3 1. INTRODUCTI 1.1 General Description i. When the Eskom power is flowing through the UPS it keeps the voltage at a constant 220volts not allowing fluctuations in the Eskom power to affect the ATM. ii. When load shedding occurs the UPS seamlessly shifts across to battery power keeping the ATM operational for a certain time frame. (load dependent) iii. The battery system is a 24volt system. iv. Due to the batteries not being deep cycle batteries the software on the ATM shuts the UPS down at 20volts. This equates to at least 90% of the power generated by the batteries. v. Once the batteries have shut down the UPS goes into a standby mode. This allows the UPS to save the remaining voltage in the batteries. vi. Once Eskom returns the UPS automatically starts up and commences in the powering up of the ATM. vii. The batteries should thus never be allowed to discharge completely. 1.2 Key Features 1. Compatible with both linear and non-linear load hours operation on the UPS. 3. DC start and automatic self-diagnostic function. 4. High Power 3 stage Charger 5. High efficiency design to save electricity. 6. Low heat dissipation in long time operation. 7. Design to operate under harsh environment. 1.3 Important Notices Read instructions carefully before operating Inverter. Inverter connection instructions must be followed. The unit should only be opened by skilled personal. Retain the load within in the rating of the UPSr to prevent Overload/Short Circuit. Keep The UPS Clean & Dry. 2. SAFETY INSTRUCTI 2.1 Positioning 1. Do not put the Inverter on rugged or inclined surface. 2. Do not install the UPS near water or in damp environments. 3. Do not block off ventilation openings in the UPS housing and don t leave objects on top of the UPS. 4. Keep the UPS far away from heat emitting sources. 5. Do not expose it to corrosive gas. 6. Ambient temperature: 0 C - 40 C. 2.2 Maintenance and Service 1. Caution Risk of Electric Shock. 2. Batteries may cause electric shock and have a high short-circuit current. Please take the precautionary measures specified below and any other measures necessary when working with batteries. Remove wristwatches, rings and other metal objects.

Push the UP button: This will give you the options of saving the changes that have been made. Push at the correct SAVE menu. 17

19 5. FAULT TROUBLE SHOOTING 1. If the UPS is not operational after Eskom has come back on after load shedding then it could be one of three scenario s: a. The Eskom power has been off an extended period and the batteries have gone flat due to the fact that even in standby mode the UPS will still be drawing a charge from the batteries. b. The UPS is in need of a software upgrade to correct the fault c. There is a fault with the batteries. If the system is non-operational (no lights are on) once the custodian enters the cubicle the following steps need to be completed: 1) Ensure the breaker on the side of the unit is turned down. 2) Check that all the LCD display lights are off. 3) Ensure that the UPS is plugged into Eskom and the Eskom power to the UPS is off. 4) Turn the ATM off if it is still on. 5) Plug the ATM and V-Sat into Eskom and power up to ensure no fault with the ATM. 6) Power down the ATM if there is no fault. 7) Re-connect the ATM and V-Sat into the adaptor supplied which is connected to the UPS. 8) Flip the breaker on the side of the UPS into the up position. 9) The unit will turn on using the batteries. 10) The UPS LCD display should state Please wait. 11) The LCD display then states UPS Turned Off. Calibrating 12) The LCD display then states UPS Turned Off 13) Then depress the center button (green) and left button (yellow) for 3 seconds. 14) The LCD Display will then state UPS Turned On 15) Once this phase is completed the UPS should be in operational mode. 16) Power up the ATM without turning on Eskom. 17) Once the ATM is on turn the Eskom plug that is connected to the UPS on. 18) The yellow light should after 3 seconds go out and the green light should come on. This indicates that the UPS is running on mains power. After 5 minutes when both the ATM and the UPS are operational follow this procedure: 1) Switch the Eskom plug that is connected to the UPS off. 2) After 3 seconds the green light will go out and the yellow light will come on. This implicates that the UPS is running on batteries. 3) Ensure that the power supply to the ATM has not been disengaged and that it is operating normally. 4) Wait for 2 minutes then switch the Eskom plug to the UPS back on. 5) After 3 5 seconds the yellow light will go off and the green light will come back on. The unit has been tested if only briefly that it will switch from Eskom to the batteries should a power failure occur. The unit should now be fully operational. 18

20 Trouble-shooting ( Red Light will be on) 1) When the LCD Display registers a Short Circuit a number of faults could have occurred, namely: a) A greater than normal spike through the Eskom plug that shorts the fuse, b) A short on the battery terminals or bad connection, c) A possible short on the PCB cards inside the UPS due to dust, bugs, leaking water, lightning strike, d) The power output of the UPS has exceeded the 1kw limit possible in the case of the UPS being connected to 2 ATM s or e) The ATM has a built in 700 watt UPS that initializes once the ATM has been turned on. 2) When the Short Circuit occurs please follow the next instructions; a) Ensure that the UPS is switched off in accordance with the procedure as listed above. b) Once the unit is off check the fuse holder on the side of the UPS. It is easily unscrewed. Should the fuse be blown please call a technician and report the fault. If the fuse keeps blowing once changed a short circuit is materializing on the PC Boards. Please log a fault report. c) If the fuse is not blown, please check that the ATM does not have a built in UPS system. Should there be an internal UPS System pull out the sliding tray that it rests on. There is a green light on the right front of the UPS. Depress this button for 3 seconds until the internal UPS turns off. Once this has been done check the back of the UPS for 2 power cables. One is black the other should be white. One is male and the other a female connection. In order to bypass this unit please unplug them both and reconnect them together. The internal UPS is now disconnected. Please follow the re-connection procedure listed above. d) If the ATM has any liquid damage or lightning strikes please log a fault report. e) Should the UPS still remain non-operational once the power has been re-connected please log a fault report. f) Should the UPS continue to stay in Short Circuit Mode please disconnect the UPS from the Eskom mains and plug the ATM and V-Sat into Eskom. Please log a fault report. 3) Should the UPS at any time register an Internal Error please log a fault report immediately? This fault only registers once the internal software of the unit has been compromised due to the faults listed above and needs to be rectified immediately. 4) Should the unit be completely non-operational ie, all the lights are off and it seems no power is getting through the UPS to the ATM. Turn the UPS off at the Eskom socket. Re-connect ATM and V-Sat back into Eskom socket and power up. Please log a fault report immediately. This fault could be due to the batteries having run flat due to: a) A malfunction within the UPS software allowing the batteries to deplete b) A short that has compromised the charging software c) A lightning strike that has compromised the charging software or d) Faulty batteries 5) Should there be a fault with the UPS please do not disconnect Eskom from the unit or switch it off until a technician has contacted you. Please merely plug the ATM and V-Sat back into Eskom until we contact you to discuss the fault. 6) Please keep in mind that when the UPS is powering up 2 ATM s the uptime during load shedding is diminished by half. This is obviously load dependent. COMMS ERROR: 1) Loose Ribbon Cables inside the UPS. 2) Ribbon Cables need to be pushed into the seating inside the UPS Correctly. 19
