  7. Reinstall the top front covers on the UPSs and the I/O cabinet.
  8. Remove the gland plates and brush plates from the top front covers.
    1. For installation without conduits: Reinstall the brush plates.
    2. For installation with conduits: Drill holes in the gland plates for conduits, install conduits, and reinstall the gland plates.
  9. Route the signal cables from the external disconnect devices SIB and MBB into the I/O cabinet to the centralized UPS system display interface. Connect the signal cables from the external disconnect devices to the communication terminal block.
    NOTE: The signal cables from the external disconnect devices SIB and MBB are connected to the centralized UPS system display interface in the I/O cabinet for overview purposes only. The signal cables from the external disconnect devices SIB and MBB must also be connected directly to each UPS for operation and control purposes. See Connect the Signal Cables from Switchgear and Third-Party Auxiliary Products for details.
  10. Optional: Route the signal cables from the optional external disconnect devices in the switchgear (output distribution disconnect devices (ODB1, ODB2, ODB3, ODB4, ODB5) and load bank disconnect device (LBB) – if present) into the I/O cabinet to the centralized UPS system display interface. Connect the signal cables from the external disconnect devices to the communication terminal block.
  11. Route the signal cables through the top boxes and into the cabinets. Route the SELV cables separately from the non-SELV cables.
