Page 13: Unpacking The Cabinet
Unpacking the Cabinet CAUTION: Unpacking the cabinet in a low-temperature environment may cause condensation to occur in and on the cabinet. Do not install the cabinet until the inside and outside of the cabinet are absolutely dry (hazard of electric shock). CAUTION: The cabinet is heavy (see page 63). - Page 14 With one person on each side, carefully lift the cabinet out of the outer carton using the handles on the cardboard and set it on a flat, stable surface (see Figure 3). Place the cabinet in a protected area that has adequate airflow and is free of humidity, flammable gas, and corrosion.

Page 17: Rackmount Setup
Rackmount Setup CAUTION: The cabinet is heavy (see page 63): 1) Dell strongly recommends to remove the battery tray from the UPS before lifting. 2) Lifting the cabinets into the rack requires a minimum of two people. CAUTION: Removing the batteries should be performed or supervised by personnel knowledgeable about batteries and the required precautions. - Page 18 Disconnect the battery connector and place the right battery connector in the battery door to move it out of the way. Pull the battery tray out using the plastic tabs and remove the battery tray (see Figure 9). Figure 9. Removing the Battery Tray If installing additional UPSs, repeat Step 1 for each cabinet.
- Page 19 NOTE: The instructions are the same for square-hole racks and unthreaded, round-hole racks. The rails fit both rack styles. The round-hole rack is shown in the illustrations. Select the proper holes in the rail for positioning the cabinet in the desired location in the rack. The rails should be located at the bottom of the 4U space allocated for the UPS or 3U for the EBM.
- Page 20 Attach the rails to the rack (see Figure 11): Adjust the rail so that the flanges fit outside the C-shaped vertical rail. Secure the rail using the supplied #12-24 Phillips head screws (four for each rail). Use the bottom two holes for the front of the rail. Use the second and fourth holes for the back of the rail. NOTE: If the vertical rail has square holes, use a square nut (not supplied) with the supplied #12-24 Phillips-head screw.

Page 27: Installing Remote Emergency Power-Off
If an emergency power-off (disconnect) switch is required by local codes, see the following section, “Installing Remote Emergency Power-off” (REPO) to install the REPO switch before powering on the UPS. Plug the equipment to be protected into the UPS output receptacles, but do not turn on the protected equipment. - Page 28 NOTE: The pins must be open to keep the UPS running. If the UPS shuts down because the REPO connector pins are shorted, restart the UPS by re-opening the REPO connector pins and turning on the UPS manually. Maximum resistance in the shorted loop is 10 ohm. NOTE: Always test the REPO function before applying your critical load to avoid accidental load loss.
