1. Introduction
This line-interactive series is compact and pure sine wave UPS and it is
designed for essential applications and environment, such as desktops,
servers, workstations, and other networking equipments. These models are
available in the output ratings of 1000VA, 1500VA, 2000VA and 3000VA.
The series protects your sensitive electronic equipments against power
problems including power sags, spike, brownouts, line noise and blackouts.
The series is convertible to rack and tower forms. It can be placed either in
Rack 2U or Tower form. The front panel of the UPS includes LCD display
and four control buttons that allow users to monitor, configure and control
the units. On LCD, it also includes a LCD graphical bar, two status
indications and four alarm indications. A control button from the front panel
allows users to silence off the AC fail alarm and initiate the UPS self test
sequence as well. The UPS case for 1000VA ~ 3000VA is made of metal.
This series is powered from the AC mains and supply AC outputs via
receptacles on the rear panel. Communication and control of UPS is
available through serial or USB ports located on the rear panel. The serial
port will support communications directly with a server.

2. Safety Warning
DANGER:
This UPS contains high voltages. All repairs and service should be
performed by authorized service personnel only. There are no user
serviceable parts inside the UPS.
WARNING:
!This 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 this UPS in a
temperature and humidity controlled, indoor environment, free of
conductive contaminants.(Ambient :0-40°C)
!To reduce the risk of fire, connect to a circuit breaker provided with 20
amperes maximum branch circuit over-current protection.
!To comply with international standards and wiring regulations,
the sum of the leakage currents of the UPS and the connected loads
must not exceed 3.5mA.
!The socket outlet that supplies the UPS shall be installed near the
UPS and shall be easily accessible.
!Protective earthling connections shall be such that disconnection of a
protective earth should be made at one point that is the furthest away
from the UPS, maintaining the dedicated line in order to secure
equipotential connection.
!The UPS and EBMs connected in series should be installed closely
such that the operators can not touch the interconnecting wire which
is basic insulated from primary circuit.
CAUTION:
!Batteries can present a risk of electrical shock or burnt 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.

3. Installation
3.1 Inspection of Unit
Inspect the UPS upon receiving. If the UPS is apparently damaged during
the shipment, please keep the box and packing material in original form for
the carrier and notify the carrier and dealer immediately.
3.2 Unpacking the Cabinet
To unpack the system:
1. Open the outer carton and remove the accessories packaged with the
cabinet.
2. Carefully lift the cabinet out of the outer carton and set it on a flat, stable
surface.
3. Discard or recycle the packaging in a responsible manner, or store it for
future use.
3.3 UPS Setup
All model series are designed for tower and rack purpose. They can be
installed into a 19 inches equipment rack. Please follow the instruction for
Tower Setup and Rack-Mount Setup.
"Tower setup
This series of UPS can be placed horizontally and vertically. As a tower
configuration, it is provided with the optional UPS stands to stabilize the
UPS when the UPS is positioned in vertical. The UPS stand must be
attached to the bottom of the tower.

5
Use the following procedure to install UPS in UPS stands.
1. Slide down the UPS vertically and put two UPS stands at the end of the
tower.
2. Place down the UPS into two stands carefully.

6
3. Pull out the LCD box and rotate it in a clockwise direction to 90 degree
and then push it back in the front panel.
"Rack-mount setup
The series can be installed in 19 inches racks. Both the UPS and external
battery enclosure need 2U of valuable rack space.
Use the following procedure to install UPS in a rack.
1. Align the mounting ears with screw holes on the side of the UPS, and
tighten the screw.

7
2. Assemble the rack rails with the rack-mounting.
3. Slide in the UPS into the rack rail and lock it in the rack enclosure.

8
4. Tighten the screw, and the load can then be connected
3.4 EBM Installation (Optional)
"Connecting the EBM in Tower form:
1. Slide down the UPS and EBM vertically and place two UPS stands with
the extend part at the end of the tower.
2. Tighten the screw on the metal sheet for stabilization

9
3. Connect the Earth line from UPS (port A ) to EBM (port B)
4. Take off the front panel, and connect the battery terminal (A) from UPS
to EBM terminal (B) shown as below. Users need to remove the small
gate(C) on side of the front panel to allow the outlet wire of the EBM to
pass through the gate and then reassemble front panel.
