3. INTRODUCTION –EP700/1000/2000/3000/6000
This On-Line-Series is an uninterruptible power supply incorporating double-converter
technology. It provides perfect protection specifically for Novell, Windows NT and
UNIX servers.
The double-converter principle eliminates all mains power disturbances. A rectifier
converts the alternating current from the socket outlet to direct current. This direct
current charges the batteries and powers the inverter. On the basis of this DC voltage,
the inverter generates a sinusoidal AC voltage, which permanently supplies the loads.
Load like computers and periphery are thus powered entirely by the mains voltage. In
the event of power failure, the maintenance-free batteries power the inverter.
This manual covers the UPS listed as follows. Please confirm whether it is the model
you intend to purchase by performing a visual inspection of the Model No. on the rear
panel of the UPS.

10.2 Input and output power cords and protective earth ground installation
1. Notes for installation
1) The UPS must be installed in a location with good ventilation, far away from
water, inflammable gas and corrosive agents.
2) Ensure the air vents on the front and rear of the UPS are not blocked. Allow at
least 0.5m of space on each side.
3) Condensation may occur if the UPS is unpacked in a very low temperature
environment. In this case it is necessary to wait until the UPS is fully dried
inside before proceeding installation and use. Otherwise there are hazards of
electric shock.
2. Installation
Installation and wiring must be performed in accordance with the local electric
code and the following instructions by professional person.
For safety, please cut off the mains power switch before installation.The battery
breaker also needs to be cut off if it is a long backup time model (“LRT” model)
or Rack model (“R” model).
1) Open the terminal block cover located on the rear panel of the UPS, please
refer to the appearance diagram.
2) It is recommended to select the UL1015 10AWG(6mm2) wire or other
insulated wire which complies with AWG Standard for the UPS input and
-１８-
output wirings.
Note: Do not use the wall receptacle as the input power source for the UPS, as its
rated current is less than the UPS’s maximum input current. Otherwise the
receptacle may be burned and destroyed.
3) Connect the input and output wires to the corresponding input and output
terminals according to the following diagram.
Note: you must make sure that the input and output wires and the input and
output terminals are connected tightly.
4) It is recommended to select the UL1015 10AWG(6mm2) green wire with
yellow ribbon for protective earth ground wire.
5) After having completed the installation, make sure the wiring is correct.
6) Please install the leak current protective breaker at the output power
distribution panel of the UPS if necessary.
7) To connect the load with the UPS, please turn off all the loads first, then
perform the connection and finally turn on the loads one by one.
8) No matter the UPS is connected to the utility power or not, the output of the
UPS may have electricity. The parts inside the unit may still have hazardous
voltage after turning off the UPS. To make the UPS have no output, power off
the UPS, and then disconnect the utility power supply.
9) Suggest charging the batteries for 8 hours before use. After connection, turn
the input breaker in the “ON” position, the UPS will charge the batteries
automatically. You can also use the UPS immediately without charging the
batteries first, but the backup time may be less than the standard value.
10) If it is necessary to connect the inductance load such as a monitor or a laser
printer to the UPS, the start-up power should be used for calculating the capacity
of the UPS, as its start-up power consumption is too big when it is started.

10.3 Operating procedure for connecting the long backup time model
UPS with the external battery
1) The nominal DC voltage of external battery pack is 240VDC. Each battery pack
consists of 20 pieces of 12V maintenance free batteries in series. To achieve
longer backup time, it is possible to connect multi-battery packs, but the
principle of “same voltage, same type” should be strictly followed.
2) The connector of the external battery cable is used to plug into the external
battery socket of the UPS, the other end of the external battery cable is used to
connect with the external battery pack(s). The procedure of installing battery
pack should be complied with strictly. Otherwise you may encounter the
hazardous of electric shock.
a) Set the battery pack breaker in “OFF” position.
b) You must connect the external battery cable to the battery first, if you
connect the cable to the UPS first, you may encounter the hazardous of
electric shock. Then connect the other end to UPS.
3) To complete the connection by plugging the connector of the external battery
cable into the external battery socket of the UPS. Do not attempt to connect
any loads to the UPS now. You should connect the input power wire to the
right position first. And then set the breaker of the battery pack in the ON
position. After that set the input breaker in the ON position. The UPS begins
to charge the battery packs at the time.

13.NOTES FOR BATTERY DISPOSAL AND BATTERY
REPLACEMENT
1) Before disposing of batteries, remove conductive object such as necklace, wrist
watches and rings.
2) If it is necessary to replace any connection cables, please purchase the original
materials from the authorized distributors or service centers, so as to avoid
overheat or spark resulting in fire due to insufficient capacity.
3) Do not dispose of batteries or battery packs in a fire, they may explode.
4) Do not open or mutilate batteries, released electrolyte is highly poisonous and
harmful to the skin and eyes.
5) Do not short the positive and negative of the battery electrode, otherwise, it may
result in electric shock or fire.
6) Make sure that there is no voltage before touching the batteries. If the battery
circuit is not isolated from the input potential circuit, there may be hazardous
voltage between the battery terminals and the ground.
7) Even though the input breaker is disconnected, the components inside the UPS are
still connected with the batteries, and there are potential hazardous voltages.
Therefore, before any maintenance and repairs work is carried out, switch off the
breaker of the battery pack or disconnect the jumper wire of connection between
the batteries.
8) Batteries contain hazardous voltage and current. Battery maintenance such as the
battery replacement must be carried out by qualified personnel. No other persons
should handle the batteries.

14. BATTERY MAINTENANCE
l This series UPS doesn’t requires much maintenance. The battery used for
standard models are value regulated sealed lead-acid maintenance free battery.
The only requirement is to charge the UPS regularly so as to maximize the
expected life of the battery. When being connected to the utility power, whether the
UPS is turned on or not, the UPS keeps charging the batteries and also offers the
protective function of overcharging and over-discharging.
l The UPS should be charged once every 4 to 6 months if it has not been used for a
long time.
l In hot regions, the battery should be charged and discharged every 2 months. The
standard charging time should be at least 12 hours.
l Under normal conditions, the battery life lasts 3 to 5 years. In case if the battery is
found not in good condition, earlier replacement should be made. Battery
replacement should be performed by qualified personnel.
l Replace batteries with the same number and same type of batteries.
l Do not replace the battery individually. All the batteries should be replaced at the
same time following the instructions of the battery supplier.
l Normally, the batteries should be charged and discharged once every 4 to 6
months. Charging should begin after the UPS shuts down automatically in the
course of discharging, the standard charging time for the standard UPS should be
at least 12 hours.

15. OPERATING MODE FOR ALL MODELS
15.1 Utility power mode
The display panel in utility power mode is
shown in the following diagram. The AC input
LED and the UPS ON LED are turned on.
The load level LEDs will be turned on in
accordance with the load capacity
connected.
1) The battery LED is turned on and the AC
INPUT LED flashes, it indicates the
voltage or frequency of the utility power
has exceeded the normal range, the UPS
operates in battery mode.
2) If output overloaded, the load level LEDs
will be turned on and alarm will keep twice
every second. You should get rid of some
unnecessary loads one by one to decrease the loads connected to the UPS less
than 90% of its nominal power capacity.
Note: Please follow the following steps to connect the generator：
l Activate the generator and wait until the operation is stable before supplying
power of the generator to the UPS (be sure that the UPS is in idle mode, no
load). Then turn on the UPS according to the start-up procedure. After the
UPS is turned on, then the loads can be connected to the UPS one by one.
l The power capacity of the AC generator should be at least twice of the UPS
capacity.
15.2 Battery mode
The display panel in battery mode is shown in the following diagram Fig.15.2. The
battery LED and the UPS ON LED are turned on. The displayed number of the
battery level LEDs will be turned on in accordance with the battery capacity. Note
that the load level LEDs in utility power mode will indicate the level of the battery
capacity in battery mode instead.
1) When the UPS is running in battery mode, the buzzer beeps once every 4
seconds. If the “ON” button on the front panel is pressed for more than 1 second
again, the buzzer will stop beeping (in silence mode). Press the “ON” button once

again for more than 1 second to resume
the alarm function.
2) When the battery capacity decreases,
the number of the battery capacity LEDs
turned on will be reduced. If the battery
voltage descends to the alarm level, the
buzzer will beep once every second to
remind the users of insufficient battery
capacity and the UPS is soon going to
shut down automatically. Then the load
operations should be carried out
promptly and the loads should be
eliminated one by one.
15.3 Bypass mode
The display panel in bypass mode is shown
in the following diagram Fig 15.3. The AC
INPUT LED and the bypass LED are turned
on. The displayed number of the load LEDs
will be turned on in accordance with the load
capacity connected. The UPS will beep once
every 2 minutes in bypass mode.
The AC INPUT LED flashes, it shows that the
voltage or frequency of the utility power has
exceeded the normal range of the UPS.
1）Other indications on the display panel are
the same in utility mode.
2）The UPS does not have the backup
function when it is in bypass mode. The
power used by the load is supplied from the utility power via internal filter.
15.4 Abnormality mode
In case the fault LED is turned on when the UPS is in use, it shows that the UPS is
