RECOMENDATIONS FOR SAFE OPERATION

DO NOT FORGET!There is always risk of electrocution inside the equipment,even after disconnecting the Unit from mains,because the internal circuitry and the battery bank remain connected,thus generating Dangerous voltage levels.Therefore,don’t open the case if you aren’t qualified.
1.1 Handling,transporting and storing
The equipment must remain in its original packing,before performing any installation procedure and During the processes of transportation,storing and general handling, in order to protect it from impacts or harsh environmental conditions.
It is very important for anyone reading this to bear in mind that he UPS weights over 200 pounds or 100 kg generally (refer to the technical specifications chart for accurate weight).For this reason,the UPS must be handled only using the proper cranes or equipment intended for handling of heavy-weight loads.
It is strongly recommended that the UPS must be held the whole time in vertical position.
As soon as the UPS is received,the packing and its sealing should be checked.It has to be in good shape, this is:without any abrasion,without any damage in the sealing and free from excessive moisture. If there Is found any anomaly please notify both our customer service and the carrier company.
During storing the UPS must be held in a location protected from sun light or close to any other heat Source(as boilers, stoves, furnaces,etc).
During storing the UPS must be held in a location away from water pipes or leaks and protected from wetness or moisture.
The height over sea level may affect the performance of the equipment.
If the UPS needs to be stored more than three months,it is mandatory to provide the batteries with a Maintenance charge,in order to avoid irreparable damages and the offered warranty term.

1.2. Minimum conditions for UPS location
The location where the UPS will be finally installed should have the following minimum conditions:

• The same conditions suggested above for storing.
• In order to ease inner ventilation,there must be held 30 centimeters or 1 foot as minimum distance between the wall and the rear section of the UPS.For maintenance purposes a suitable space should be at least 1 meter or 3 feet around the UPS.
• Environmental temperature should not exceed 25℃ around the batteries,this is the normal temperature recommended by the manufacturer.Though a superior temperature level do not stop the UPS for working,the rising of this temperature level above 30℃ could reduce the useful lifespan for the batteries even to 50% or less.
• If there is air conditioning available,by any case it should not generate condensation.
• For the UPS connection it is recommended the use of flexible cables,with a length suitable for performing maintenance procedures and for the operator to access the UPS by any side.

1.3.Battery handling
The batteries are components with a great capacity for energy storage and are able to generate dangerous voltage levels inside the UPS,even though the connection to the mains is not active,For that reason the UPS and its battery bank must be operated by qualified personnel only.
DO NOT open,unseal,burn or destroy the batteries.Their chemical components are very toxic and can cause serious injuries in skin and eyes.
DO NOT expose the batteries to hing levels of heat.They may explode.
The procedure of battery disposal should be made accordingly to the current environmental regulations.

OPERATION MODES

The Gp33 Series UPS works among the next operation modes:
Normal Operation Mode
The functional schematic for the Gp33 UPS when operating in normal mode is depicted in figure 3.1.theAC Power present in the input is converted in DC power by the rectifier. The DC voltage is then used for charging The batteries and delivering power to the inverter. The power inverter takes the DC voltage at the output of the rectifier and generates a pure sinusoidal wave useful for feeding the load.
Battery Discharging Mode
In this operation mode the energy delivered as AC power to the load from the inverter was initially provided by the battery bank as DC power,without the intervention of the rectifier. The UPS automatically enters this mode when there is no voltage at the input or there is any abnormal condition. The UPS returns automatically to normal operation when the voltage is normal again.If such abnormality persists longer than the time span for which the battery bank was assembled,the UPS will eventually stop delivering power to the load in order to avoid deep discharge over the batteries.
Nevertheless, if this last event happens,the electronic control and frontal panel will continue working as a last resource(because this kind of power consumption is too low), until the battery discharging process resches dangerous level.it is hinghly recommended to turn off the UPS and disconnect the battery bank (refer to section 6.2)to avoid their complete discharge.

Electronic Bypass
In this operation mode the load is connected to the mains through an electronic switch based on SCR’s.The UPS enters this operation mode when:there was some sort of overload at the output,there was a temperature rise and it is above the nominal value of operation or the battery bank is too much discharged.
Manual Bypass
The UPS is in manual bypass mode when the load is connected directly to the mains through a bypass circuit breaker while the UPS itself remains unenergized.Thia mode allows the user or operator to carry out maintenance tasks without actually cutting the power to the load.

Manual Shutdown
The UPS is fully turned off in the manual shutdown mode,so the inverter is turned off and the load has no power through any of the bypass cicuits.Nevertheless if the battery bank is discharged and incidentally there is AC power at the input of the UPS,the battery charger circuit will work.The communications devices and the control panel also work under this mode.

Total Shutdown
When the UPS is in this State,none of the circuits or devices inside it is working,However there is still remaining energy stored in the battery bank, even though the voltage level is that previous to complete discharge,so in this state there is still risk for handing the interior of the unit.
ECO MODE
With ECO mode the load is feed by static switch, no by inverter, for allow the maximum efficiency, this mode works automatically.
If this mode is selected by user, the UPS works in normal mode during 5 minutes (this time is selectable by user) and after this time the load will transfer to static switch. In case of input power loose the UPS will transfer to battery mode automatically.
Provide schematics for reference,Please see page 32 Figure 9.1

INSTALLATION

At this point it is highly recommended the installation to be done by a qualified electrician or trained technician,this recommendation pretend to diminish the risk of damage on the unit and the odds for an accident to happen.The recommendations ahead should be taken as a guide for a safe and successful installation;anyway any recommendation should be adjusted to local valid norms.

4.1.Unpacking
The UPS unit comes in a wooden packing as is shown in Figure 4.1.The process for removing the packing should start by removing the top cap,then the lateral covers and finally the frontal and rear covers.The UPS unit is also anchored underneath the packing’s floor to a wooden stowage as is depicted in Figure 4.2. After removing the packing,the next step is to unload the UPS unit from the stowage,For this operation do as is said next:

• Remove first the lateral covers from the UPS unit.
• The levelers should be lifted up.
• Lightly bend the UPS unit in one of its sides,right or left,to ease the removing of the anchorage in the opposite side.
• Repeat the last step for the other anchorage in the opposite side.After removing this second
• Anchorage the unit will be able to move using their own wheels.
• Set up aside from the stowage a ramp strong enough to support the unit’s weight.
• Finally, the unit can roll down the ramp.
• Once on the floor, the UPS nit can be rolled to its final location, where we can lock he universal wheels and ensue the machine is stable.

4.2.RUSH REQUIREMENTS
The Gp33 Series ups requires a three phase input 400Vac, you must have a dedicated breaker for the ups distribution panel, each line in the entry and exit must have the proper gauge to carry the current to flow through them.
The sizes of the cables at the input and output change according to capacity, as shown in the following tables.

3. Lcd: the lcd screen displays information about the operation of ups battery status,input voltages,alarms,etc.
4. Input led: indicates whether there is any abnormality at the ups input. When the input is normal,the led is green color, when there is a problem is red color.
5. Bypass led: when the ups is in electronic bypass, the two leds light up intermittently.
6. Charge led: indicates the status of the charger.
7. Battery led: indicates the battery status, if the batteries are functioning normally be green and if aproblem will be red.
8. Inverter led: indicates the status of the inverter, when the inverter is on is green, if off is red.
9. Output led: indicates whether the output voltage of the ups, or if there is any problem with the output.
10. “off”: It transfers the UPS from normal operation mode to bypass mode(Pressing it for about 3 seconds) and from bypass mode to total shutdown mode (Pressing the button for more than 6 seconds).

The following table gives a more detailed description of the meaning of the leds on the mimic.
Table 5.1. Meaning of the leds.

The UPS is operating normally.
Input=green; charger =green; Batteries=flashing yellow-orange Inverter=green; output= green.| The ups operates normally, but the batteries are charging. if a power failure the ups entry will have no autonomy. Because the batteries are not charged to 100%.
Input= green; charge= red. Batteries=red. Inverter=green; output=green.| The batteries are completely discharged, in case of a court, there is no energy input to the output load. however, the batteries are charging.
Input=red; charger = red, batteries = green; inverter=green; output = green.| There was an abnormal event at the entrance of ups and the load is being fed through the inverter, the energy stored in batteries.
---|---
Input=red; charger = red;batteries = flashing red-green; inverter=green; output = green.| No energy input and energy in the batteries are running low, it also generates an audible alarm, the display will show “low battery alert”. It is advised to turn off all computers that are connected to ups.
input = flashing red-green.| The network is not optimal to switch to manual bypass.
Input= yellow.| No synchronization; the network conditions are close to be appropriate but are not required.
Input= red.| The entry conditions are not suitable to enter bypass so this operation is not allowed because it could raise problems with the load.
output= red.| The load is not being fed by the ups, consult service.
output=flashing  red-green.| The load is being supplied by the bypass, and the input conditions are not good.
output =green.| The load is being fed by the ups through the inverter or bypass still appropriate input conditions.
bypass leds, lighting intermittently.| The electronic bypass is activated.

5.2 lights frontal cover
The ups has lights on the front that displays the status of UPS as follows:

• If the lights are blues means that the load is being fed through either the inverter or bypass.
• If the lights are reds means that the load is being fed to the energy stored in batteries.
• If the lights are flashing red and blue is because the charger is not working properly, the cause may be who missed one or two phases o the entrance.
• When the charger starts and if there is no problem, the lights are flashing blue and violet.
• If you used the emergency shutdown of the ups, the light has a violet color.

7.3 Maintenance:
Except for minor routine maintenance that may be performed by the operator safety instructions to be used during maintenance of the UPS are nirmally made available only to service persons.

Communications:

8.1.rs232:
The rs232 port is located on the rear panel. this interface can be used for remote monitoring of the ups. It is recommended that the distance between the ups and the monitoring equipment does not exceed 10 meters.
If the computer you want to do the monitoring does not have rs232 port. We recommend using a usb to serial converter trendnet tu-s9. monitoring can be done from a pc using HyperTerminal, which is included in versions of “windows” less than or equal to “windows xp”.for newer versions you can download the software from the Internet.running the program window appears as shown in figure 8.1:

Name your connection and select an icon and click ‘OK”.then in the next window in the “connect using”select the port which is connected to the ups and click “OK” (see figure 8.2). in the next window set the port,Select 2400 bits per second transmission rate, with 8 bits of data per frame, no parity bit, a stop bit and no flow control, as shown in figure 8.3. click “OK”. then see the window shown in figure 8.4. click on the button (Disconnect) and then(properties). then see the window shown in figure 8.5. select the “settings” tab andclick on the “ascii setup”(see figure 8.6). in the next window(figure 8.7) check the “append line feeds to incoming line ends”and click”OK” until you see the window in figure 8.4. click on the buttom(call).

now you can see in figure 8.4 window that appears on the lcd screen of the ups to change the menu click on the computer keyboard key ↑or↓ these amount to “arrow” and “down arrow”, respectively, on the front panel of ups. The equivalent of the button “enter”/esc” on the computer keyboard is the ←key. Can it while connected to the serial port to display lines with strange characters, this is normal in the operation of the ups.

8.2. Network adapter(optional)
The network adapter enables the exchange of information across a lan network and/or internet.
monitoring through the network adapter can be of two types which can be used independently or simultaneously if desired:
via http server, the ups acts as a small http server, monitoring can be done from any computer that has access to the ip address assigned to the ups. the other option is for snmp, with this option, the manufacturer provides snmp adapter software (netagentutility) that allows monitoring of the ups in real time. the software provides audible signals and signs on the screen when an abnormality occurs, additionally provide the ups mib to adapt to an environment with a professional monitoring nms program such as openview.
If it is enabled, the UPS can send alert messages up to 8 different e-mail address when the there is an abnormal working condition. The addresses include cellphone numbers.

8.3. Cellular modem(Optional)
The cellular modem let you use a GSM network to monitor the UPS atate. This system allows you to know in real-time the behavior of the equipment in a remote place where a cellular network is present. With the system you can check up to 130 variables among which you can find:voltages and frequencies at the input, voltages and frequencies at the output, output currents, battery charge percentage, etc. If an alarm occurs, its description is transmitted via e-mail or SMS. The system allows remote management and control.
The data corresponding to the state of the UPS can be seen, through internet, in a web page.
