2. Installation and Operating Instruction
2.1 Unpacking & Inspection
Examine the packing carton for damage upon receipt. Once the UPS has been removed from its shipping container,
everything inside the package should be inspected for damage that may have occurred while in transit. Notify the
carrier immediately if any damage is observed. The box should include the following:
! 1 Input Power Cord ( Male "schucko" / Female IEC )
! 2 Output Power Cords (male IEC / Female IEC)
! 1 User's Manual
! 1 Telephone Communication Line Phone Jack connection cord
! 1 Remote Monitoring Software and Computer Series Interface Cable
! 1 UPS Monitoring & Automatic Shutdown Software
Retain the packing for future use or disposed of properly.

2.3 Installation
Before installation, please read and understand the following instructions:
! Placement: The UPS must be installed in a protected
environment away from heat- emitting appliances
such as a radiator or heater. Do not install this
product where excessive moisture is present.
! Ventilation: The location should provide adequate air
flow around the UPS with one inch minimum
clearance on all sides for proper ventilation.
! Charge the Battery: Your new UPS may be used immediately upon receipt. However charge loss may occur
during shipping and storage. So charging the battery for at least 8 hours is recommended to insure that the battery
is fully charged. To recharge the battery, simply leave the unit plugged into an AC outlet.
! Connect to AC: Make sure that the voltage and frequency are correct. Plug the UPS into a 2 pole, 3 wire
grounding receptacle (wall outlet). Make sure the wall outlet branch is protected. Avoid using extension cords if at
all possible. If used, make sure the extension cord is rated for 12 Amps.
! .Determining the Load:
1. Make a list of all equipment that requires protection.
2. Calculate the sum of all the V x A ratings. (Input voltage/current shown on name plate).
3. Ensure that the total VA rating does not exceed the rated capacity of the UPS. 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 / AC
input fuse blown.
! Connect the Load: Plug your primary equipment (e.g. computer, monitor, critical data storage device, etc.) into
the Backup Power outlets. Leave the power switches of the equipment in the "Off " position for the moment.
! Connect to Computer: Use the enclosed RS-232 (DB9). Plug the male end into the UPS and the female end into
an open computer COM port.
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 Fax / Modem Lines: To protect a fax or modem, connect the telephone cable from the wall outlet to
the "IN" jack of the UPS. Connect the telephone cable from the "OUT" phone outlet on the UPS to the fax or
modem. The phone jacks on the UPS accept standard sized phone cables (RJ11 communication cables).
2.4 Operation and Functional Test
! AC Mode: The UPS delivers power to the loads from the utility and maintains battery properly charged. 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.

switch on the front panel for 3 seconds or until hear a beep sound and the "AC normal" green LED

will flash every 4 seconds.
2.5 Manual Simulation of Power Outage for the UPS
To test the backup function, you may unplug the power cord of the UPS. The UPS will beep once every 4 seconds and
the LED will flash on and off.
If the UPS is left to run continuously, it is a good idea to perform a periodic function test (at least once every month) on
the unit. Observe that your equipment operates properly and uninterrupted during this period.
To conduct a simulation-test:
! Switch the UPS on and wait for the "AC normal" indicator 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 plugging the UPS power cord back into a wall outlet.
