  16. If external sync is present on the UPS: 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.

    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.
  23. Remove the front plates and the transparent plates from the transformer cabinets. See Prepare the Transformer Cabinets for Installation for details.
  24. Measure for and verify ABSENCE of voltage on each input/UPS input/bypass/UPS bypass/output busbar in the transformer cabinets before continuing.
    DANGER
    hAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
    Measure for and verify ABSENCE of voltage on each input/UPS input/bypass/UPS bypass/output busbar before continuing.
    Failure to follow these instructions will result in death or serious injury.

    Single Mains

    Dual Mains

  25. Remove the power cables from the transformer cabinets. See Connect the Power Cables in a Single Mains System or Connect the Power Cables in a Dual Mains System for details.
  26. Perform the following on the transformer cabinets to reposition parts to their original position. See Prepare the Transformer Cabinets for Installation for details.

    • Use appropriate means of fixation to mount the transformer 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 transformer 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 transformer 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.
  33. Perform one of the following:
    • Decommission the transformer cabinet, OR
    • Move the transformer cabinet to a new location to install it.
  34. Only for installing the transformer cabinet in a new location: Follow the installation manual to install the transformer cabinet in the new location. See Installation Procedure for Single Mains UPS System or Installation Procedure for Dual Mains UPS System for installation overview. Startup must only be performed by Schneider Electric.
