Chapter 1 Introduction The Eaton® 9E 20–30 kVA uninterruptible power supply (UPS) is a true online, continuous-duty, transformerless, double-conversion, solid-state, three-phase system, providing conditioned and uninterruptible AC power to protect the customer's load from power failures.
Introduction 1.1 UPS Standard Features The UPS has many standard features that provide cost-effective and consistently reliable power protection. The descriptions in this section provide a brief overview of the UPS standard features. 1.1.1 Installation Features Power wiring can be routed to the back of the cabinet with connections made to easily accessible terminals. Control wiring is routed through the top of the cabinet and must be installed in accordance with Class 1 wiring methods. 1.1.
Introduction 1.2.3 Integrated Transformer Cabinet An single transformer Integrated Transformer Cabinet (ITC) provides three-phase 480 Vac input to three-phase 208Y/120 Vac output voltage transformation and isolation for input to the Eaton 9E UPS. An optional Dual transformer ITC adds three-phase 208 Vac input to three-phase 480Y/277 Vac output voltage transformation and isolation for output to the critical load.
Introduction 1.2.9 Monitoring and Communication Mini-Slot Cards – Optional Mini-Slot® cards support several protocols, such as SNMP, HTTP, Modbus® and RS232. See Chapter 7, “Communication,“ for additional information on monitoring and communication features. 1.2.10 Dual Feed Optional dual-feed input terminals are available to provide a separate bypass feed to the UPS. 1.2.

Chapter 2 Safety Warnings IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS This manual contains important instructions that should be followed during installation and maintenance of the UPS and batteries. Read all instructions before operating the equipment and save this manual for future reference. The UPS is designed for industrial or computer room applications, and contains safety shields behind the door and front panels.
Safety Warnings l Determine if the battery is inadvertently grounded. If it is, remove the source of the ground. Contacting any part of a grounded battery can cause a risk of electric shock. An electric shock is less likely if you disconnect the grounding connection before you work on the batteries. l Proper disposal of batteries is required. Refer to local codes for disposal requirements. l Do not dispose of batteries in a fire. Batteries may explode when exposed to flame.

UPS Installation Plan and Unpacking l l The bypass feed into this equipment uses four wires. The rectifier feed into this equipment uses four wires. The phases must be symmetrical about ground (from a Wye source) for proper equipment operation. Parallel UPS input wiring size requirements and output wiring size requirements from the UPSs to the Integrated Accessory Cabinet-Tie (IAC-T) or Integrated Accessory Cabinet-Tie and Bypass (IAC-TB) are the same as listed in Table 3-4.
UPS Installation Plan and Unpacking The power wiring terminals are pressure terminations, UL and CSA rated at 90°C. See Table 3-5 for external power cable terminations. Figure 4-7 and Figure 4-8 show the location of the UPS power cable terminals. Table 3-5.
UPS Installation Plan and Unpacking Conduit sizes were chosen from NEC Table 4, Electrical Metallic Tubing (EMT). See Table 3-6 for conduit requirements. Per NEC article 300, 3(B)(1), all three-phase conductors must be run in the same conduit. Neutral and ground must be run in the same conduit as the phase conductors. Conduit is sized to accommodate one neutral conductor the same size as the phase conductor and one ground conductor sized in accordance with NEC Table 250.122.
UPS Installation Plan and Unpacking The line-to-line unbalanced output capability of the UPS is limited only by the full load per phase current values for AC output to critical load shown in Table 3-4. The recommended line-to-line load unbalance is 50% or less. Bypass and output overcurrent protection and bypass and output disconnect switches are to be supplied by the customer. Table 3-8 lists the recommended rating for bypass and output circuit breakers. Table 3-8.
UPS Installation Plan and Unpacking LAN and telephone drops for use with Mini-Slot connectivity cards must be supplied by the customer. l The REPO feature opens all relays in the UPS cabinet and isolates power from your critical load. Local electrical codes may also require tripping upstream protective devices to the UPS. l The REPO switch must be a latching-type switch not tied to any other circuits.
UPS Installation Plan and Unpacking 2. Use a forklift or pallet jack to move the packaged cabinet to the installation site, or as close as possible, before unpacking. If possible, move the cabinets using the pallet. Insert the forklift or pallet jack forks between the supports on the bottom of the pallet (see Figure 3-3 for the UPS cabinet center of gravity measurements). CAUTION Do not tilt the UPS cabinets more than 10° from vertical or the cabinets may tip over. 3.

Section 2 Operation
Chapter 5 5.1 Understanding UPS Operation UPS System Overview The Eaton 9E UPS is a continuous-duty, solid-state, transformerless, three-phase, true online system that provides conditioned and uninterruptible AC power to the UPS system's output and critical load. The basic system consists of a rectifier, battery converter, inverter, monitoring/operation control panel, integrated communication server, and digital signal processor (DSP) logic. Figure 5-1 shows the main elements of the UPS system.
Understanding UPS Operation 5.2 Single UPS A single UPS operates independently to support an applied load from the inverter, providing conditioned and uninterruptible AC power to the critical load from the output of the module. During an outage, the inverter continues to operate, supporting power to the load from the battery supply. If the unit requires service, applied loads are transferred to the internal bypass either automatically or manually.
Understanding UPS Operation If the utility AC power is interrupted or is out of specification, the UPS automatically switches to Battery mode to support the critical load without interruption. When utility power returns, the UPS returns to Normal mode.
Understanding UPS Operation 5.2.4 Bypass Mode CAUTION The critical load is not protected from voltage or frequency fluctuations or power outages while the UPS is in Bypass mode. The UPS automatically switches to Bypass mode if it detects an overload, load fault, or internal failure. The UPS can also be transferred from Normal mode to Bypass mode manually. The bypass source supplies the commercial AC power to the load directly.
Understanding UPS Operation 5.2.5 Battery Mode The UPS automatically transfers to Battery mode if a utility power outage occurs, or if the utility power does not conform to specified parameters. In Battery mode, the battery provides emergency DC power that the inverter converts to AC power. Figure 5-4 shows the path of electrical power through the UPS system when operating in Battery mode.
Understanding UPS Operation 5.3 Single UPS Unit System Oneline Configurations The system oneline drawings in this section show the simplified internal structure of the UPS, battery supply, and basic maintenance bypass.
