1. INTRODUCTION
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 loa she ing occurs the UPS seamlessly shifts across to battery power keeping the
ATM operational for a certain time frame. (loa epen ent)
iii. The battery system is a 24volt system.
iv. Due to the batteries not being eep cycle batteries the software on the ATM shuts the UPS
own at 20volts. This equates to at least 90% of the power generate by the batteries.
v. Once the batteries have shut own the UPS goes into a stan by mo e. This allows the UPS
to save the remaining voltage in the batteries.
vi. Once Eskom returns the UPS automatically starts up an commences in the powering up of
the ATM.
vii. The batteries shoul thus never be allowe to ischarge completely.
1.2 Key Features
1. Compatible with both linear an non-linear loa .
2. 24 hours operation on the UPS.
3. DC start an automatic self- iagnostic function.
4. High Power 3 stage Charger
5. High efficiency esign to save electricity.
6. Low heat issipation in long time operation.
7. Design to operate un er harsh environment.
1.3 Important Notices
• Rea instructions carefully before operating Inverter.
• Inverter connection instructions must be followe .
• The unit shoul only be opene by skille personal.
• Retain the loa within in the rating of the UPSr to prevent Overloa /Short Circuit.
• Keep The UPS Clean & Dry.
2. SAFETY INSTRUCTION
2.1 Positioning
1. Do not put the Inverter on rugge or incline surface.
2. Do not install the UPS near water or in amp environments.
3. Do not block off ventilation openings in the UPS housing an on’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 an have a high short-circuit current. Please
take the precautionary measures specifie below an any other measures
necessary when working with batteries.
• Remove wristwatches, rings an other metal objects.
• Use only tools with insulate grips an han les.

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 e tended 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.

19
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 e ceeded 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 ne t 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.
