Installation

3.1 Introduction This chapter contains all the necessary information for the correct

unpacking, positioning, cabling and installation of the MINIpower PLUS

UPS.

ALL THE OPERATIONS IN THIS SECTION MUST BE PERFORMED BY

AUTHORISED ELECTRICIANS OR BY QUALIFIED PERSONNEL.

UNINTERRUPTIBLE POWER SUPPLIES LTD. WILL TAKE NO

RESPONSIBILITY FOR ANY LOSS, PERSONAL OR MATERIAL

DAMAGE CAUSED BY INCORRECT CABLING, OPERATIONS OR

ACTIVITIES WHICH ARE NOT CARRIED OUT AS PER THE

INSTRUCTIONS CONTAINED IN THIS MANUAL.

3.1.1 Receipt of the UPS

The packing container of the UPS protects it from mechanical and

environmental damage. To increase its protection the MINIpower PLUS

UPS is wrapped with a plastic sheet.

Upon receiving the UPS, carefully examine the packaging and the UPS for

any sign of physical damage.

Ensure that the received UPS corresponds to the description indicated in

the delivery note.

3.1.2 Nameplate

The technical specifications of the MINIpower PLUS UPS are provided on

the attached nameplate.

3.2 Unpacking When unpacking the UPS observe the “FRAGILE” and “ARROW”

indications on the packaging.

Perform the following steps to unpack the UPS:

• Cut the wrappers and remove the packaging by pulling it upwards.

• Remove the plastic cover from the UPS.

• Remove the UPS from the pallet.

• Retain the packaging materials for future shipment of the UPS.

• Examine the UPS for any sign of damage. Notify your supplier

immediately if damage is apparent.

3-2 UPS313-01-00 MINIpower PLUS (Rack) User Manual, Dated 01-08-06

3.3 Batteries 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 notresponsiblefor anydamage or malfunctioning causedtothe UPS

by the incorrect installation or connection of batteries by third parties.

3.4 Storage

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.

UPS313-01-00 MINIpower PLUS (Rack) User Manual, Dated 01-08-06 3-3

3.5 Positioning The MINIpower PLUS is a compact and light UPS and can easily be moved

to its final position.

The UPS should be located where:

• Humidity and temperature are within prescribed limits.

• Fire protection standards are respected.

• Cabling can be performed easily.

• Access is available for service or periodic maintenance.

• Required cooling air flow is possible.

• The site air conditioning system has sufficient capacity.

• Dust or corrosive/explosive gases are absent.

• The site is vibration free.

• Minimum 200 mm space is required above the UPS for proper

cooling.

Figure 3.4: Cabling

The UPS is fitted with protection against incorrect connections. This

is indicated by its red warning light, lit without flashing, and the

continuous sounding of its internal buzzer. Should you note this

signal immediately after switching the UPS on, switch it off and

remove the power supply plug immediately.

For 1250/2500/3750/5000 Versions

Since current dispersion towards earth of all the loads merges in the

UPS protection wire (earth wire), for safety reasons, it is essential to

check that the sum of these currents does not exceed 2.7 mA,

according to standard EN 50091-1-1.

1. Wire up the Input-Output

connector using insulated cable

(min. 2.5mm2).

2. Insert the connector into the

plastic housing and secure using

the screws supplied. Secure the

wires to the housing using the

cable grip.

3. Remove plug cover by removing

its screws.

4. Put the Input-Output connector

into the plug [9] on the rear of

the UPS, and secure to its case

using the screws supplied

(Figure 3.3).

5. Check all UPS loads are OFF and connect them to the output socket.

6. Insert the power supply plug into a power outlet adequate for the voltage and current required.

Ensure the UPS has been switched off and disconnected from the

mains supply before proceeding with connections

Figure 3.6: External Battery Cabinet Connectors

The UPS is complete with connections for additional

battery cabinets. One or more extra battery cabinets

can be fitted to a single cabinet UPS as follows:

1. Loosen screws 1 and 2, but do not unscrew

them completely.

2. Slide the protective casing so that the connectors

located inside the box are completely accessible.

3. Tighten the screws to secure the metal protection.

4. Connect the battery cabinet to the UPS using the

dedicated cables.

5. Use the plaited conductor supplied to safeguard

a good contact with earth.

Operation

4.1 Commissioning 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 INVALIDATED IF THE UPS IS PUT INTO

USE BEFORE IT HAS BEEN CORRECTLY COMMISSIONED.

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, itwill

activatethe inputprotectionand switch theUPS tobattery 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.
