2 INTRODUCTION 2-1 Theory of operation R The main topology of the UPS consists of bypass path, AC-DC converter, DC-AC inverter, battery charger, DC-DC converter, control circuit and detection circuit. Description of block diagram PFC Control Circuit LED Board To Control Board CE N BYPASS TE Moreover, the intelligent power management software is also optional. The function and efficiency are superior to the traditional UPS.
In case the utility power fail, the AC-DC converter and charger will be off duty. The DC-DC converter works and converts the battery voltage into DC-BUS voltage. The DC-AC inverter converts the DC-BUS voltage into AC voltage. This is so called “ON-BATTERY mode”. The auxiliary power circuit supplies the designated power to all the control circuits. for the load. There is no power failure to loading equipment.
Intelligent design TE R Integrated with a microprocessor, the UPS is able to perform intelligent functions. The UPS triggers over-voltage protection function and transfers to “On- Battery mode” even when utility voltage exceeds 300V for 200V-series. In addition, the UPS can accept large voltage variation of 65V to 138V for 100V-series or 130V to 275V for 200V-series. Wide input voltage range means less battery power usage frequency and longer battery life-span.

Maybe Dangerous/Follow Instructions CE N TE PROTECTIVE GROUNDING TERMINAL: A terminal which must be connected to earth ground prior to making any other connection to the equipment. This symbol indicates the word “phase”. This symbol indicates the principal on/off switch is in the “ON” position.

3. INSTALLATION 3-1 Unpacking CE N TE R z Please read this user manual before installing the UPS. z This UPS contains batteries which are potentially hazardous to user, even when the UPS is not connected to the utility power. z Before unpacking the UPS, check the packing box. If there are any visible damage, contact your dealer at once. -This unit is to operate by any individuals with previous training. -This unit should be installed by service personnel.
(2) Plug the other end of the power cord into a two-pole, three-wire, grounding receptacle only. Avoid using extension cords and adapter plug. DO C CE N TE R { If input type is terminal type (1) Be sure to utilize UL1015#12 AWG WIRE for GES302N11XX model and UL1015#10 AWG WIRE for GES202N11XX model for power connection. (2) Connect one end of L,N,G strings to those of the terminal block and the other end to those of the switch box (L-L, N-N, G-G).
3. Charging the battery TE R { The battery charger of the UPS automatically charges the battery whenever the power cord of UPS is connected to a acceptable utility power. { When UPS is running for the first time, charge the UPS for at least 6 hours to ensure batteries inside are fully charged before operation. { You may immediately use the UPS without having to wait for the batteries to be fully charged.
{ Turn on the equipment connected to the UPS. { Caution: Do not connect a laser printer to the UPS. R { Caution: Do not connect the UPS from genertor. TE ! CE N 5. Connecting the RS-232/Dry contact { Connect the interface signal cable between the RS-232/Dry contact port on the rear panel of UPS and COM1 or COM2 of computer if necessary. The D-sub 9 connector can work as a Dry contact or RS-232 communication port depending on the type of cable and software used. Refer to section 8 for more information.

4. OPERATION 4-1 Cold start when utility is not present CE N TE R Even when there is no utility power, you can still turn on the UPS. Just press the 1/TEST button and hold for one second, the UPS will start up after you hear a “bee”. The battery LED and on-battery LED will light on and the UPS runs on “ON-BATTERY mode”. Shown as fig 4-1.
4-4 UPS self-test 4-5 Silence function CE N TE R If press the 1/TEST button when the UPS is in “ON-LINE mode”, it will make the UPS shift to “ON-BATTERY mode” and automatically perform a self-test for about 10 seconds. (Shown as fig 4-4.) The self-test function will check the condition of the battery. After self-test is finished and test is O.K, the UPS will return to “ON- LINE mode”.
CE N TE R { BATTERY REPLACE: This LED function is to alert user that the batteries should be replaced. When the microprocessor in the UPS detects a battery fault, the UPS alarm will give out three beeps. Each beep lasts for 0.5 seconds and interrupted by an interval of 0.5 seconds. After the initial 3 beeps, the alarm will continue to sound every one hour. Shown as fig 4-7. DO C Fig 4-7 Battery Replace { BATTERY LOW: This function is to inform user the remaining power capacity of the batteries.
4-7 UPS internal fault If the following conditions occur, the UPS fails. At this time the UPS will transfer to “BYPASS mode”. The bypass LED and fault LED will light on and alarm continuously. TE R If utility is too low or too high the UPS output will be disabled. For fault messages, please refer to the troubleshooting (section7) of this manual. { When the UPS inner component overheat, the UPS will protect itself by thermo-switches. This status is so-called “O.T.
5. MAINTENANCE z Normally, the life of battery is 3 years. But extreme operating condition and R environment may shorten its life-span. z To replace batteries, contact qualified personnel. z When UPS has been unused for a period of time, the batteries will discharge CE N TE slightly. It is recommended to charge the UPS once every 3 months. z Use a vacuum cleaner to get rid of any dust that may rest on the opening of the fan. z Unplug the UPS when it is not used for a long time.
