93E Uninterruptible Power Supply (UPS) System - Technical Specification and Design Documentation

This document is a comprehensive technical specification and design drawing set for an Eaton 93E 60 kVA Uninterruptible Power Supply system. The specification defines a three-phase UPS solution with dual configurations: the 93E-60 with standard internal batteries and the 93E-40 with reduced battery capacity. The 60 kVA unit operates at 208/220V AC input and output with a 129/121 amperage rating and provides maximum heat dissipation of 2.72 kW at 100% load; the 40 kVA unit operates at 208/220V with 165/181 amperage and 4.08 kW heat output. The system includes an internal battery configuration with dual-feed options and supports both single-feed jumper and bypass input arrangements. Dimensions for the primary cabinet are 74" × 23.5" × 31.5" with total weight ranging from 590 to 680 pounds depending on battery configuration.

The technical package includes detailed electrical schematics for both three-breaker and four-breaker versions with bypass capabilities, UPS module circuit diagrams showing rectifier, inverter, battery, and bypass configurations, customer wiring specifications for phase wires rated 6 AWG to 250 MCM with torque ratings of 2/0 and 250 MCM for connection terminations, and comprehensive installation and maintenance drawings. Critical inspection requirements mandate visual inspection of all connections and battery terminals, system operational testing with internal and external battery options, and functional battery testing including load bypass conditions. The specification designates responsibility for site-specific engineering requirements, integration testing, and verification of all control wiring. Unit energization checks, breaker settings verification, and electrical isolation breaker functionality testing are mandatory prior to delivery. The document establishes that Eaton retains design responsibility for the equipment, while the customer assumes responsibility for facility integration, connector compatibility, and ensuring proper grounding infrastructure suitable for the specified power requirements.
