Power outages can occur when you least expect them and power quality can be erratic.
7 Introduction | Providing outstanding performance and reliability, the UPS's unique benefits include: S Online UPS design with pure sine wave output. S True online double-conversion technology with high power density, utility frequency independence, and generator compatibility.
8 | Introduction Finding Information CAUTION: The Safety, Environmental, and Regulatory Information document provides important safety and regulatory information.
9 Safety Warnings | Safety Warnings CAUTION: Before performing the procedures in this document, read and follow the safety instructions and important regulatory information in your Safety, Environmental, and Regulatory Information document.
10 | Safety Warnings CAUTION: Observe the following instructions to help prevent a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage incidents: S Servicing of batteries should be performed or supervised by personnel knowledgeable about batteries and the required precautions.
11 Safety Warnings | S Do not overload the AC power supply branch circuit that provides power to the rack. S Do not stand or step on any components in the rack. WARNING: Slide/rail mounted equipment is not to be used as a shelf or work space. Do not add weight to slide/rail mounted equipment.
12 | Installation Installation This chapter explains: S Equipment inspection S Unpacking the cabinet S UPS rear panels S UPS setup and installation, including the External Battery Module (EBM) S Remot.
13 Installation | 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).
14 | Installation CAUTION: The cabinet is heavy (see page 62). Lifting the cabinets into the rack requires a minimum of two people. 2 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).
15 Installation | UPS Rear Panels This section shows the rear panels of the Dell Online Rack models. UPS Communication Bay Input Terminal Block USB Port Four IEC 320-C19 Receptacles (Load Segment 1) R.
16 | Installation UPS Front Panel This section shows the front panel of the Dell Online Rack UPS. On/Off Button LCD Panel Scroll Button (Down or Forward) Select Button Scroll Button (Up or Back) Figure 6.
17 Installation | Rackmount Setup CAUTION: The cabinet is heavy (see page 62): 1) Dell strongly recommends to remove the battery tray from the UPS before lifting.
18 | Installation Pull the battery trays out using the plastic tabs and remove the battery trays (see Figure 8). Figure 8. Removing the Battery Trays 2 If installing additional UPSs, repeat Step 1 for each cabinet. NOTE: The following instructions are the same for square-hole racks and unthreaded, round-hole racks.
19 Installation | 5 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 9). Pull the rail just past the front of the rack. Push the front end of the rail until it fully seats on the vertical rack flange and the hook latch locks in place.
20 | Installation 6 Slide the cabinet into the rack (see Figure 10). Repeat Steps 3 through 5 for any additional cabinets. Figure 10. Installing the Cabinet 7 Secure the front of the cabinet to the rack using the four thumbscrews on the mounting brackets (see Figure 11).
