EPS 7000 Single and Shared Systems
1.3General Description
EPS 7000 is a family of compact, high-efficiency uninterruptible power systems. Standard power ratings for single- module systems range from 300 to 500 kVA, while standard shared systems are rated up to 4000 A. EPS 7000 UPS are optimized for compatibility with non-linear computer-type loads. Computer-aided UPS diagnostics and modular construction assures that any required service on the UPS can be identified and completed rapidly. Remote system monitoring, remote annunciation of UPS performance signals, and telecommunication capabilities allow total control of the UPS by the user.
The EPS 7000 , SSC, battery, and all auxiliary equipment is listed for safety by Underwriter’s Laboratories, Inc. (UL) under UL Standard 1778 and under Canadian Standards Association (CSA) standard C22.107.
Major components of the EPS 7000 family include:
◗UPS module
◗SSC static switch cabinet
◗SSC maintenance bypass cabinet
◗UPS maintenance bypass cabinet
◗Transformer cabinet (if required)
◗Battery disconnect
Each of these cabinets is described below. Figure 1-1 shows a single-module UPS. Figure 1-2 shows a shared- system (SSC) installation. Tables 1-1, 1-2, 1-3 identify single-module 500 kVA ratings.
