Ups Standard Features - Eaton 9355 User Manual

Introduction
Providing outstanding performance and reliability, the Eaton 9355 UPS's unique benefits including the
following:
• Online UPS design with pure sine wave output. The UPS filters and regulates incoming AC power and
provides consistent power to your equipment without draining the battery.
• More wattage in less space with a 0.9 power factor – protecting more equipment and leaving more room
for expansion.
• Support for Powerware Hot Sync
• Input current total harmonic distortion (THD) of less than five percent, using active input power factor
correction.
• ABM ®
recharge time, and provide a warning before the end of useful battery life.
• Over two hours of extended runtime with added EBCs.
• Advanced power management with the Software Suite CD for graceful shutdowns and power monitoring.
• Emergency shutdown control through the remote emergency power-off (REPO) port.
• Start-on-battery capability for powering up the UPS even if utility power is not available.
• Standard communication options with a DB-9 serial port, relay output contacts, and programmable signal
inputs.
• Optional X-Slot
control.

The control panel, located on the front of the UPS, has a four-button graphical LCD with backlight. It provides
useful information about the UPS itself, load status, events, measurements, and settings.

• Building Alarm Monitoring – Up to four 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.
• X-Slot Communication Bays – Two communication bays are standard equipment. Up to two
communication cards can be installed in the UPS at any time.

Advanced Battery Management (ABM) technology uses sophisticated sensing circuitry and a three-stage
charger. The charger is a high-frequency, IGBT-based power conversion stage that extends the useful service
life of UPS batteries by isolating the battery from the electrical environment, except for periodic charging or
reserve mode operation. ABM also protects batteries from damage due to high current charging and inverter
ripple currents. Charging at high currents can overheat and damage batteries.
ABM extends battery life by keeping the batteries charged and performing periodic battery testing. The battery
test checks the batteries by transferring to battery mode. During the test the battery voltage is constantly
monitored to determine Battery Health. ABM is intended for VRLA style batteries.
