Page 14: 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: Installing or removing the battery trays should be performed or supervised by personnel knowledgeable about batteries and the required precautions. - Page 15 (see Figure 5). NOTE: The Dell Online Rack UPS 10 kW Getting Started Guide provides unpacking and installation procedures. To refer to it, remove it from the accessory box before you set the accessory boxes aside.
- Page 16 Remove the top Styrofoam section and set it on a flat, stable surface nearby (see Figure 6). Figure 6. Removing the Top Styrofoam Section NOTE: The battery retaining brackets are labeled L (left) and R (right) to indicate where they must be installed. Remove both battery retaining brackets from the UPS (see Figure 7): Locate the left (labeled L) retaining bracket.
- Page 17 Ensure all battery connectors are disconnected. CAUTION: The batteries are heavy (32 kg/71 lb). Use proper lifting techniques when removing the batteries. Remove the battery trays from the UPS (see Figure 8): Move the disconnected UPS battery connectors at the top of the battery compartment out of the way.
- Page 18 CAUTION: The cabinet is heavy (46 kg/101 lb) with the batteries removed. Lifting the cabinet from the shipping carton requires a minimum of two people. With one person on each side, carefully lift the cabinet out of the styrofoam using the handles on the cardboard (see Figure 9).
