2 Introduction

The product described in this manual is an Uninterruptible Power System (UPS) intended for marine applications. It is a true online, continuous duty, double conversion, static state, single- or three-phase system, providing conditioned and uninterruptible AC power to protect the customer’s load from all nine different power failures.

2.1 System description

The UPS units are used to provide back-up power for safety, propulsion and cruising related systems, protect sensitive IT equipment and prevent loss of valuable electronic information, minimise equipment downtime, and minimise the adverse effect on different equipment due to unexpected power problems.

The UPS system continually monitors incoming electrical power and removes the surges, spikes, sags, and other irregularities that are inherent in commercial utility power. Working with a vessel‘s electrical system, the UPS system supplies clean, consistent power that sensitive electronic equipment requires for reliable operation. During brownouts, blackouts, and other power interruptions, batteries provide emergency power to safeguard operation.

The UPS system is housed in single freestanding cabinets. The cabinets line up and match in style and colour, and have safety shields behind the doors for hazardous voltage protection.

2.2 Active-Front technology

Traditional input THD filters are no longer needed with this UPS product. The build-in advanced rectifier technology of UPS modules provides perfect sinusoidal input power quality at 0.99 input power factor with harmonic content less than 5% THD(i). This leads to more reliable total system operation and savings in generator and transformer sizing as losses in the windings are minimised.

Due to the active front rectifier, the UPS is comparable to a clean resistor load from the mains perspective. Thus, the high input power factor provides minimised cabling and fusing costs due to no reactive power consumption.



User's Guide

P-164000341

Revision 1

The low harmonic currents are due to high input power factor and provide the benefits:

• No additional losses in wires and cables

• No extra heating of transformers and generators with shortened service life

• No false circuit breaker tripping and malfunction

• No erratic operation of computers, telecommunication, monitors, electronic test equipment etc.

• No Resonance with power factor correction capacitors

2.3 Advanced Battery Management (ABM)

™

The ABM monitors the status of the battery and charges it only when the battery needs charging.

This is the key to long battery life with the ABM due to low generation of corrosion inside the battery.

It also monitors that the load never crashes because of bad or defected battery.

The main cause for corrosion is current flowing through battery. The more current going through battery, the shorter the battery life. Current flows through battery when it is discharged or charged.

There is very little that can be done for discharging, because it depends on number of power outages in utility line.

The ABM is very valuable feature since most of the time battery does not need any charging. The charging is controlled and initiated on the following occasions:

• When turning the unit on

• After maximum 28 days without charging

• If the open cell voltage decreases below predetermined voltage level

Hence, the function of ABM system is to prolong the battery life considerably compared to traditional system that uses float-charging technology. This means that there is no current going through batteries all the time and causing corrosion. In a traditional online UPS the inverter also causes ripplecurrent to be fed to batteries causing corrosion.

2.4 Hot Sync

®

technology

The UPS product features U.S. #5,745,365 patented paralleling technology that provides N+X redundancy without introducing a single-point-of-failure. The products utilising the Hot Sync are completely autonomous and the only thing common among them is the critical output power bus.

The Hot Sync is 100% mathematical firmware that makes it more reliable than traditional paralleling techniques. Because the solution is implemented intrinsically, and Hot Sync is always active, the UPS modules do not know whether or not they are even in parallel.

A parallel UPS system means the linking together of two or more UPS units in parallel so that in the unlikely event one fails the other can automatically take up the load. Traditionally a parallel redundancy configuration is achieved by having a random or fixed master-slave relationship among the UPS units.

This master logic gives out individual commands to all the slaves units. This master logic gives out individual commands to all the slaves units, but if the master logic or communication to slaves fails, it can lead to a single-point-of-failure for the whole system, and cause the whole UPS system to be in trouble.

P-164000341

Revision 1



User's Guide

5

The Hot Sync ® technology was developed to allow parallel capacity system and to maintain the highest system availability. An industry leading paralleling technology in its own right, the patented

Hot Sync enables you to set up a parallel redundant system giving you 100% conditioned power at all times. Its unique digital design eliminates the system level single point of failure inherent in traditional parallel UPS modules, and exponentially increases the reliability of the overall system.

Hot Sync allows up to four UPS units to cover the same load in parallel and redundant configuration.

No vulnerable master logic is needed in this patented design. It provides automatic load sharing and module level redundancy with nothing other than the power connecting the Hot Sync version of UPS modules.

2.5 DNV Type approval and ABS product design assessment

Eaton 9155 and 9355 Marine UPS units can also be ordered with RFI filters installed at the factory, making them especially suitable for use with vessel's sensitive bridge equipment. With an RFI filter, the electromagnetic compatibility (EMC) requirements are complied with according to system standard (IEC 60945). This design has Det Norske Veritas (DNV) type approval and American Bureau of Shipping (ABS) product design assessment. To save space, the filter is mounted on the top of the

UPS module.

2.6 Basic system configuration

The following basic UPS system configurations are available:

A single UPS system:

• UPS cabinet (Single-phase in/out: 8-10 kVA, three-phase in and single-phase out: 8-10-12-15 kVA, three-phase in/out: 8-10-12-15 kVA)

• Battery cabinets for extended back-up time

• Internal and/or external transformers with multiple input and output voltage choices

• Multilingual LCD display for easy configuration (Std.)

• Basic communication capability (Std.)

• Internal or external Maintenance Bypass Switch (MBS) for isolating the UPS during maintenance, without interrupting continuous power to the load.

Adding optional accessories can enhance the UPS system configuration. These include extensive Xslot communication adapters.

3 Mechanical installation

The UPS and accessories are delivered on a specifically designed pallet that is easy to move with a forklift or a pallet jack. Keep the UPS always in upright position and do not drop the equipment. Do not either stack the pallets because of high-energy batteries involved and the heavy weight.

3.1 Delivery check

The UPS is delivered with the following items:

• Plastic bag containing:

• User’s Guide, paper format, English language

• UPS Safety Manual, multilingual

• Residual voltage warning stickers

• Software Suite, CD-ROM format, English language

• RS-232 serial cable for the Software Suite

• Delivery documents

3.2 Unpacking and visual inspection

Check that there are no signs of shipping damages. The models higher than 1m are equipped with

'Tip&Tel' indicator. The indicator should be intact if the equipment has been transported in the upright position.

NOTE

A claim for shipping damage must be filed immediately and the carrier must be informed within 7 days of receipt of the equipment. The packing materials should be stored for further investigation.

Before unpacking, use a forklift or pallet jack to move the equipment as close as possible to the installation site. Unpack the equipment by removing the packing and shipping materials. Make a visual inspection and check that the inside 'Drop&Tel' indicator is intact. Make sure that the floor surface is solid and suitable for heavy weight and remove the equipment slowly from the pallet using lifting belts or other suitable method. Be sure to always lift from the bottom of the unit as the top of the cabinet is not designed to carry any weight. Discard or recycle the pallet and the other shipping materials in a responsible manner.

Check the information on the type designation label of the equipment to verify that the unit is of the correct type. The type designation label includes ratings, a CE marking, a type code, a part number and a serial number. The serial number is important when making inquiries. It allows individual recognition of the equipment.

4 Planning before installation

The equipment must be installed in upright position and it requires space both front and back side to enable cooling airflow. The cooling air enters the unit through air inlets in the front and exits from the rear of the unit. The required minimum clearance from unit rear to an obstruction is 150 mm. For service and maintenance, 500 mm of empty space above the UPS unit is also required.

It is required to arrange ventilation of the UPS room. Sufficient amount of air cooling is needed to keep the max. room temperature rise at desired level:

• Temperature rise of max. +5°C requires the airflow of 600 m³ per 1 kW of losses.

• Temperature rise of max. +10°C requires the airflow of 300 m³ per 1 kW of losses.

An ambient temperature of 15 to 25 Celsius degrees is recommended to achieve a long life of the

UPS and batteries. The cooling air entering the UPS must not exceed +45 °C. Avoid high ambient temperature, moisture and humidity.

The floor material should be non-flammable and strong enough to support the heavy load.

5 Cabinet installation

The required distance for UPS units next to each other is 10 mm, but for maintenance and service purposes, it is recommended to leave 100 mm space on both sides of the unit when possible. The same applies to the optional battery cabinets that should be installed next to the UPS cabinet.

Figure 5-1: Marine UPS unit with internal input transformer

The UPS family has several alternative battery cabinets and configurations depending on the selected back-up time and quality of batteries.

5.1 Maintenance bypass switch

UPS models with an integrated input transformer are supplied with an internal maintenance bypass switch (MBS). The MBS may also be ordered as an integrated MBS mounted on the back of the UPS, or as a separate MBS for wall mounting near the UPS. The internal MBS and the rear-mounted MBS are factory installed.

5.2 Transformer option

The galvanic isolation transformer can be ordered as factory installed. The transformer is an integral part of the UPS unit and it can be connected to the input or the output of the system. Systems with factory installed transformers are referred to as: 9155 NT-model (3 phase in, 1 phase out), 9155 STmodel (1 phase in, 1 phase out) or 9355 NT-model (3 phase in, 3 phase out). With transformers, UPS can also operate in different voltages. Transformer configurations and operation voltages can be customized to match the customer needs. Alternatively, isolation transformers can be purchased as separate items.

The over temperature sensor cable from the transformer module is connected to the control input

(X44) and the status information from the maintenance bypass switch is connected to the control input (X45). In the factory installed systems these cables are ready-made for use.

P-164000341

Revision 1

Figure 5-3: UPS unit with the factory installed isolation transformer

5.3 External battery cabinet option

It’s recommended to install external battery cabinets next to the UPS unit. The battery cabinet can be placed on either side of the UPS unit. Before the installation, check that the battery voltage values, in the type plate of the UPS and the external battery cabinets, are the same. The cables are delivered with the external battery cabinets. See Chapter 6.3 External Battery Cabinet (EBC) installation procedure on page 37.

WARNING

The UPS contains high DC voltages. A qualified person must do the connections between the

UPS and the external battery cabinet(s). The battery cabinet is connected electrically in parallel with the internal batteries of the UPS.

5.4 Battery racks

External battery racks shall be sized to take the voltage drop in the cable into account. To obtain support and help contact the local office or agent authorised by the manufacturer.

6 Electrical installation

The customer has to supply the wiring to connect the UPS to the local power source. The electrical installation procedure is described in the following text. The installation inspection and initial start up of the UPS and extra battery cabinet shall be carried out by a qualified engineer with UPS installation experience.

WARNING

Physical injury or death may follow, or damage may occur to the UPS, or the load equipment if these instructions are ignored.

The UPS unit has the following power connections:

Rectifier input:

• Three-phase (L1, L2, L3) and protective earth (PE) connection

• Single-phase (L1) and protective earth (PE) connection. Neutral (N) has isolated connection point and Neutral from the bypass input is used in the rectifier. N can work also as L2.

Bypass input:

• Three-phase (L1, L2, L3), Neutral (N) and protective earth (PE)

• Single-phase (L1), Neutral (N) and protective earth (PE) connection. N can work also as L2.

Load output:

• Three-phase (L1, L2, L3), Neutral (N) and protective earth (PE) connection

• Single-phase (L1), Neutral (N) and protective earth (PE) connection. N can work also as L2.

Battery:

• Plus (+), minus (-) and protective earth (PE) connection for the external batteries.

NOTE

The rectifier requires a Neutral (midpoint) to operate. It’s connected internally from the bypass terminal to the rectifier, see wiring diagrams later in this chapter.

NOTE

Care needs to be taken to ensure that the input supply neutral reference is not disconnected whilst the UPS is in service.

Revision 1

6.1 Power cables and protective fuses

Always use copper cable types to fit terminals with approximately 1.5 Nm torque for different load currents. The Cu cable sizing is based on multi-core cables laid in conduits/trunkings on the wall or on the floor (installation procedure C), ambient temperature 25°C, PVC insulation, surface temperature up to 70°C. Cables of several UPS can be installed in parallel to each other.

Standards SFS 6000-5-52 (2002) and IEC 60364-5-52 (2001-08) “Electrical installations of buildings” with normal 1.7 x Neutral conductor rating for IT loads are used as a sizing guide. For any other conditions, size the cables according to the local safety regulations regarding installation environment, appropriate voltage and currents of the UPS.

Fuses are sized according to local safety regulations, appropriate input voltage and the rated current of the UPS. Therefore, protect the input and bypass cables with gG (gL) fuses or B-C-D type of circuit breakers against overload and short-circuit.

Contact the manufacturer’s authorised agent or the local office for assistance at fuse and cable sizing.

Refer to the recommended cable and fuse ratings in the tables presented with the wiring diagrams.

6.2 Wiring procedure

Depending on the model the power cable terminals can be located either in the back of the UPS unit, in the front of the factory installed transformer or on top in Type Approved (TA) models. The qualified engineer is responsible for the correct electrical installation. They must be authorised by the manufacturer.

7.3 External control connections

The UPS has an input/output interface for direct communication with your computer system. It is located behind the front bezel of the UPS unit. The cables connected to these terminals should be connected to cable clips.

Input and output terminals have a functional isolation from terminal to terminal. They are connected to the chassis through individual 1 MΩ resistors.

Figure 7-3: External control cable connections to the UPS

NOTE

Pay attention to proper polarity if one is using a semiconductor switch type. A relay or other mechanical control is a preferred method.

7.3.1 Emergency Power Off (EPO)

EPO is used to shut down the UPS from a distance. This feature is intended for an emergency power down. There are two different modes of operation that can be used: normally closed (NC) contacts at

X52 and normally open (NO) contacts at X12. Pins 1 and 2 at the remote shut down terminal X52 are as factory default closed. When the contacts at X52 are opened, the UPS output will be immediately shut down and the battery breaker (F1) opened. The Emergency Power Off circuit is powered by the

UPS unit's internal auxiliary power. Do not apply power from external source to terminals X52 or X12.

NOTE

EPO does not necessarily disconnect supply to load when unit is on internal or external bypass. Guaranteed disconnection of bypass supply has to be through a separate disconnect switch located in the supplying switchgear cabinet.

In order to have the UPS running again pins 1 and 2 of connector X52 have to be reconnected and the UPS started manually. The pins must be shorted in order to keep the UPS running. Maximum resistance is 10 ohm. The EPO shall not be galvanically connected to any mains connected circuits.

Reinforced insulation to the mains is required. See also Chapter 8.5 Start-up after EPO on page

56.

If the use of normally open EPO operation is desired, the loop on X52 has to be retained and the normally open EPO switch connected to X12. Operation is as above.

7.3.2 Relay outputs

The UPS incorporates a programmable relay output with potential free contacts at X57 for remote alarm indications. It is rated for max. 30 VAC 1 A or 60 VDC 0,2 A nominal values. Additional (4) relay outputs can be obtained with the XSlot compatible AS/400 Relay Module (optional). For more information see Chapter 8.2.4 Using relay outputs on page 54.

WARNING

The relay contacts must not be directly connected to mains related circuits. Reinforced insulation to the mains is required.

7.3.3 Programmable signal inputs

The UPS incorporates two programmable inputs (X44, X45). Use of a non-polar (relay) control input is recommended. The pins must be shorted with maximum resistance of 10 ohm in order to activate the specific input.

NOTE

Please note the polarity of the inputs as indicated in the external control connections if used with a polarity control.

The default and programmable settings for the signal inputs are:

• Disable Bypass Operation (If active the automatic transfer to the static bypass is prevented.)

• Charger off (If active the batteries charging is disabled. In case of mains power outage the discharge of batteries is supported.)

• Remote ON/OFF (If active the UPS output turns off regardless of mode of operation. Auxiliary power, fan, communications and rectifier/battery charger shall remain functional. Restart initiated immediately when inactive.)

• Request Bypass (If active the UPS transfers to bypass if bypass voltage, frequency, and synchronisation are ok.)

• Request Normal (If active the UPS transfers to inverter operation if not prohibited by EPO or alarm condition.)

• Force Bypass (If active the UPS is forced to static bypass operation regardless of the bypass status.)

• External Battery Breaker Status (If active the UPS knows that the batteries are disconnected.)

• Building alarm 1-6 (These can be activated separately or at the same time with other building alarms.)

• Not in use (default)

• Shutdown (If active the UPS will shutdown immediately.)

• Delayed Shutdown (If active the UPS will shutdown after user configurable delay time. Restart initiated immediately when inactive.)

• Normal/Bypass (If active the UPS transfers to bypass if ok. If inactive the UPS transfers to inverter when possible.)

• Output transformer over temperature (If active the UPS output turns off after user configurable delay time.)

• Input transformer over temperature without bypass (If active the UPS will start to operate on battery or shutdown when batteries not available after one minute delay.)

• Input transformer over temperature with bypass (If active the UPS will start to operate on battery or transfer to bypass after one minute delay.)

7.3.4 EPO relay (option)

The Emergency Power Off (EPO) is a safety feature designed to power down the UPS in case of an emergency. The EPO relay is activated when control voltage (24VDC) is applied to it. The logic circuit will receive the signal and immediately turn off the output power of the UPS and open the battery circuit breaker (F1) disconnecting the battery power. After using EPO, the UPS unit needs to be started manually. The EPO relay can be ordered as factory installed.

Revision 1

7.3.5 Earth fault monitor (option)

The earth fault monitor is used to detect earth fault in UPS by monitoring the system's insulation resistance. The device is connected to the supply via terminals A1-A2. Terminal L is connected to the monitored voltage and PE terminal is connected to earth.

If the insulation resistance drops below the adjusted alarm value, the red LED goes on and the output relay switches off. The earth fault monitor is in auto reset mode when a bridge between terminals

LT1 and LT2 is connected. Now the output relay switches back on if the insulation resistance gets back to normal. Without the auto reset mode on, the insulation monitor remains in faulty state even when the insulation resistance gets back to normal and the reset needs to be done manually by pressing the reset button.

When the UPS is equipped with an internal Maintenance Bypass Switch (MBS), the control input X45 is reserved for the status information from the MBS. In this case the earth fault signal shall be taken straight from the terminals 11 and 14 of the earth fault monitor.

Figure 7-5: Earth fault monitor and the connection diagrams for 9155 and 9355 models

7.4 XSlot communication (option)

10 Parallel systems

10.1 Overview

Parallel UPS configurations are recognised as either redundancy or capacity systems. The redundancy system is used to improve the system reliability with N+1 redundant UPS module. The capacity system for its part provides the maximum output power without focusing to the highest system reliability.

A parameter selection is used to switch between the redundancy and capacity modes. It is important to remember that the mode is affecting to the output power rating and overall system reliability.

UPS modules of the parallel system share equally the load with Hot Sync

®

technology. The parallel outputs can be combined in a System Parallel Module or cabinet. It is the system component containing the obligatory service switches. Customer’s low-voltage distribution panel can also be used instead of the System Parallel Module. In the redundancy system, service switches enable the maintenance or service on an UPS module. In the capacity system, one needs to have a common system bypass switch to do the maintenance or service without safety hazards.

Figure 10-1: Parallel configurations with UPS modules

Field upgrading can be used to extend existing capacity/redundancy systems with UPS modules.

The upgrading must be carried out by service personnel from the manufacturer or from an agent authorised by the manufacturer.



User's Guide

P-164000341

Revision 1

10.2 Tie cabinets

The Tie Cabinets (TCs), provided by UPS manufacturer, has input connections up to three parallel

UPS modules. It is also possible to use two redundant UPS modules and one bypass connection. This bypass option can be used for service or test purposes.

NOTE

It is not allowed to feed the load simultaneously from mains (bypass) and inverter(s) of the

UPS unit(s). While turning the switch, where the bypass is connected, ON/OFF, UPS should be on static bypass mode or shut down.

NOTE

The maximum load supported by the system is limited to 15 kVA if there are two UPSs and bypass connected to TC (See wiring diagrams below).

Terminals of the TC have two or four wire connection (L1 and N or L1, L2, L3 and N) and ground terminals. The upper ground terminal is for a load cable and the lower ground terminal is for UPS units.

Table 10-2: Minimum cable and fuse rating for the different parallel system with installation procedure C * (system bypass not allowed)

NOTE

Protection fuses need to be used for load cabling if manufacturers Tie Cabinet (or similar) not used.

Required parallel system wiring length should be in accordance with the following rule, as referenced to the diagram below to ensure approximately equal current sharing when in static bypass mode (see

Figure below:

Total length of 1A + 1B

= Total length of 2A + 2B



This rule has a tolerance of approximately ± 10% for the combined input and output wire lengths. If installing only two UPS modules, this requirement is no longer required as each UPS is capable of supporting the full bypass requirement. However, this would preclude future expansion.

10.4 Parallel operations

Start-up:

NOTE

Before start-up make sure that UPS installations have been carried out correctly and ground connections of both UPS units and parallel module have been connected. Check also that the

XSlot Hot Sync cards are installed correctly and the communication line between UPSs is connected according to figure Communication cabling wiring.

When installation is completed correctly the start procedure can be started.

NOTE

If some settings are changed from User settings the same changes need to be done separately to all of the UPSs in the system.

Carry out the following procedure to each UPS you want to have in system:

1.

Turn the battery and input circuit breakers to ON position.

2.

UPS will enter a stand-by mode and starts to charge batteries with a cooling fan operational.

Output is without the voltage in the stand-by mode.

3.


4.

Select unit number in parallel system: Unit #1, Unit #2, Unit #3 or Unit #4. Select: SETTINGS ->

USER SETTINGS -> PARALLEL OPERATION SETTINGS -> PARALLEL UNIT NUMBER.

5.

Select minimum units to support load: 0-4. Select: SETTINGS -> USER SETTINGS -> PARALLEL

Shutdown:

While system is running and UPSs are supporting load, there are two different ways to perform a shutdown. The user can select either to shutdown the whole system or only one UPS.

1.

Select TURN SYSTEM OFF from the main menu => All the UPSs in the system will go to standby mode.

2.

Select TURN UPS OFF => Only the selected UPS will go to stand-by mode.

When UPS is in stand-by mode it still charges its batteries and uses cooling fans. Stand-by mode enables a fast restart. If some UPS or all the UPSs in the system need to be shutdown completely, proceed to item 3.

3.

Select TURN UPS OFF and press and hold the return button for 5 seconds. There shall be an indication sound during the hold.

4.

UPS shall do a shutdown routine.

5.

Turn the battery and input circuit breakers to off position to finalise the shutdown procedure.
