  8. On the backfeed protection cabinet, remove the front cover. Measure for and verify ABSENCE of voltage with a multimeter probe through the holes in the transparent plate for input in a single mains system or for bypass in a dual mains system.
  9. Remove the inner doors from the UPS. See the UPS installation manual for details.
  10. Remove the transparent plate from the backfeed protection cabinet.
  11. On both cabinets, 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.

    1. Measure for and verify ABSENCE of voltage on PE busbar.
    2. Measure for and verify ABSENCE of voltage on DC busbars (DC+, DC-).
    3. Measure for and verify ABSENCE of voltage on output busbars (L1, L2, L3, N).
    4. Measure for and verify ABSENCE of voltage on input busbars (L1, L2, L3, N).
    5. Only for a dual mains system: Measure for and verify ABSENCE of voltage on bypass busbars (L1, L2, L3, N).
  12. Remove the interconnection busbars between the UPS and the backfeed protection cabinet. Disconnect and remove the power cables from the UPS and the backfeed protection cabinet. See Install Interconnection Busbars and Power Cables in the Backfeed Protection Cabinet and the UPS (380/400/415 V). Save all parts for reinstallation.
  13. Disconnect and remove the backfeed signal cable between the UPS and the backfeed protection cabinet. See Connect the Backfeed Signal Cable Between the Backfeed Protection Cabinet and the UPS for details.
  14. Remove the top bracket and the interconnection screws from the front of the UPS and the backfeed protection cabinet. See Position the Backfeed Protection Cabinet and the UPS without Seismic Anchoring or Install the Seismic Anchoring and Position the Backfeed Protection Cabinet and the UPS for details. Save all parts for reinstallation.
  15. If external sync is present: Remove the transparent protection cover from the external synchronization board 0P4809 in the UPS. Disconnect the signal cables from the external synchronization board 0P4809. See the UPS installation manual for details.
    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.
  16. Disconnect and remove any signal cables from the UPS.
  17. Reinstall the inner doors in the UPS. See the UPS installation manual for details.
  18. If present, remove the front seismic anchoring brackets from the UPS and the backfeed protection cabinet. Save for reinstallation.
  19. Reinstall the transparent plate and the front cover on the backfeed protection cabinet. Close and lock the front door of the backfeed protection cabinet.
  20. Remove the left side panel from the backfeed protection cabinet and install it on the left side of the UPS cabinet.
  21. Close and lock the front door of the UPS. Follow the UPS installation manual to finish decommissioning the UPS.
  22. Raise the feet of the backfeed protection cabinet until the casters have full contact with the floor.
  23. You can now move the backfeed protection cabinet by rolling it over the floor on the casters.
    WARNING
    TIPPING hazard
    • The casters of the backfeed protection cabinet are exclusively for transport on flat, even, hard, and horizontal surfaces.
    • The casters of the backfeed protection cabinet 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 backfeed protection cabinet.
    Failure to follow these instructions can result in death, serious injury, or equipment damage.
  24. If present, remove the rear seismic anchoring bracket from the floor. Save for reinstallation.
  25. For transport over longer distances or in conditions that are not suitable for the casters of the backfeed protection cabinet:
    WARNING
    Tipping hazard
    The backfeed protection cabinet can tip easily. Take appropriate precautions during handling and preparation for transport/shipment.
    Failure to follow these instructions can result in death, serious injury, or equipment damage.
    WARNING
    TIPPING hazard
    For transport over longer distances or in conditions that are not suitable for the casters of the backfeed protection cabinet, ensure:
    • that personnel performing the transport have necessary skill and have received adequate training;
    • to use appropriate tools to safely lift and transport the backfeed protection cabinet;
    • to protect the product against damage by using appropriate protection (like wrapping or packaging).
    Failure to follow these instructions can result in death, serious injury, or equipment damage.

    Transportation requirements:

    • Mount the backfeed protection cabinet in a vertical position in the center of a suitable pallet with minimum pallet dimensions: 1000 mm x 1200 mm. The pallet must be suitable for the weight of the maintenance bypass cabinet: 271 kg.

    • Use appropriate means of fixation to mount the backfeed protection 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 backfeed protection 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 backfeed protection 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.
  26. Perform one of the following:
    • Decommission the backfeed protection cabinet, OR
    • Move the backfeed protection cabinet to a new location to install it.
  27. Only for installing the bacfeed cabinet in a new location: Follow the installation manual to install the backfeed protection cabinet in the new location. See Installation Procedure for installation overview. Startup must only be performed by Schneider Electric.
    DANGER
    hAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
    Startup must only be performed by Schneider Electric.
    Failure to follow these instructions will result in death or serious injury.
