2General Description
2.1 Reliability and Quality Standards
Congratulations on your purchase of the MINIpowerPLUS UPS.
The MINIpowerPLUS UPS incorporates the latest technological advances in power engineering to offer a
highly reliable, upgradeable UPS system with excellent electrical performance and low running costs.
Uninterruptible Power Supplies Ltd. are leading specialists in the provision, installation and maintenance of
UPS systems; and this compact and powerful UPS is just one example of our wide range of state-of-the-art
power protection devices able to provide your critical equipment with a reliable power supply for many years.
The criteria and methods used in the design, manufacture and maintenance of this UPS system are certified
to International Standard ISO 9001/EN 29001 and ISO 14001.
A full equipment specification is provided in Chapter 8 of this manual.
2.2 MINIpowerPLUS Model Range
The MINIpowerPLUS system is available in two model ranges.
MINIpowerPLUS 5000
The MINIpowerPLUS 5000 is available in both Rack-
mounted and Tower versions and uses up to four
1250VA power modules to offer a system output rating
of 1250VA, 2500VA, 3750VA or 5000VA.
Each power module requires three batteries which are
housed within the UPS cabinet to provide a completely
self-contained UPS system.
An optional external battery cabinet can be connected
to the UPS to extend the system’s autonomy time if
required.
MINIpowerPLUS 10000
MINIpowerPLUS 10000 uses between four and eight
1250VA power modules to offer a system output of
5000VA, 6250VA, 7500VA, 8750VA or 10000VA.
In this model range the batteries are contained in a
separate battery cabinet which is similar in design and
appearance to the UPS cabinet and is usually
positioned adjacent to the UPS cabinet to form a
matching suite.
If required, additional battery cabinets can be
connected to the existing battery cabinet to extend the
system’s autonomy time.

Figure 2.3 MINIpowerPLUS Power module usage
If a system is purchased without the maximum number of power modules fitted, additional modules may be
fitted in the field (up to the limit of 4/8 modules) to expand the system up to full capacity; however this
requires the UPS to be shut down while the additional module(s) and batteries are fitted.
2.3 Operating Principles
The UPS has three main operating modes:
• Mains operation
• Battery operation
• Bypass operation
Mains operation
When the mains supply is present, the input voltage is filtered then rectified by the power factor correction
stage. This optimises the use of the mains supply by making the power factor practically unity, and
compensates for any input voltage fluctuations. The rectified output from the power factor correction stage is
connected to the inverter where it is converted to a clean, sinusoidal output voltage with very low distortion.
The operation of the power factor correction stage is particularly important when operating with very low
loads. For example, with a nominal load of around 50% it is possible to sustain the inverter operation with the
input mains voltage as low as about 100V without reverting to battery power. This feature enables a more
intelligent management of the switchover to battery power and minimises battery use. During mains
operation the battery is continuously charged by a dedicated battery charger circuit.

2: General Description
Figure 2.4 MINIpowerPLUS block diagram
A rapid, synchronised by-pass circuit is used to assist during overloads that exceed the inverter’s capacity –
for example when certain peripherals that require a high start current are initially switched on.
The UPS power circuitry is a ‘passing neutral’ type: i.e. the mains supply neutral is common through to the
inverter output. During normal operation, a sensor monitors the potential between the neutral wire and the
earth wire and if it becomes excessive it:
• activates the input protection circuitry, which turns off the power factor correction stage
• switches the UPS to battery operation
• signals an error on the UPS control panel
Note: If preferred, the control software can be configured so that only an error signal is produced, without a
switchover to battery operation.
All the UPS operating functions are supervised in real-time by a microprocessor which controls and stores
certain operating parameters in addition to managing an RS232 computer interface.
Battery operation
If the mains voltage fails, or is subject to excessive sag, the voltage booster stage activates automatically to
provide an additional (or alternative) d.c. supply to the inverter. When this occurs the inverter input power
source transfers seamlessly between the power factor correction stage and the voltage booster, and the
inverter maintains the load supply without any power interruption.

The voltage booster stage obtains its power from the batteries, and when the UPS operates in this mode the
operator is informed that the battery is ‘on load’ and therefore discharging, and a number of alarms activate at
preset voltage levels as the battery discharges. The operating threshold and function of these battery alarms
can be set by the operator through the UPS Setup menu to suit local application requirements.
Bypass operation
When operating in the bypass mode the bypass circuit totally excludes the UPS and connects the UPS input
supply directly to the UPS output.
The UPS automatically switches to bypass operation if:
• the UPS develops a fault which renders it unable to sustain the UPS output supply
• the UPS is shutdown for maintenance or repair purposes
• (momentarily) to assist the UPS handle an overload condition that exceeds the inverter rating
During normal operation the inverter is synchronised to the incoming mains supply so that when a transfer to
the bypass mode is required it takes place in a synchronised manner to prevent the risk of a power break or
excessive voltage.
A dedicated bypass configuration menu provides a means of customising the by-pass circuit operation to
meet specific application demands. This feature provides many options such as: ‘automatic’, ‘disabled’, ‘by-
pass in load waiting’ mode, etc.
2.4 Warranty
The MINIpowerPLUS is supplied with a limited warranty that the UPS and its component parts are free from
material and manufacturing defects for a period of one year from the date of original commissioning or fifteen
months from the date of original delivery, whichever is the sooner. This warranty is the only warranty given
and no other warranty, express or implied, is provided.
This warranty will be invalidated if the UPS is put into use without having first been commissioned by a fully
trained and authorised engineer, unless the UPS is supplied with the batteries already fitted and connected.
This warranty does not apply to any losses or damages caused by misuse, abuse, negligence, neglect,
unauthorised repair or modification, incorrect installation, inappropriate environment, accident, act of God or
inappropriate application.
If the UPS fails to conform to the above within the warranty period then Uninterruptible Power Supplies Ltd..
will, at its sole option, repair or replace the UPS. All repaired or replaced parts will remain the property of

3Installation
3.1 Introduction
This chapter contains all the information necessary to enable you to correctly install the MINIpowerPLUS
UPS, including unpacking, storage, positioning and cabling instructions.
Commissioning options
If the UPS is delivered with the batteries already fitted and connected, the system can be considered as
being ‘plug and play’ and can be installed and powered ON by the user. However, if it is delivered without the
batteries fitted, the cabinet(s) can be installed by the user but the batteries must be fitted and commissioned
by an Uninterruptible Power Supplies Ltd. approved engineer.
Note: The MINIpowerPLUS 5000 rack-mounted UPS is always shipped with the batteries fitted and
connected.
3.1.1 Receipt of the UPS
The UPS equipment, which includes the UPS Cabinet, batteries and accessories, are delivered on pallets
that can be moved easily with the aid of a pallet jack. Before you accept receipt of the equipment ensure that
the shipment is complete and the package(s) match the description shown on the delivery note.
The UPS Cabinet is packed in a container designed to protect it from mechanical and environmental damage
during transit. This protection is enhanced by wrapping and sealing the container in a polythene sheet.
Upon delivery you should carefully examine the packing containers for signs of physical damage. If there are
signs of transportation damage you must inform both the carrier and Uninterruptible Power Supplies Ltd.
immediately.
WARNING: The electrical installation of this UPS system and its peripheral equipment must be
carried out by an authorised electrician or other suitably qualified personnel.
Uninterruptible Power Supplies Ltd. will take no responsibility for any personal injury or material
damage caused by incorrect handling, cabling, operation, or other activities that are not carried out
fully in accordance with the instructions contained in this manual.
WARNING: If the UPS is purchased and supplied without batteries, Uninterruptible Power
Supplies Ltd. will not accept responsibility for any UPS damage or malfunction caused by the
incorrect supply, storage, installation or connection of batteries by third parties.
CAUTION: When off loading the UPS equipment always keep it in an upright position.
Do not drop the equipment or stack the pallets.
Key Point: Claims for shipping damage that is discovered later when unpacking the equipment
must be filed immediately when found. All damage claims must be reported to the carrier within
seven days of receipt of the equipment.
If any shipping damage is discovered you should store all affected packaging materials for further
investigation.
WARNING: Do not attempt to install or power-up damaged equipment.

3-2 UPS453-01-00 MINIpowerPLUS User Manual Dated 08-03-12
3.1.2 Site transportation
When locally transporting the UPS equipment after it has been off loaded please observe the following
cautions:
3.1.3 Unpacking the UPS
Note: Do not unpack the equipment if you intend to put it into storage prior to use (See paragraph 3.1.5).
Castors are fitted to the UPS Tower cabinet to enable it to be wheeled into position once it is unpacked.
Before you remove a UPS Tower cabinet from its shipping pallet you should ensure that the floor surface is
level and suitable for wheeling the cabinet into its final position. You should also ensure that the floor material
can safely support the weight of the UPS equipment and batteries.
1. Remove any external polythene sheeting.
2. Remove the cardboard packing container:
Carefully cut through the securing bands then pull the container upwards.
3. Remove the protective polythene covering and any other packing from around the UPS cabinet.
4. Remove the fixings screws that secure the UPS feet to the pallet base, then carefully remove the UPS
from the pallet.
5. Retain the packaging materials for future shipment of the UPS.
6. Examine the UPS for signs of damage and notify your carrier or supplier immediately if any damage is
apparent.
3.1.4 Batteries
The UPS uses sealed, maintenance-free batteries mounted on shelves within the UPS cabinet or housed in
an external battery cabinet. Normally, the system is shipped with the batteries already installed and
connected. If the batteries are ordered and shipped separately they must be fitted by a manufacturer-
approved engineer as part of the system commissioning procedure.
3.1.5 Storage
UPS Cabinet storage
If you plan to store the UPS cabinet prior to installation it should be kept in a clean, dry environment with an
ambient temperature between +5°C to +40°C and relative humidity of less than 90%.
Ideally the UPS cabinet should be stored in its original shipping packaging, but if it is removed from its
packing container you must take measures to ensure it is protected from dust and humidity.
Battery storage
If shipped separately, the batteries should be stored in a dry, clean, cool environment and preferably in their
original packaging. If the packaging is removed, the batteries must be protected from dust and humidity.
When stored, all batteries will self-discharge at a rate that is greatly affected by the ambient temperature.
Batteries should therefore be fully charged before being put into storage and if they are to be stored for a long
CAUTION: If dropped, the weight of the UPS cabinet could cause serious injury to personnel or
damage equipment in the surrounding area. Always handle with care.
If the equipment is accidentally dropped do not connect it to the mains electricity supply.
Key Point: Before proceeding further with the installation process, check that the technical
specifications on the nameplate located on the UPS back panel matches the purchased material
detailed in the goods delivery note.
Key Point: If the batteries are shipped separately, where possible it is preferable to leave them in
their packaging until they are required for commissioning (see below for storage information).

UPS453-01-00 MINIpowerPLUS User Manual Dated 08-03-12 3-3
3: Installation
period they should be recharged periodically to prevent them from losing their original capacity. As a guide,
the batteries should not be stored for longer than the periods shown below without being recharged:
• 6 months at 20°C
• 3 months at 30°C
• 2 months at 35°C
3.2 Planning the Installation
A certain amount of pre-planning will help ensure smooth, trouble-free installation. The following guidelines
should be considered when planning a suitable UPS location and environment.
3.2.1 MINIpowerPLUS Tower versions
Cabinet positioning and accessibility
The MINIpowerPLUS 5000/10000 UPS Tower
cabinet is compact and mounted on wheeled
castors so that it can be easily moved to its
intended operating location.
As shown in Figure 3.1 the UPS and battery
cabinets require a minimum of 200 mm
clearance at the rear and either side to permit
adequate cooling airflow. However, in each case
full rear access is required for cabling, and side
access is necessary for maintenance and repair.
For this reason it is recommended that the
cabinets are located so that they can be
wheeled forward to provide the necessary side
and rear access when required.
This recommendation must be taken into
consideration when cabling the equipment so
that a sufficient cable length is provided to allow
for the prescribed cabinet movement.
Figure 3.1 shows a space of 900 mm provided at
the front of the cabinets. This allows adequate
room for the safe passage of personnel during
normal operation and also sufficient space for
the cabinets to be pulled forward for access, as
described above.
Note: Ensure that the cabinet is located in an
area where the ventilation grills are unlikely to be
accidentally covered.
Moving the UPS to is final location
• The flooring material where the UPS is to be located should be non-flammable and capable of safely
supporting the weight of the UPS cabinet and battery cabinet (where used).
• The transit route must allow the equipment to be transported in an upright position.
CAUTION: Sealed batteries must never be stored in a discharged or partially discharged state. The
batteries can be destroyed by extreme temperature, under-charge, overcharge or over-discharge!

3.2.2 MINIpowerPLUS Rack-mounted versions
Rack positioning and accessibility
The MINIpowerPLUS Rack-mounted UPS cabinet
is designed to fit into a standard 19 inch rack and
is 6U high. The cabinet is fitted through the front
of the rack, supported on suitable rails and
secured in position by means of two screws on
each side of the front of the assembly.
All MINIpowerPLUS 5000 Rack-mounted UPS
cabinets also contain the UPS batteries; however
a matching rack-mounted battery cabinet is
available if an extended battery facility is required.
Where used, the separate battery cabinet (also
6U) and UPS cabinet should preferably be fitted in
the same rack and positioned immediately
adjacent to each other.
Due to the weight of the assembly it is usual to
mount the UPS cabinet and optional battery
cabinet (where used) near the bottom of the rack.
There is no minimum space requirement above or
below the UPS cabinet when it is in-situ, but a
minimum of 200mm should be provided at the
rear of the unit to allow for adequate cooling air
flow and facilitate cabling. As the UPS cabinet is
600mm deep this implies a minimum rack depth of
800mm.
As mentioned above, rear access is required for
cabling therefore sufficient room should be
provided behind the rack to permit easy passage
– recommended 900mm. A similar space is
required at the front of the rack to enable the UPS
cabinet to be handled while it is being installed.
3.2.3 Environmental considerations
The following conditions apply to both Tower and Rack-mounted installations.
• The UPS location should be subject to a humidity of less than 90% (non-condensing) and temperature
between +15°C to +25°C. An ambient temperature of 20°C is recommended for optimum battery life.
• The location should be free from dust or corrosive/explosive gases.
• The location should not be subject to vibration.
• The air conditioning system must be able to provide a sufficient amount of cooling air to keep the room
at, or below, the maximum permissible operating temperature.
CAUTION: The UPS cabinet is heavy.
Ensure that sufficient personnel and
appropriate handling equipment are
available to install the unit safely.
