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.

The Eaton 9E 20–30 kVA online power protection system is used to prevent loss of valuable electronic information, minimize equipment downtime, and minimize the adverse effect on production equipment due to unexpected power problems.

The Eaton 9E 20–30 kVA UPS continually monitors incoming electrical power and removes the surges, spikes, sags, and other irregularities that are inherent in commercial utility power. Working with a building's electrical system, the UPS system supplies clean, consistent power that sensitive electronic equipment requires for reliable operation. During brownouts, blackouts, and other power interruptions, batteries provide emergency power to safeguard operation.

The UPS is housed in a single free-standing cabinet, with safety shields behind the door for hazardous voltage protection. Figure 1-1 shows the Eaton 9E 20–30 kVA UPS.

NOTE 1 Startup may be performed by the customer’s battery qualified electrical contractor

NOTE 2 Startup and operational checks for parallel systems or installations with accessory

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 can be installed using conduit through the bottom of power terminal cover base or by routing wiring through the power terminal cover base wiring channels and must be installed in accordance with Class 1 wiring methods.

1.1.2 Control Panel

The control panel, located on the front of the UPS, contains a liquid crystal display (LCD) and pushbutton switches to control the operation of the UPS and to display the status of the UPS system. See Chapter 6, “UPS Operating Instructions,” for additional information.

1.1.3 Customer Interface

Building Alarm Monitoring – Up to three inputs in the UPS are available to connect the facility's alarm system contacts. Some system configurations may limit the number of inputs available. The UPS uses these inputs to monitor the building alarms in addition to the UPS status. See Chapter 7, “Communication,” for additional information.

Mini-Slot Communication Bays – Two communication bays are standard equipment. One to two optional Mini-Slot®connectivity cards can be installed in the UPS module at any time. Mini-Slot cards are quickly installed at the rear of the UPS and are hot-pluggable. See Chapter 7, “Communication,” for additional information.

1.1.4 High-Efficiency Normal Mode

The 9E Series UPS offers a High-Efficiency (HE) normal mode with double-conversion on demand that allows the UPS to operate in standby bypass mode. This mode allows the 9E UPS to achieve 98% efficiency while still protecting the load. High-efficiency mode is the default normal operating mode. See Chapter 6, “UPS Operating Instructions,” for additional information.

1.1.5 Battery System

The battery system provides emergency short-term backup power to safeguard operation during brownouts, blackouts, and other power interruptions. The battery system is equipped with lead-acid batteries.

The 9E–30/20 and 9E–30/30 UPS battery systems use internal batteries with External Battery Cabinet (EBC) capability. Up to two Eaton 9E External Battery Cabinets (EBCs) can be added to UPS system. The EBCs are connected in parallel with the internal batteries to provide extended run time.

The 9E–20 UPS (reduced battery sting model) battery system uses internal batteries only with no EBC capability.

All UPSs in a parallel system must have the same battery configuration.

1.1.6 Advanced Battery Management

A three-stage charging system increases battery service life by optimizing recharge time, and protects batteries from damage due to high current charging and inverter ripple currents. Charging at high currents can overheat and damage batteries.

1.2 Options and Accessories

Contact an Eaton sales representative for information about the following options.

1.2.1 External Battery Cabinet Capability

EBC capability provides the ability to add Eaton 9E EBCs to the UPS system in addition to the internal batteries. An internal UPS battery breaker and external battery terminal block are added, along with other internal parts allowing the connection of up to two EBCs.

1.2.2 External Battery Cabinet

Battery backup protection with additional runtime can be provide by equipping the UPS system with up to two External Battery Cabinets (EBCs) containing sealed lead-acid, maintenance-free batteries. The EBCs are available with two or three battery strings. Only EBC capable UPS systems can utilize EBCs. The EBCs are housed in single, free-standing cabinets designed for line-up-and-match installation, but may be installed separate from the UPS cabinet. The recommended installation location for adjacent battery cabinets is on the right side of the UPS cabinet.

1.2.3 Integrated Accessory Cabinet-Distribution

The Integrated Accessory Cabinet-Distribution (IAC-D) provides power distribution with a 42-pole distribution panel and up to three optional 3-pole 125A subfeed breakers. The IAC-D is housed in a single, free-standing cabinet designed for line-up-and-match installation, but may be installed separate from the UPS cabinet. The recommended installation location for an adjacent IAC-D is to the left of the UPS cabinet.

Introduction

1.2.4 Sidecar Integrated Accessory Cabinet-Bypass

A Sidecar Integrated Accessory Cabinet-Bypass (SIAC-B) provides maintenance bypass functions. The SIAC-B is available in a three breaker configuration enabling power to completely bypass the UPS. The UPS can then be safely serviced or replaced without interrupting power to critical systems. A four breaker configuration is available to provide a convenient method for removing power from the UPS when using the maintenance bypass to supply the load. The SIAC-B is housed in a single cabinet designed to be attached directly to the UPS cabinet. The SIAC-B can be ordered for installation on the left side or the right side of the UPS cabinet to assist in integration with the overall system.

Introduction

1.2.8 Reduced Battery String Model

The Eaton 9E–20 model is configured with four battery strings instead of six to optimize the run time for 20 kVA with a subsequent reduction in cost and weight. Reduced battery string models are non-EBC capable. If increased battery run time is required in the future, an extended run battery upgrade kit is available to increase the internal battery system to six strings.

The Eaton 9E–20 is also upgradable to full EBC capability with the addition of a 9E–20 to 9E–30/20 field upgrade kit converting the Eaton 9E–20 to a Eaton 9E–30/20 or to an Eaton 9E–30/30 with a 9E–20 to 9E–30/30 field upgrade kit.

1.2.9 kVA Upgrades

The Eaton 9E–30/20 is firmware upgradable by an authorized Eaton Customer Service Engineer to an Eaton 9E–30/30.

1.2.10 Parallel System

NOTE 1 All UPSs in a parallel system must have the same battery configuration.

NOTE 2 The SIAC-B cannot be used in a parallel system.

A parallel UPS system with up to four UPSs can be installed to provide a parallel capacity and/or redundant system. This load sharing system provides more capacity than a single UPS, and can provide backup, depending on the load and configuration. In addition, when one UPS is taken out of service for maintenance or is not operating properly, a redundant UPS continues to supply uninterrupted power to the critical load. A Controller Area Network (CAN) provides connectivity for system metering and operational mode control. The parallel system consists of two to four UPSs each with a parallel CAN, and either a IAC-T or IAC-TB to act as a tie point and to control the output.

1.2.11 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.

1.2.12 Dual Feed

Optional dual-feed input terminals are available to provide a separate bypass feed to the UPS.

1.3 Basic System Configurations

The following basic UPS system configurations are possible:

Single UPS with reduced string internal batteries

Single UPS with internal batteries and EBC capability

Single UPS with internal batteries, EBC capability, and one or two external battery cabinets

Single UPS with reduced string internal batteries and accessory cabinets

3.2.2 UPS System Power Wiring Preparation

Read and understand the following notes while planning and performing the installation:

Refer to national and local electrical codes for acceptable external wiring practices.

To allow for future kVA upgrades, consider installing a derated UPS using wiring and external overcurrent protection breakers sized for a fully rated UPS.

For external wiring, use 90°C copper wire. Wire sizes listed in Table 3-5 are for copper wiring only. If wire is run in an ambient temperature greater than 30°C, higher temperature wire and/or larger size wire may be necessary. Wire sizes are based on using the specified breakers.

Wire ampacities are chosen from Table 310-16 of the National Electrical Code® (NEC®). Specification is for copper wire with a 90°C rating.

Material and labor for external wiring requirements are to be supplied by designated personnel.

If installing an external maintenance bypass, all feeds to the UPS including the Rectifier Input Breaker (RIB) (if installed) must have a service disconnect independent of the maintenance bypass power path. Most maintenance bypass solutions provide UPS input feeds derived from but isolated from the maintenance bypass power path. If the maintenance bypass solution being installed does not provide such functionality, DO NOT use a single feeder breaker to supply both the UPS and the maintenance bypass.

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 3-5. Refer to the Eaton 9E Integrated Accessory Cabinet-Tie and Bypass Installation and Operation Manual listed in paragraph 1.7 for additional IAC-T or IAC-TB wiring and termination requirements.
