Introduction

1-4 Eaton 9E UPS (40–60 kVA, 208/220V) Generation 3 Installation and Operation Manual P-164000302—Rev 1 www.eaton.com/powerquality

1.2.8 Reduced Battery String Model

The Eaton 9E-40 model is configured with six battery strings instead of eight to optimize the run time for 40 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 eight strings.

The Eaton 9E-40 is also upgradable to full EBC capability with the addition of a 9E-40 to 9E–60/40 field upgrade

kit converting the Eaton 9E-40 to a Eaton 9E–60/40 or to an Eaton 9E–60/60 with a 9E-40 to 9E–60/60 field

upgrade kit.

1.2.9 kVA Upgrades

The Eaton 9E–60/40 is firmware upgradable by an authorized Eaton Customer Service Engineer to an Eaton

9E–60/60.

1.2.10 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

Single UPS with internal batteries, EBC capability, and accessory cabinets

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

cabinets

The UPS system configuration can be enhanced by adding optional accessories such as a Remote Emergency

Power-off (REPO) control or Mini-Slot communication cards.

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.
