    Unclip the right battery connector and move the connector out of the way. Pull the battery tray out using the plastic tabs and remove the battery tray (see Figure 13). Figure 13. Removing the Battery Tray If installing additional UPSs, repeat Step 1 for each cabinet. NOTE: The instructions are the same for square-hole racks and unthreaded, round-hole racks.

  • Page 21

    Attach the rails to the rack: Engage the back end of the rail until it fully seats on the vertical rack flange and the hook latch locks in place (see Figure 14). Pull the rail toward the front. Push the front end of the rail until it fully seats on the vertical rack flange and the hook latch locks in place.

  • Page 22

    Slide the cabinet into the rack (see Figure 15). Repeat for any additional cabinets. Figure 15. Installing the Cabinet Secure the front of the cabinet to the rack using the four thumbscrews on the mounting brackets (see Figure 16). Tighten by hand; do not use power tools. Repeat for any additional cabinets. Figure 16.
