1Introduction
This UPSprotects yoursensitive electronic equipment from most common power problems, including power
failures, power sags, power surges, brownouts, linenoise, high voltage spikes, frequency variations, switching
transients, and harmonic distortion.
Power outages might occurunexpectedly and power quality can be erratic. These power problems have potential
to corrupt critical data, destroy unsaved work sessions, and damage hardware — causing hours of lost
productivity and expensive repairs.
With the UPS, you can safely eliminate the effects of powerdisturbances and guard the integrity of your
equipment. Providingoutstanding performance and reliability, the UPS's unique benefits include:
Trueonline double-conversion technology with high power density, utility frequency independence, and
generator compatibility. Output power factor up to 0.9.
Three segment charging mode to increase battery service life, optimize recharge time.
Selectable High Efficiency mode of operation.
Cold start function to startup the UPS without utility.
Standard communication options: one RS-232 communication port, one USB communication port, and relay
output contacts or SNMP card.
Power Shedding function may turn off uncritical load in battery backup to make longer backup time for
critical load.
Emergencyshutdown control through the Remote Emergency Power-off (EPO) port.
The content displayed on the interface is rich. The capacity of the loads and the battery can be seen directly
and the FLASH pictures and fan rotating icon can be displayed while charging. Enhance, it is easy to know its
operation status. When UPS fails, it can show the fault code; therefore, the UPS can be repaired as soon as
possible by inquiring fault code table.
On-Line convertible LCD design: No matter what anglerequired, only pressing the key slightly to reach your
perspective needs.
For On-Line model, it is equipped with hot swappable battery feature needed for 19”rack solution.
OnLine models in a space-optimizing 2U size fitting any standard 19” rack.

2Safety Warnings
IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS
This manual contains important instructions that you should follow during installation and
maintenance of the UPS and batteries. Please read all instructions before operating the
equipment and save this manual for future reference.
DANGER
The UPS contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the
UPS.
WARNING
The UPS contains its own energy source (batteries). The UPS output may carry live
voltage even when the UPS is not connected to an AC supply.
To reduce the risk of fire or electric shock, install the UPS in a temperature and humidity
controlled, indoor environment, free of conductive contaminants. Ambient temperature
must not exceed 40°C (104°F). Do not operate near water or excessive humidity (90%
maximum).
To reduce the risk of fire, connect only to a circuit provided with branch circuit
overcurrent protection in accordance with the National Electrical Code (NEC),
ANSI/NFPA 70.
Output overcurrent protection and disconnect switch must be provided by others.
To comply with international standards and wiring regulations, the sum of the leakage
current of the UPS and the total equipment connected to the output of the UPS must not
have an earth leakage current greater than 3.5 milliamperes.
If the UPS requires any type of transportation, verify that the UPS is unplugged and
turned off and then disconnect the UPS internal battery connector.
CAUTION
Batteries can cause a risk of electrical shock or burn from high short-circuit current.
Observe proper precautions. Servicing should be performed by qualified service
personnel knowledgeable of batteries and required precautions. Keep unauthorized
personnel away from batteries.
Proper disposal of batteries is required. Refer to your local codes for disposal
requirements.
Never dispose of batteries in a fire. Batteries may explode when exposed to flame.

Rackmount Wiring Installation
This section explains:
Installing the UPS, including connecting the UPS internal batteries
Installing the UPS
NOTE Do not make unauthorized changes to the UPS; otherwise, damage may occur to your
equipment and void your warranty.
NOTE Do not connect the UPS power cord to utility until after installation is completed.
To install the UPS:
1. Remove the front cover of each UPS
Hold the cover part without LCD on the right side and extract it (see Fig.6)
FIG. 6 Extract UPS front cover

2. Connect the internal battery connector (see FIG.7)
Connect red to red, Press the connector tightly together to ensure a proper connection.
Remarks: Please note above step 1 & 2 only for replacing batteries or adding the internal
batteries.The plug will be connected properly if the UPS is with batteries installed.
CAUTION:A small amount of arcing may occur when connecting the internal batteries. This is
normal and will not harm personnel. Connect the cables quickly and firmly.

4. If you are installing power management software, connect yourcomputer to one of the
communication ports or optional connectivity card. For the communication ports, usean
appropriate cable.
5. If your rack has conductors for grounding or bonding of ungroundedmetal parts, connect the
ground cable (not supplied) to the groundbonding screw. See “Rear Covers” for the location ofthe
ground bonding screw for each model.
6. If an emergency power-off (disconnect) switch is required by localcodes, see “Remote Emergency
Power-off” (REPO) to install the REPO switch before powering on the UPS.

UPS Initial Startup
To start up the UPS:
NOTE Verify that the total equipment ratings do not exceed the UPS capacity to prevent an overload
alarm.
1. Plug the equipment to be protected into the UPS, but do not turn on the protected
equipment.
2. Make any necessary provisions for cord retention and strain relief.
3. Plug the detachable UPS power cord into the input connector on the UPS rear cover.
4. Plug the UPS power cord into a power outlet. The UPS front cover display illuminates.
5. The UPS will do self-test when power on.After that, the charger will charge the battery. If
the output displayed on LCD is “0”, there is no output. If you need the UPS output the
utility without starting the UPS when plug into the utility, you need to set bPS option to
“ON” on the setting mode, refer to Bypass function setting in “Table 6. User Settings”.
6. Press the combination start up buttons on the UPS front cover for at least half a second.
The UPS will start up and the LED will turn on and off sequentially.
7. Check the UPS front cover display for active alarms or notices. Resolve any active alarms
before continuing. See Troubleshooting “Table 23: Typical alarm conditions.” If the
indicator is on, do not proceed until all alarms are clear.Check the UPS status from the
front cover to view the active alarms. Correct the alarms and restart if necessary.
8. Verify that the indicator illuminates solid, indicating that the UPS is operating
normally and any loads are powered.
9. To change any other factory-set defaults, see “Table 6. User Settings”.
NOTE: At initial startup, the UPS sets system frequency according to input line frequency (input
frequency auto-sensing is enabled by default).
NOTE: At initial startup, please set the output voltage needed before start up the UPS, After the
subsequent startup, the UPS will output the setting voltage.
10. If you installed an optional EPO, test the EPO function: Activate the external EPO switch.
Verify the status change on the UPS display. Deactivate the external EPO switch and
restart the UPS.
NOTE: The internal batteries charge to 80% capacity in less than 5 hours. However, we
recommend that the batteries should be charged for 48 hours after installation or long-term
storage.
