If rated unit capacities are exceeded, an overload condition may occur and
cause the UPS unit to shut down or the circuit breaker to trip.
Do not plug a laser printer or copy machine into the outlets of this UPS. The power demands of these particular
devices are much higher than typical peripherals.
! Connect the Load
Plug your primary equipment (e.g. computer, monitor, critical data storage device, etc.) into the Battery Power
Protected outlets. Leave the power switches of the equipment in the "Off " position for the moment.
! Connect to Computer
Use the enclosed RS-232 (DB9) cable. Plug the 9-pin male end into the UPS. Plug the 9-pin female end into an
open COM port on the computer (9-pin male).
! Connect Network Lines
To protect a network, connect the network cable from the network system to the "IN" jack of the UPS. Connect the
network cable from the "OUT" phone outlet on the UPS to the network station. The phone jacks on the UPS
accept standard sized network cables (RJ45 communication cables).
2.4 Operation and Functional Test
! AC Mode
The UPS delivers power to the loads derived from the utility and maintains proper battery charge. It also regulates
the output voltage within a narrow range and serves to isolate the load from surges and electrical noise brought by
the utility wiring.
! On-Battery Mode
The UPS operates on battery when the line voltage or frequency has fallen outside the limits. Local users are
alerted to this mode of operation by visual and audible indicators. The UPS provides power to the load from the
battery and through its inverter and the output voltage and frequency of the UPS are regulated within a narrow
band.
Function
Panel Indicator
Switch On
Press and hold the main on switch on the front panel for more than 3 seconds until the "AC normal"
green LED lights up. The UPS will perform a self-test every time it is switched on.
Test
Use the test function to check both the operation of the UPS and the condition of the battery.
In AC operating mode, the level indicator will show the actual load connected to this UPS normally.
Press and hold the "I" switch on the front panel for more than 3 seconds. The level indicator will
show the battery voltage for 10 seconds.
During this 10 seconds, if you press and hold the "I" switch for more than 3 seconds again, this
UPS will enter into testing mode. The battery will provide power to the load during this period.
Testing mode will check the status of battery and operation of UPS, last for 10 seconds and
transfer back to normal status automatically.
Testing mode can not be performed if the load connected is greater than 100% or the charging
voltage is lower than 52Vdc.
In battery backup mode, the level indicator shows the battery voltage level and the alarm beeps
normally. Press and hold the "I" switch on the front panel for more than 3 seconds. The level
indicator will show the load level for 10 seconds. During this 10 seconds, if you press and hold the
"I" switch for more than 3 seconds again, the alarm will be silenced. The alarm can be activated
again by repeating the same procedure show in this paragraph.
In backup mode, the UPS can be automatically turned off if none of the connected loads are
operating. (Energy saving feature)
Switch Off
Press and hold the main off switch for more than 3 seconds until the alarm goes off.
Cold Start /
This UPS can be turned on even when AC is not present.

2.5 Manual Simulation of Power Outage for the UPS
To test the backup function, you may unplug the power cord of the UPS or simply press the main on switch
(silence/test) button on the front panel. The UPS will beep once every 4 seconds and the backup mode LED will turn
on. You can press the main on switch (silence/test) again to silence the audible alarm.
If the UPS is left to run continuously, it is a good idea to perform a periodic function test on the unit (at least once a
week). To perform this test simply press the test button on the front of the UPS or unplug the power cord to the UPS to
simulate a utility blackout.
Observe that your equipment operates properly and uninterrupted during this period. Plug the power cord back in if the
function test was performed by unplugging it.

To conduct a simulation-test:
! Switch the UPS on and wait for the Power On indicator to light up. Then unplug the UPS from the AC outlet to
simulate a utility failure.
! When utility failure occurs, power is immediately supplied to your equipment from the UPS battery. The alarm will
beep once every 4 seconds, reminding you that your equipment is running on a limited power source.
! During utility failure, manually save and close the files you are currently working on. Then, switch the UPS off to
conserve the battery power for additional testing and usage.
! If the utility power is not restored, the alarm will change to rapid beeps alerting the user that the UPS will soon run
out of battery power and will shut itself down.
! Restore electrical power to connected equipment by re-plugging the UPS power cord into a wall outlet.$
Backup all unsaved files before you perform the power outage simulation test.
2.6 Operating Parameter Setting
2.6.1 Configuration Mode
Press and hold both the main on switch " I " and the main off switch "
the front panel for more than 3 seconds while the UPS is in the off status.
The UPS will now enter parameter configuration mode.
2.6.2 Display and control switch
! When the UPS enters into the configuration mode, the turn on of six
different status indicator LEDs represent different parameter being
programmed.
! Different parameter s can be selected by press and hold the main off
switch "
" for more than 3 seconds.
! Different settings can be selected by pressing and holding the main on
switch " I " for more than 3 seconds.
2.6.3 End of configuration mode
To exit the configuration mode: Press and hold both the main on switch " I "
and off switch "
" for more than 3 seconds.
2.6.4 Setting of Parameters
2.6.4.1 Output Frequency Setting
Press and hold the main on switch " I " for more than 3 seconds to turn on the right most LED. This indicates that the
UPS is configured to work at 50Hz output frequency.
Press and hold the main on switch " I " again for more than 3 seconds to configure the UPS to operate in the 60Hz
mode.
The battery backup mode output frequency will always follow the frequency of AC mains, even if the internal
presetting is different.
