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 bottom of the cabinet with connections made to easily accessible terminals.
Control wiring is routed through the right 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 front (behind door) of the UPS and are hot-pluggable. See Chapter 7 , "Communication, " for
additional information.

1.1.4 High-Efficiency Mode

The 93E 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 93E UPS to achieve 98% efficiency while
still protecting the load. See Chapter 6, "UPS Operating Instructions, " for additional information.on setting the
UPS to work in High Efficiency mode.

1.1.5 Advanced Battery Management

A three-stage charging system increases battery service life by optimising 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.

Options and Accessories

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

1.2.1 External Battery Cabinet

Battery backup protection is provide by equipping the UPS system with up to four External Battery Cabinets
(EBCs) containing sealed lead-acid, maintenance-free batteries. 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.

1.2.2 Parallel System

A parallel UPS system with up to four UPSs can be installed to provide a parallel capacity 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) Bridge provides connectivity for system metering and operational mode control. The parallel
system consists of two to four UPSs each with a parallel CAN Bridge, and a Tie Cabinet or System Parallel
Module to act as a tie point and to control the output.
