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.

1.1.2 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 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

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. 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.

1.2.2 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.
