3.3 Batteries
3.4 Storage
The standard batteries for the UPS are sealed, maintenance free, internally
mounted and will typically be connected when the UPS is commissioned.
The battery life depends very much on the ambient temperature. A
temperature range between +18° and +23°C will achieve the optimum
battery life.
If the UPS is delivered without batteries, Uninterruptible Power Supplies
Ltd. is not responsible for any damage or malfunctioning caused to the UPS
by the incorrect installation or connection of batteries by third parties.
3.4.1 UPS
If you plan to store the UPS prior to use, store it unpacked in a clean dry
environment with a temperature between -20°C to +50°C and humidity of
less than 90%.
If the packing container is removed, protect the UPS from dust.
3.4.2 Battery
The UPS is equipped with sealed, maintenance-free batteries, whose
storage capability depends on ambient temperature. It is therefore
important not to store the UPS longer than 6 months at 20°C, 3 months at
30°C and 2 months at 35°C storage temperature without a battery recharge.
For longer term storage make sure that the battery is fully recharged every
6 months.
SEALED BATTERIES MUST NEVER BE STORED IN A DISCHARGED
OR PARTIALLY DISCHARGED STATE.
EXTREME TEMPERATURE, UNDER- AND OVERCHARGE AND
OVERDISCHARGE WILL DESTROY BATTERIES!
Before and after storing, charge the battery.
Always store the batteries in a dry, clean, cool environment in their original
packaging.
If the packaging is removed protect the batteries from dust and humidity.

4.1 Commissioning
Operation
The MINIpower PLUS UPS is a high quality electronic machine that must
be commissioned by a fully trained and authorised Uninterruptible Power
Supplies Ltd. field service engineer before being put into use.
The commissioning of the UPS involves the connection of the UPS and
battery, the checking of the electrical installation and operating
environment of the UPS, the controlled start-up and testing of the UPS and
customer training.
ANY MINIpower PLUS SYSTEM NOT COMMISSIONED BY AN
UNINTERRUPTIBLE POWER SUPPLIES LTD. FIELD SERVICE
ENGINEER MUST BE CONSIDERED AN ELECTRICAL HAZARD AND
UNINTERRUPTIBLE POWER SUPPLIES LTD. ACCEPTS NO
RESPONSIBILITY FOR ITS SAFE OPERATION OR THE SAFETY OF
ANY PERSONNEL. ADDITIONALLY, THE MANUFACTURER'S
WARRANTY IS IMMEDIATELY INV ALIDA TED IF THE UPS IS PUT INT O
USE BEFORE IT HAS BEEN CORRECTLY COMMISSIONED.
4.2 Operation
Figure 4.1: Block diagram
UPS313-01-00 MINIpower PLUS (Rack) User Manual, Dated 01-08-06 4-1
4.3 Operating Principles
When the mains supply is present, the input voltage is filtered and rectified
by a special input stage (power factor corrector) which optimises the use of
the mains supply , so that the power factor becomes practically unitary , and
compensates for any voltage fluctuations. This stage supplies the inverter
even in conditions of very low mains voltage.
This feature is particularly important with very low loads: with a load of
around 50% nominal load, mains operation is possible as low as about
100V without reverting to battery power. This enables more “intelligent”
management of the switchover to battery power, minimising use of the
batteries.
The mains voltage is rectified and then supplied to a high frequency
inverter to produce the ‘clean’ sinusoidal output voltage, with very low
distortion. A rapid, synchronised by-pass circuit assists during overloads
above the inverter’s capacity , for example when certain, high start current,
peripherals are switched on.
Should the mains voltage fail or be subject to excessive sag, a booster stage
is automatically activated.This employs the batteries and safeguards the
supply of power to the output inverter, and thus to the load, without any
break. The circuitry is a passing neutral type, i.e. the mains supply neutral
is common through to the inverter output.
During normal operation, a sensor verifies the difference in potential
between the neutral wire and the earth wire: should this be excessive, it will
activate the input protection and switch the UPS to battery mode, signalling
the anomaly. It is, however, possible to modify the parameters of the
software so that only signalling is provided, if preferred.
All the UPS functions are supervised in “real time” by a microprocessor
that also controls and memorises certain operating parameters, in addition
to managing an RS232 UPS-computer interface.
The UPS keeps the operator informed regarding its operating status using:
• An alphanumeric display
• A status indicator
• An acoustic alarm
The combination of these signals enables rapid and intuitive understanding
of its operating status and recognition of any problems in the power supply .
4-2 UPS313-01-00 MINIpower PLUS (Rack) User Manual, Dated 01-08-06
4.4 Operating Modes
There are three main operating modes
• Mains operation
• Battery operation
• Bypass operation
4.4.1 Mains Operation
This is the normal operating condition:
• The mains supply is converted to DC by the power factor corrector
• The inverter reconstructs a sinusoidal voltage from the DC supply
• The output filter provides smoothing of the output voltage
• The batteries are continually charged
4.4.2 Battery Operation
When there is a mains power failure, the UPS automatically switches over
to battery mode.
• The voltage of the batteries is increased by the “booster” circuit
• The inverter constructs an alternating voltage from the battery DC
supply
• The output filter provides smoothing of the output voltage
4.4.3 Bypass Operation
The bypass circuit excludes the UPS and connects the input directly to the
output. The switchover takes place in a synchronised manner to ensure the
correct output voltage is always supplied, preventing the risk of a break in
power or excess voltage.
Operation of the by-pass circuit can be customised, to meet the specific
demands of the application, by means of a dedicated menu (Config. UPS,
By-pass) which provides many options (automatic, disabled, by-pass in
load waiting mode, etc.) in order.

5.1 Introduction
5.2 User Responsibilities
Maintenance
ALL THE OPERA TIONS IN THIS SECTION MUST BE PERFORMED BY
AUTHORISED ELECTRICIANS OR BY QUALIFIED INTERNAL
PERSONNEL.
TO ENSURE OPTIMUM OPERA TION OF THE MINIpower PLUS SERIES
UPS AND CONTINUOUS AND EFFICIENT PROTECTION OF THE
CONNECTED LOAD IT IS RECOMMENDED THAT THE OPERATIONAL
PARAMETERS AND CALIBRATIONS OF THE UPS AND THE
BATTERIES ARE CHECKED EVERY 6 MONTHS.
There are no user serviceable parts contained within the UPS so the
maintenance responsibilities of the user are minimal. To maximise the
useful working life and reliability of the UPS and its batteries, the
environment in which the UPS operates should be kept cool, dry, dust and
vibration free.
5.3 Routine Maintenance
The UPS is designed to receive regular preventative maintenance
inspections. These preventative maintenance inspections are essential to
ensure that both the useful working life and the reliability of the UPS are
maximised. When the UPS is commissioned, the commissioning field
service engineer will attach a service record book to the front of the UPS
and this will be used to record the full service history of the UPS.
Preventative maintenance inspections involve working inside the UPS
which contains hazardous AC and DC voltages. Only Uninterruptible
Power Supplies Ltd. trained and authorised field service engineers are fully
aware of all of the hazardous areas within the UPS.
During a preventative maintenance inspection the field service engineer
will carry out the following checks:
• Site/environment conditions.
• Integrity of electrical installation.
• Cooling airflow.
• Rectifier operation and calibration.
• Inverter operation and calibration.
UPS313-01-00 MINIpower PLUS (Rack) User Manual, Dated 01-08-06 5-1
• Static switch operation.
• Battery status.
• Load characteristics.
• Integrity of alarm and monitoring systems.
• Operation of all installed options.
Preventative maintenance inspections form an integral part of all Extended
Warranty Agreements (maintenance contracts) offered by Uninterruptible
Power Supplies Ltd.
For further details on Extended Warranty Agreements please refer to
section 2.3.

Troubleshooting
6.1 Potential Problems and Solutions
Problem Possible Solution
When the UPS is switched on, the buzzer
sounds and the red warning light makes
alternating short-long flashes, then the UPS
switches off after 15 seconds
The UPS works but a short beep is heard every
12 seconds and the yellow warning light is lit
without flashing.
The UPS works but it beeps intermittently and
the red warning light and the yellow warning
light are flashing.
The UPS beeps continuously and the yellow
warning light flashes for about 15 seconds, after
which the UPS switches off
The UPS works but the green warning light is
flashing quickly
The connection of the neutral conductor is incorrect: swap
the connections of the neutral and phase input leads, or
exclude the neutral sensor.
Check power is present at the mains outlet.
Check that the UPS power supply cable is correctly inserted
in both the mains outlet and in the connector on the UPS
itself.
Check the fuse located at the side of the input/output
connector under the plastic housing (refer to fig.1 or 4)
There is an overload on the UPS output. Reduce the load so
that it does not exceed the maximum power that the UPS
can supply. Alternatively, if th e UPS is not in its maximum
configuration, you can ask your Service Centre to increase
the power of your UPS by fitting extra power boards and
batteries inside the UPS cabinet.
The UPS has completely flattened its batteries; it can only
start up again when the mains input line is present. Check
the magneto-thermal or differential switches that precede the
UPS and the input fuse
The mains supply is out of the limits permitted for the voltage
and/or frequency, but it can still be used by the UPS.
However, the by-pass function is not operational
The UPS beeps intermittently and the red
warning light is flashing quickly.
The thermal protection has been tripped. Switch the UPS off
and wait for a few minutes so that the internal temperature of
the UPS can get back to normal. Check that the fans operate
correctly and that the airflow is not obstructed (e.g. if the
UPS is too close to a wall). There is a fault on one of the
internal circuits. Contact your service centre.

The UPS batteries are subject to a reduction in capacity depending on their age (a
feature declared by their manufacturer in the technical manual). For example, the
reduction of capacity of a 4-year-old battery can be as much as 40%, resulting in a
proportional reduction of UPS autonomy time when running on battery power.
