Ups general description & installation

1. INTRODUCTION

1.1 ENVIRONMENT

1.1.1 ISO 14001 certification

The product was manufactured in a factory certified ISO 14001 respecting eco-

design rules.

1.1.2 Packing

UPS packing materials must be recycled in compliance with all applicable

regulations.

1.1.3 Lead battery

This product contains lead-acid batteries. Lead is a dangerous substance for the

environment if it is not correctly recycled by specialised companies.

1.2 SAFETY RULES

1.2.1 Safety of persons

The UPS must be installed in a room with restricted access (qualified personnel only,

according to standard EN50091-1-2).

A UPS has its own internal power source (the battery). Consequently, the power

outlets may be energised even if the UPS is disconnected from the AC-power source.

CAUTION

If primary powers isolators are installed in other area from UPS area. You must stick the following warning label on them. “ISOLATE UNINTERRUPTIBLE POWER SUPPLY (UPS) BEFORE WORKING ON

THIS CIRCUIT”

Dangerous voltage levels are present within the UPS. It should be opened

exclusively by qualified service personnel.

Warning, after the UPS shut-down, a dangerous voltage will be present on the

battery selector BCB.

The UPS must be properly earthed.

The battery supplied with the UPS contains small amounts of toxic materials.

To avoid accidents, the directives listed below must be observed.

◗

◗ Never operate the UPS if the ambient temperature and relative humidity are

◗◗

higher than the levels specified in the documentation.

Never burn the battery (risk of explosion).

◗

◗ Do not attempt to open the battery (the electrolyte is dangerous for the eyes

◗◗

and skin).

◗

◗ Comply with all applicable regulations for the disposal of the battery.

◗◗

OM226130 Rev. A 3

Page 7

Ups general description & installation

1.2.2 Product safety

A protection circuit breaker must be installed upstream and be easily accessible. Never install the UPS near liquids or in an excessively damp environment. Never let a liquid or foreign body penetrate inside the UPS. Never block the ventilation grates of the UPS. Never expose the UPS to direct sunlight or a source of heat.

1.2.3 Special precautions

◗ The UPS connection instructions contained in this manual must be followed in the

indicated order.

◗ Check that the indications on the rating plate correspond to your AC-power system

and to the actual electrical consumption of all the equipment to be connected to the UPS.

◗ If the UPS must be stored prior to installation, storage must be in a dry place. ◗ The admissible storage temperature range is -10° C to +45° C. ◗ If the UPS remains de-energised for a long period, we recommend that you

energise the UPS for a period of 24 hours, at least once every month. This charges the battery, thus avoiding possible irreversible damage.

◗ The UPS is designed for normal climatic and environmental operating conditions as

defined in the "appendices" chapter: altitude, ambient operating temperature, relative humidity and ambient transport and storage conditions.

◗ Using the UPS within the given limits guarantees its operation, but may affect the

service life of certain components, particularly that of the battery and its autonomy. The maximum storage time of the UPS is limited due to the need to recharge its integrated battery.

◗ Unusual operating conditions may justify special design or protection measures:

- harmful smoke, dust, abrasive dust,

- humidity, vapor, salt air, bad weather or dripping,

- explosive dust and gas mixture,

- extreme temperature variations,

- bad ventilation,

- conductive or radiant heat from other sources,

- strong electromagnetic fields,

- radioactive levels higher than those of the natural environment,

- fungus, insects, vermin, etc.,

- battery operating conditions.

The UPS must always be installed in compliance with:

- the requirements of HD 384.4.42 S1/A2 - Chapter 42: Protection from

thermal effects.

- standard IEC 60364-4-482 - Chapter 482: Fire protection.

The manufacturer declines all responsibility for damages to people or

equipment deriving from non-fulfilment of the above.

2. UPS GENERAL DESCRIPTION

2.1 TYPOLOGY

All UPS covered by this manual are on-line, double conversion; the inverter supplies always energy to the load, whether mains is available or not (according to the battery autonomy time).

WARNING

The UPS output is energized even during mains failure, therefore in compliance with the prescriptions of EN 50091-1, the installer will have to identify the line or the plugs supplied by the UPS making the User aware of this fact.

This configuration guarantees the best service to the User, as it supplies clean continuously regulated power and guarantees the voltage and frequency will be stabilised at nominal value independently from mains status. Thanks to the double conversion, it makes the load completely immune from micro-interruptions due to excessive mains variation, and prevents damage to the critical load (Computer Instrumentation - Scientific equipment etc.).

Picture 1 - Block diagram

OM226130 Rev. A 5

Page 9

Ups general description & installation

2.2 SYSTEM DESCRIPTION

2.2.1 Rectifier

It converts the three phase voltage of the mains into continuous DC voltage. It uses a three phase 6 pulses fully-controlled thyristors bridge. It’s designed to supply the inverter at full load and the battery at the maximum

recharge current. The system offers very low ripple content during the charging cycle.

2.2.2 12 pulses rectifier (Optional)

The 12 pulses configuration is used to reduce the distortion of the current absorbed

from the mains (THD) to a value <12%.

This ensures that the rectifier does not distort the supply mains, with regard to the

other loads; it also avoids unlikely overheating of the cables due to the harmonics circulation.

This technology uses two 6 pulse rectifier bridges, which operates with an input

voltage having a phase displacement of 30°.

This configuration allows the system to cancel the typical harmonics of the 6 pulses

rectifier, namely the 5

remain (the 11

, 13th and the multiples). This system is highly recommended for high

and 7th. As a consequence only the higher order harmonics

power equipment, where the current distortion caused by the rectifier might affect other loads connected to the mains. It’s also advisable to use 12 pulses rectification in order not to overload an emergency diesel generator supplying the system in case of mains failure.

The 12 pulse configuration can be provided with or without galvanic isolation, using

an auto-transformer or a transformer having two secondary windings displaced by 30° (delta/delta-star connection).

Picture 2 - 12 pulses rectifier without galvanic isolation

Page 10

Ups general description & installation

Picture 3 - 12 pulses rectifier with galvanic isolation

WARNING

The mechanical dimensions of UPS’s with the 12 pulses rectifier are different from those indicated at paragraph 3.3.1 and 3.3.2. These configurations are always tied to specific requirements of the purchaser, so the mechanical configuration is defined time by time.

Contact the technical office for further information.

2.2.3 Inverter

It converts the continuous voltage coming from the rectifier or from the battery into alternating voltage stabilized in amplitude and frequency.

The inverter uses IGBT technology with a frequency commutation of approximately 10 KHz.

The control electronics is completely digital and uses a 16 Bit µP, that, thanks to its processing capability, generates an excellent output sine-wave, which has a very low distortion even in presence of loads having high crest factor currents.

2.2.4 Battery and battery charger

On the PLANET E 20-30kVA and HALLEY E 20-30kVA UPS battery can be located inside the UPS for autonomy from 5 up to 15 minutes depending on the UPS power (see tables page 12); on the other hand, battery is placed on external cabinet.

Warning: only the PLANET E 20-30kVA and HALLEY E 20-30kVA UPS can have internal batteries. The UPS with bigger sizes have to be placed on external battery cabinets.

The battery charger control logic is completely integrated inside the total-controlled rectifier control board; the battery is charged, according to the DIN 41773 Standard, every time it has been partially or completely discharged and it is kept floating, even when it’s charged, to compensate for any autodischarge.

2.2.5 Static bypass

It’s designed to transfer the load between INVERTER and MAINS, and vice-versa, without break, and uses SCR’s as power commutation elements.

OM226130 Rev. A 7

Page 11

Ups general description & installation

2.2.6 Manual bypass

It‘s used to by-pass the UPS, supplying the load directly to the mains in case of

maintenance or serious failure.

WARNING

The sequence of bypass switching must be carried out with respect to the procedure

indicated on the UPS and in the chapter “Start-up, shut-down and manual bypass”. The manufacturer cannot accept responsibility for damages arising from incorrect operation.

2.2.7 Front panel

The front panel of the UPS, consisting of a double row alphanumeric displays plus 5

function keys, allows the complete monitoring of the UPS status.

The mimic diagram helps to understand the operating status of the UPS. For more information see the chapter “FRONT PANEL”.

3. INSTALLATION

3.1 RECEIPT OF THE UPS

When the UPS is received, please attend immediately to its unpacking and carry-out an accurate visual check to be sure that the equipment has not been damaged during transport.

IMPORTANT

In case of objections relating to damage incurred during transport these must be immediately notified to the transportation company after receipt of the equipment.

When the UPS is not installed immediately it must be stored carefully in vertical position, as indicated on the packing and conserved in a dry and sheltered room in its box so that it is protected from dust.

3.2 HANDLING OF THE UPS

Before positioning the UPS, in order to avoid risks of turnover, it’s recommended to move the system on the wood pallet on which the UPS is fixed.

Before the positioning in the final location, remove the UPS from the pallet.

The UPS can be lifted and handled using a pallet truck or a forklift.

The UPS can be handled only after having taken-off (manually), the lower front panel, so that a pallet truck or a forklift can be inserted (see picture 8).

3.4 ELECTRICAL CONNECTION

The electrical connection is part of the work which is normally provided by the

supplier that carries out the electrical installation and not by the UPS manufacturer. For this reason, the following recommendations are only an indication, as the UPS manufacturer is not responsible for the electrical installation.

In any case we recommend to carry-out the installation and the electrical connections

of the input and output in compliance with the local standards.

During the electrical installation take particular care to check the phase rotation with

a suitable instrument.

- UPS from 20KVA to 30 KVA

The terminals are positioned at the front of the UPS and they can be accessed by

opening the front door.

- UPS from 40KVA to 80 KVA The terminal boards are positioned at the front of the UPS, under the breakers. To

access the terminals remove the protection, extracting the fixing bolts.

WARNING

The connection to the mains must be carried out with protection fuses or circuit

breakers between the mains and the UPS.

The use of residual current devices in the line supplying the UPS is

unadvisable. The leakage current due to the RFI filters is rather high and it can cause spurious tripping of the protection device.

According to the EN50091-1 standard, in order to take into account the UPS’ leakage

current, residual current devices having adjustable threshold can be used (see tables).

3.5 BATTERY CONNECTION AND POSITIONING

IMPORTANT

For battery installation please respect the EN62040-1-2 prescriptions, paragraph

4.9.20, and at the same time all the national rules or specifications which can be applied to the premises or building.

To obtain the battery life indicated by the battery manufacturer, the operating

temperature must remain between 0 and 25 °C. However, although the battery can operate up to 40 °C, there will be a significant reduction of the battery life.

To avoid the formation of any kind of potentially explosive hydrogen and oxygen

mixture, suitable ventilation must be provided where the battery are installed (see EN62040-1-2 annex N).

For the materials installed in France, we have to apply the rules according to NFC

15-100 article 554.2: the volume of the renewed air has to be at least 0,005 NI m

per hour, where N is the number of the elements inside the battery and I is maximun current of the rectifier.

The batteries can be internal or external, however, it is recommended to install them when the UPS is capable of charging them. Please remember that, if the battery is not charged for periods over 2-3 months they can be subject to irreparable damage.

In order to avoid any damage during the transport battery is delivered with some connection cables disconnected (in order to have a battery voltage for each shelve less than 120V) and with protecteve carboard.

At the time of the installation you will have to provide to remove the protecteve carboard (as indicated on label MD388070, placed on the protecteve cardboard) and to reconnect the cables (as indicated on label MD388071, placed on the door of

the UPS).

IMPORTANT

Only the UPS’s 20KVA and 30kVA (up to 10’ autonomy) 1Ph and 3Ph, have internal batteries. The bigger sizes must be connected with external battery cabinets.

2.2 ALARMS AND OPERATING STATUS

The alphanumeric display offers a complete diagnostic of the system by showing 25

alarms and 6 operating status descriptions.

Each alarm is associated to a code that allows it to be stored in the events history.

A1 MAINS FAULT = Rectifier input mains failure

Possible causes: 1) Central system black-out (mains failure)

2) Distribution problems upstream of the UPS

3) RCB open

A2 CHARGER FAULT = Battery charger failure

A3 RECT FUSE = One or more rectifier fuses are blown

A4 THER IMAGE = Load transferred to mains due to overload. After 30’

the load is transferred back to inverter

A5 AC/DC FAULT = Rectifier output voltage out of tolerance

Possible causes: 1) Mains input voltage too high/low

2) Distribution problems upstream of the UPS

3) RCB open

4) Rectifier bridge failure

A6 INPUT WR SEQ = Input phase rotation not correct

A7 BCB OPEN = Battery circuit breaker open

A8 BATT DISCH = The battery is discharging

Possible causes: 1) Rectifier input mains failure (alarm A1 present)

2) Rectifier failure

A9 BATT AUT END = Battery autonomy (calculated) has expired

A10 BATT FAULT = Battery test failed

Possible causes: 1) The test has been carried out with the battery not

perfectly charged

2) One or more battery cells are damaged

A11 BATT IN TEST = Battery test in progress

A12 PLL FAULT = Problems with the digital synchronisation system

Possible causes: 1) Emergency mains excessively disturbed or

intermittent

2) Mains variation speed not acceptable for the UPS (for load protection reasons)

A13 INV OUT TOL = Inverter output voltage out of tolerance

Possible causes: 1) Intervention of the inverter current limitation for

excessive load (more than 200%)

2) Inverter failure

A14 OVERLOAD = Inverter overload (load exceeding 100%). The

thermal image protection is started

A15 BYP FAULT = Emergency mains not available

Possible causes: 1) Emergency mains failure

2) Distribution problems upstream of the UPS

3) SBCB open

4) Wrong input phase rotation

A16 BYP FEED LOAD = Load fed by bypass

Possible causes: 1) Inverter overload

2) Thermal image intervention

3) Forced commutation due to the bypass switch

operation

4) Inverter failure

A17 RETR BLOCK = Re-transfer between bypass and inverter blocked,

load on bypass

Possible causes: 1) Excessive repeated overloads on inverter

It is possible, after having verified that the load is correct, to reset the UPS, and

switch back the load to the inverter (see menu SPECIAL).

A18 MBYP CLOSE = Manual bypass breaker closed (the inverter is

shutdown)

A19 OCB OPEN = UPS output breaker open

A20 FANS FAILURE = Optional

A21 HIGH TEMP = High temperature on the inverter and/or rectifier

bridge

Possible causes: 1) Excessive load

2) Failure or malfunctioning of the cooling system

6 OM226131 Rev. A

Page 30

Front panel

3) Wrong positioning of the UPS (distance from walls,

altitude)

A22 BYP SWITCH = Closure of the commutation switch which forces the

load to bypass (maintenance)

A23 EPO BUS = Intervention of the emergency power off switch

according to the EN50091-1

A24 CURR STOP = Inverter bridge stop for max current

Possible causes: 1) Repeated short circuits at the UPS output

2) Inverter bridge malfunctioning

This state can be reset by means of a push-button on the µP board.

A25 SHORT CIRC = Intervention of the short circuit protection (current

exceeding 200%)

Possible causes: 1) Problems on the load

2) Distribution problems downstream of the UPS

1. INTRODUCTION

Before carrying out whatever procedure described in this chapter, read carefully the instructions, in order to avoid possible damages to persons or thing due to wrong manoeuvre.

2. START-UP PROCEDURE

For the UPS start-up, proceed as follows.

WARNING

Before switching on the UPS, make sure:

1) the emergency power off “EPO” push-button, placed near the front panel, is in the

release position; if not, press it and proceed with the start-up procedure;

2) the input and output phase rotation is correct.

NOTE

The breaker BCB is installed inside the UPS’s up to 30kVA. Batteries and the relevant breaker for UPS systems having higher power are external.

1) Close RCB and wait until display is supplied.

WARNING If you close BCB breaker before it is required (by the front panel) you can damage the inverter capacitor bank and the battery.

2) Follow the instructions shown on the display to close the circuit

breakers/isolator switches.

3) If the start-up procedure has been carried out correctly, the display will show:
