws in the front that interconnect the UPS and the maintenance bypass cabinet externally. Remove the two special screws that interconnect the UPS and the maintenance bypass cabinet internally. See Interconnect the UPS with the Maintenance Bypass Cabinet for details. Save all parts for reinstallation.
  14. If external sync is present: Remove the transparent protection cover from the external synchronization board 0P4809. The external synchronization board 0P4809 is located on the rear of the front plate. Disconnect the signal cables from the external synchronization board 0P4809.
    DANGER
    HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
    Check for absence of voltage for all three signal terminals on the external synchronization board 0P4809. When the external synchronization cables are installed, the terminals on the external synchronization board 0P4809 may be energized. Disconnect the fuse disconnector device at the source before removing the transparent protection cover.
    Failure to follow these instructions will result in death or serious injury.

  15. Close the inner door of the UPS and reinstall the screws.
  16. Disconnect and remove any signal cables from the UPS.
  17. Remove the seismic front anchoring bracket/front transportation bracket from the UPS and the maintenance bypass cabinet. Save for reinstallation.
  18. Close and lock the front door of the UPS.
  19. Raise the feet of the UPS until the casters have full contact with the floor.
  20. Move the UPS out of the way of the maintenance bypass cabinet by rolling it on the casters.
    WARNING
    TIPPING hazard
    • The casters of the UPS are exclusively for transport on flat, even, hard, and horizontal surfaces.
    • The casters of the UPS are intended for transport over short distances (i.e. inside the same building).
    • Move at a slow pace and pay close attention on the floor conditions and the balance of the UPS.
    Failure to follow these instructions can result in death, serious injury, or equipment damage.
  21. Remove the right side panel from the maintenance bypass cabinet.

  22. Measure for and verify ABSENCE of voltage on each input/bypass/output/DC busbar in the maintenance bypass cabinet before continuing.
    DANGER
    hAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
    Measure for and verify ABSENCE of voltage on each input/bypass/output/DC busbar before continuing.
    Failure to follow these instructions will result in death or serious injury.

    • Use appropriate means of fixation to mount the maintenance bypass cabinet to the pallet.

    • The original shipping pallet in combination with the original transportation brackets can be reused, if in undamaged condition.

    DANGER
    TIPPING hazard
    • The maintenance bypass cabinet must be appropriately fixed to the pallet immediately after being placed on the pallet.
    • The fixation hardware must be strong enough to withstand vibrations and shocks during loading, transport, and unloading.
    Failure to follow these instructions will result in death or serious injury.
    WARNING
    Unexpected equipment behavior
    Do not lift the maintenance bypass cabinet with a forklift/pallet truck directly on the frame as it may bend or damage the frame.
    Failure to follow these instructions can result in death, serious injury, or equipment damage.
  30. Perform one of the following:
    • Decommission the maintenance bypass cabinet, OR
    • Move the maintenance bypass cabinet to a new location to install it.
