1.2 System description
– a rectifier-charger (RC) module converts 3-phase AC power from the Mains 1 supply into DC power for the normal inverter
input and float charges or recharges the batteries;
– a battery unit provides backup power for the inverter in the event of a voltage drop or a Mains 1 failure;
– an inverter module converts the DC power supplied by the rectifier-charger module or the battery unit into 3-phase AC
power for the load;
– an emergency bypass module ensures the instantaneous transfer of the load via the static switch to the Mains 2 bypass
line in the event of an inverter shutdown (initiated by the user or by a protective device) or a sudden overload;
– a maintenance bypass which isolates the UPS for maintenance and transfers the load without interrupting the supply of
power. The maintenance bypass is made up of three manual switches.
Note:
– the Mains 1 normal input and the Mains 2 bypass input have different functions and, depending on the installation, may be
protected differently upstream and/or come from different sources;
– frequency converters are available without backup batteries;
– the emergency bypass line and the maintenance bypass line do not exist in installations where the load frequency and the
Mains 2 frequency are different (for example in frequency converters);
– for reasons of redundancy and/or increased power, the rectifier-charger, inverter and battery modules (the UPS, part A in
the MGETM GalaxyTM 9000 schematic diagram above) may be arranged in parallel lines. In this case, an isolation function is
added to the output of each UPS for maintenance without disrupting the load.
In this type of system, the components of part B in the diagram are located in a separate cubicle referred to as the "Static
Switch Cubicle".
The system may also include:
– an isolating transformer on the Mains 2 line;
– a harmonics filter on the Mains 1 input;
– different remote control, indication and display systems;
– a double bridge rectifier-charger module.

The power necessary for the load is provided by Mains 1 through the rectifier-charger and the inverter.
The rectifier-charger also supplies the power to float charge and recharge the battery (1).
The rectifier-charger output voltage (DC) is regulated for the different battery types and charging modes:
– vented lead-acid or Ni/Cd batteries: two different voltages, one for float charging and one for recharging;
– sealed lead-acid batteries: a single voltage for both charge functions.
The voltages depend on the number of battery cells and the battery manufacturer. They can be factory set and are adjustable
by the after-sales support technicians.
An optional electronic board may be used to continuously measure the battery temperature and automatically adjust the
voltages.
Parallel UPS systems:
the power drawn by the load is equally shared between the different UPSs.

Introduction
Operation with Mains 1 down
(figure 12)
In the event of a Mains 1 failure or Mains 1 voltage outside specified tolerance of –10 % in amplitude (–15 % optionally), the
rectifier-charger stops and the battery supplies the necessary backup power to the load via the inverter. The battery, floatconnected between the rectifier-charger and the inverter, discharges during this operating mode.
The green "load protected" light 5 on the control panel is on.
The user is warned of battery operation by a buzzer and the orange "load on battery" light 4 on the control panel.

This information is also available via volt-free changeover contacts for remote control devices.
In this case, there is a 30 seconds delay.
Note:
In the event of a Mains 1 failure, frequency converters without a battery shut down and the load is no longer supplied.

Battery time
The available battery time during a Mains 1 outage depends on the:
– rated capacity of the battery;
– power consumed by the load;
– temperature of the battery;
– age of the battery.
The specified battery time corresponds to a minimum duration at full rated load.
The actual backup time can therefore be greater if the system operates below its full rated load during the Mains 1 outage.
Operation on battery power can be extended beyond the specified time by reducing the load power consumption
(by disconnecting non-critical loads).
A "low battery shutdown" warning signal is sent via volt-free changeover contacts for remote control devices when the battery
voltage reaches a level slightly above the minimum level. This signal warns the user of the imminent end of battery power.
On the device itself, the buzzer beeps increasingly rapidly and loudly.
Battery power stops when the voltage supplied by the battery reaches the voltage minimum (340 V). This results in inverter
shutdown and transfer of the load without interruption to Mains 2. The red "load not protected" light 2 on the control
panel is on.
beep...beep...
!
!
+–

If Mains 2 also fails, the load is no longer supplied. Normally, the inverter shuts down when the time on the battery power
exceeds three times the specified backup time.
Note:
As an optional function (battery time estimator), the "low battery shutdown" warning signal can be sent with an adjustable time
delay prior to the effective end of battery power.

Introduction
Operation with Mains 1 restored
(figure 13)
When Mains 1 power is restored or its voltage returns to within specified tolerances, the system automatically returns to its
normal operating mode described above (on the condition it did not reach the end of battery power).
If the end of battery power was reached (with the resulting inverter shutdown), the RC restarts automatically, but the inverter
must be restarted manually, either locally or remotely in systems equipped with a remote-control unit.
The rectifier-charger recharges the battery which was discharged during the Mains outage.
Note:
In frequency converters without battery power, the return of Mains 1 power results in the automatic restart of the RC and the
inverter.
Battery charge cycle

mains 2

load
battery
Fig. 13
The battery charge cycle takes place in two steps (see figure 14):
– step 1: the battery is recharged at a constant current limited to 0.1C10 (i.e. 1/10th of the battery capacity specified
for a 10 hour discharge). The DC voltage increases with the battery charge until the charge level is reached;
– step 2: the battery is recharged at constant voltage equal to the charge level (maximum value 463 V).
The charging current gradually decreases until reaching a specified low value (floating current).
For vented lead-acid batteries, the rectifier-charger supplies the charging voltage for 0 to 255 hours (parameter defined by
the after-sales support department) and then the floating voltage. For sealed lead-acid batteries, the charging and floating
voltages are the same.
Note:
If the Mains 1 failure is shorter than 0 to 255 seconds (parameter defined by the after-sales support department), the charger
does not initiate a complete charge cycle but automatically supplies the floating voltage.

Introduction
Installation with an engine generator set
(figure 15)
If a stand-by generator is included in the installation, it is generally started automatically in the event of a Mains failure and
connected to the main low voltage switchboard.
It is disconnected when Mains power is restored.
With such a system, the required battery time may be reduced to the time necessary for starting and bringing on line the
stand-by generator.
The battery supplies power to the inverter during the transfers: Mains - generator and generator - Mains.
The transfer sequences described: Mains - battery - generator and generator - battery - Mains are fully automatic.
They in no way affect the load and require no manual operation by the user.
Note:
To avoid load surges on the generator, the rectifier/charger is started with a 10 second maximum current consumption walk-in.

UPS shutdown or overload (systems with a static switch module) (figure 16)
Single-unit UPSs, modular UPSs or UPSs with an SSC:
– in the event of a UPS shutdown (initiated by the user or by an internal protective device), the load is automatically
transferred to the Mains 2 bypass line. If transfer conditions are correct, transfer takes place instantly, without interruption to
the load.
Note:
Transfer conditions are not correct when Mains 2 characteristics are outside tolerances (voltage: ±10 %; frequency as per
personalization; phase sync with inverter ±3°);
– in the event of a major transient overload (greater than 160 % of the full load), immediate transfer takes place as above,
without interruption to the load.
When the overload disappears, the load is automatically returned to the inverter depending on the configured value of the
re-transfer counter: no return to inverter, or 1 to 255 (personalized value) overloads accepted before the load is permanently
transferred to Mains 2. This operating mode allows start-up of load devices causing high inrush currents.
This system requires correct transfer conditions. If the conditions are not correct, the inverter will current limit to 150 % of its
rated current for 1 second before stopping;
– in the event of a small but extended overload (i.e. a continuous level of power exceeding the full rated load), the inverter
will continue to supply power for a period depending on the magnitude of the overload (10 minutes for a 125 % overload,
1 minute for a 150 % overload). See figure 17 (Overload curve);
– in all three of the above cases, the inverter shutsdown and supplies the load via Mains 2 with the following information
on the control panel:
– green "load protected" light 5 off,
– buzzer 1 on,
– red "load not protected" light 2 on.

Introduction
Frequency converters without redundancy
– in the event of a shutdown, the load is no longer supplied with power;
– in the event of a major transient overload (greater than 160 % of the rated load), the inverters will current limit to 160 %
of their rated current for 1 second before stopping;
– in the event of a small but extended overload (i.e. a continuous level of power exceeding the full rated load), the inverters
will continue to supply power for a period depending on the magnitude of the overload (10 minutes for a 125 % overload,
1 minute for a 150 % overload, see figure 17), and then stop;
– in all three of the above cases, inverter shutdown results in the following on the control panel of the concerned unit:
– green "load protected" light 5 off,
– buzzer 1 on,
– red "load not protected" light 2 on.
Frequency converters with redundancy
– the shutdown of one unit is of no consequence for the load. The other lines each take up an equal amount of load power
and the load continues to be supplied normally;
Inverter shutdown results in the following on the control panel of the concerned unit:
– green "load protected" light 5 off,
– buzzer 1 on,
– red "load not protected" light 2 on.
– in the event of an overload, the system only loses its redundancy as long as the overload is less than the total rated power
of the functioning units. If the overload is greater, the operating mode is that previously described for systems without
redundancy.

Output voltage quality and continuity
The output voltage is stable in amplitude and frequency and is free of interruptions or transients outside specified tolerances,
irrespective of Mains 1 or load disturbances (outages, load step changes, etc.).
Steady state voltage regulation:
For stable or slowly varying load conditions, the inverter output voltage is regulated to within ±0.5 % in amplitude.
The frequency of the output voltage can theoretically be regulated to within 0.1 % of the rated value, however the output
frequency range may be intentionally extended to a maximum of ±2 Hz so that the inverter can remain synchronized with
Mains 2 and its inherent frequency fluctuations, thus enabling transfer of the load to the bypass line at any time.
Note:
The output frequency range can be personalized and if necessary modified on the customer site by a qualified support
technician from ±0.25 Hz to ±2 Hz in 0.25 Hz steps.
When the Mains 2 voltage moves outside this frequency range, the inverter is desynchronized and operates in "free running"
mode, with the output frequency regulated to a high level of accuracy by a quartz oscillator.
When the Mains 2 frequency returns to within the specified tolerances, the inverter is gradually re-synchronized to the bypass
line at a rate of 0.5 Hz to 2 Hz/s (as per the value personalized by the after-sales support department), thus avoiding exposing
the load to sudden frequency variations.
Transient voltage regulation:
The inverter output voltage is not notably affected by instantaneous major variations in load characteristics.
This is due to the PWM (Pulse Width Modulation) chopping technique and the microprocessor-based regulation system that
instantly compensates for any variation. In particular, the inverter output voltage remains within ±5 % of the rated voltage for
load step changes of 25 to 100 % or of 100 to 25 %.

Control panel
3.1 Visible control panel
Located in the upper left part of the cubicle front, the visible panel is designed to provide an easy and rapid overview of system
status (see figures 22 and 23).
Interpretation of symbols is very simple and requires no particular training.
The information concerns only the cubicle on which the panel is located.
The panel indicates:
– normal operation (load protected);
– abnormal situations (operating problem);
– dangerous situations (load not protected);
– operation with load on battery power.
The control panel on the Static Switch Cubicle provides important information for the load:
– normal operation (load protected and supplied by the UPSs);
– abnormal situations (system malfunction);
– dangerous situations (load not protected).

The buzzer sounds in the following situations:
– load supplied by Mains 2;
– load on battery;
– operating problems.
It beeps at a low decibel level and slow rate for minor problems and when the load is supplied from battery power.
When the "low battery shutdown imminent" warning is received, the beeps increase in decibel level and rate.
Finally, if the inverter shuts down, the beep is loud and continuous. A buzzer reset button is located on the hidden control
panel. If the buzzer is reset, a higher level alarm will set it on again.

This red light 2 signals that:
– the load is supplied by Mains 2 following inverter shutdown (initiated by the user or by a protective device or a sudden
overload) or the opening of the inverter output switch Q5N;
– battery circuit breaker QF1 has opened, thus making battery power unavailable.
Note:
In a parallel system, this light concerns only the specific UPS. The load may still be protected by the other lines.

This green light 5 signals that the load is supplied by the inverter and that the specified battery time is available in the event
of a Mains 1 outage. In short, it signals that the system is operating normally.
Note:
In parallel systems, this light concerns only the specific UPS.
The load may not be protected if it depends on the other lines. It is necessary to take into account all the "load protected"
lights 5 for the different system lines or the light on the control panel of the Static Switch Cubicle, if it exists.

6
This green button 6 is used to locally start the inverter. When it is pushed, the green "load protected" light 5 blinks for
3 seconds, indicating that the start-up order has been received. When the inverter has synchronized with Mains 2, it supplies
the load and the green "load protected" light 5 remains on. The load is supplied by the UPS and the system is functioning
normally. If the transfer to Mains 2 conditions are not correct (Mains 2 voltage, frequency or phase conditions outside
tolerances), the inverter will not start and the system awaits a special order (see the "Hidden control panel" section).
Note:
– for modular UPSs with external maintenance bypass or parallel UPSs with SSC, transfer of the load to the inverters takes
place only when the number of operating lines required to supply the load has been reached;
– for frequency converters, inverter start-up must take place with the load off or drawing a quantity of power equal to or less
than that supplied by a single UPS.
"Inverter off" button

7
This gray button 7 turns the inverter off.
– press the "inverter off" button 7 for 3 seconds;
– if the transfer to Mains 2 conditions are correct:
– the load is transferred without interrupting to Mains 2,
– the inverter shuts down,
– the green "load protected" light 5 goes off and the red "load not protected" light 2 goes on.
– if the transfer to Mains 2 conditions are not correct, the button produces no effect. A special function on the hidden panel
may be used to force the transfer.
Caution:
If the transfer is forced, the load will be subjected to a 0.8 second interruption in the supply of power.
Note:
– for Modular UPSs or parallel UPSs with SSC, the shutdown of an inverter may or may not result in the transfer of the load
to Mains 2, depending on redundancy conditions;
– if the transfer to Mains 2 conditions are not correct or if the system does not have a Mains 2, the shutdown of a single
inverter will result in the shutdown of the entire system if there is no redundancy.

6. Alarms
The autodiagnostic system considers any system status other than normal as a problem.
Prior to any other action, note any lights (A to N) on the hidden control panel that may be on.
Also note any messages on the screen.
Certain problems may result in the control panel not functioning.
In this case, it is strongly recommended to call the after-sales support department.
– if the load is still correctly supplied with power, it has probably been transferred to Mains 2 (static switch) and is therefore
no longer protected;
– if the load is no longer supplied with power, transfer it manually to the maintenance bypass (see section below).
6.1 Maintenance bypass
This operation is possible only if the system includes a Mains 2. It results in the load being directly supplied by Mains 2 via
maintenance bypass switch Q3BP, thus ensuring a higher level of security in the event of a malfunction.
Important:
Prior to beginning the bypass operation, shut down all system inverters (press the "inverter off" button 7 on each UPS
control panel). If an inverter remains operating and the Mains 2 transfer conditions are not correct, the load will suffer a 0.8
second interruption.
Switching procedures are explained on a drawing next to each switch. It is imperative that the operation proceed in the
following order:
– shut down any inverters that may still be running;

Note:
– in systems with a Static Switch Cubicle, the above operation is carried out in the Static Switch Cubicle;
– the operation with the three switches is carried out in reverse order (3, 2, 1) to return to normal status;
– in an installation comprising modular UPSs with an external maintenance bypass, the operation is carried out in the external
maintenance bypass. The cubicle is not equipped with a Q4S switch and it is therefore necessary to open the protection
devices upstream on the maintenance-bypass line.

Signal reception
The signals should be provided by volt-free contacts.
– emergency shutdown. An NC contact causes:
rapid shutdown of the inverter and the RC,
opening of battery circuit breaker QF1,
transfer of the load to Mains 2 (generally without interruption in the supply of power);
– battery room ventilation fault: a NO contact causes the shutdown of the RC;
– battery circuit breaker QF1 closed: a NO contact inhibits inverter start-up when the breaker is open;
– battery temperature: an optional PC-board may be connected to the remote transmission board. It supplies information
on the battery temperature, thus enabling the RC to regulate the battery voltage.
Note:
The Static Switch Cubicle does not receive any of the above signals.
Signal transmission
– an auxiliary 24V power supply, isolated and backed up, is used to supply:
the undervoltage coil release for the battery circuit breaker(s) QF1,
an optional board that measures the temperature in the battery room;
– "general alarm" information (2 volt-free changeover contacts) which includes:
internal faults,
information on temperatures outside tolerances in the battery room (optional),
overload information (I > In),
static switch ventilation and power-supply faults;
– "low battery shutdown" warning signal (2 volt-free changeover contacts) indicating that battery time is about to run out.
The warning threshold may be personalized;
– "load on inverter" signal (2 volt-free changeover contacts) indicating that the load is supplied by the inverter. In singleunit UPS systems, one volt-free changeover contact may be used to indicate that the load is supplied by Mains 2;
– "load on battery" signal (2 volt-free changeover contacts) indicating that the inverter is supplied by the battery in the
following cases:
Mains 1 outage or voltage drop,
RC shutdown,
RC current limiting;
This signal, which may be used to initiate process saving and shutdown procedures, is time-delayed by 30 seconds to avoid
unnecessary operations following micro-breaks;
– "maintenance position" signal (2 volt-free changeover contacts) indicating that:
maintenance bypass switch Q3BP is closed,
Mains 2 input switch Q4S is open,
inverter output switch Q5N is open,
battery circuit breaker QF1 is open;
– signal to open battery circuit breaker(s) QF1 in the event the "emergency shutdown" button being pressed or to avoid
an excessive battery discharge (more than 3 rated time).
Note:
– the maximum breaking capacity of the changeover contacts is 5 A at 250 V;
– information on the battery is not supplied to frequency converters without a battery or to the Static Switch Cubicle;
– in systems with a Static Switch Cubicle, the "load on inverter" and "maintenance position" signals must be directed to the
Static Switch Cubicle.

Environment information
Signal reception
The signals should be provided by volt-free contacts.
– "desynchronization with Mains 2" signal inhibits the inverter from synchronizing its output frequency with that of
Mains 2. The inverter supplies a stable frequency and the load may no longer be correctly transferred from the inverter to
Mains 2. In the event of a malfunction or an overload, the transfer will take place with a 0.8 second interruption in the supply
of power to the load;
– "gradual rectifier/charger shutdown" signal makes the rectifier/charger shut down progressively to avoid excessive step
load variations in the event of a low output engine generator set replacing Mains 1;
– "generator current limiting" signal makes the rectifier/charger current limit the power drawn when a low output engine
generator set has replaced Mains 1. The additional power required for the inverter is supplied by the battery;
– "battery charge current limiting" signal reduces the battery charge current (programmable parameter) in the event a low
output engine generator set has replaced Mains 1;
– "transfer to Mains 2 disabled" signal blocks transfer of the load from the inverter to Mains 2. In the event the inverter
shuts down (overload, etc.), the load is no longer supplied (for modular UPSs, this information is disabled and transferred to
an auxiliary output);
– "transfer to Mains 2 with interruption disabled" signal blocks transfer of the load from the inverter to Mains 2 if it would
result in an interruption in the supply of power to the load. Only no-break transfers are allowed, i.e. transfer to Mains 2
conditions must be correct or the transfer is disabled (for modular UPSs, this information is disabled and transferred to an
auxiliary output);
– "auxiliary" signal can be used to provoke (depending on personalization):
a forced shutdown of the inverter (regardless of the status of Mains 2),
a protected inverter shutdown (transfer of the load to Mains 2 without interruption only if it is within tolerances),
modification of the inverter output frequency (50 Hz or 60 Hz);
– "remote inverter on" signal can be used to remotely start the inverter;
– "remote inverter off" signal can be used to remotely shut down the inverter.
Note:
In a system with a Static Switch Cubicle, the following signals must be directed to the Static Switch Cubicle:
– desynchronization with Mains 2,
– transfer to Mains 2 disabled,
– transfer to Mains 2 with interruption disabled.
Signal transmission
These signals are each transmitted by two volt-free changeover contacts with a maximum breaking capacity of 5 A 250 V.
– "overload" signal indicates that an overload has taken place (Pload > Pnominal in kVA);
– "rectifier/charger function fault" signal indicates that:
– a fault has taken place in the rectifier/charger module,
– Mains 1 input switch Q1 is open;
– "inverter function fault" signal indicates that a fault has taken place in the inverter module;
– "transfer to inverter fault" signal indicates that the load transfer conditions from Mains 2 to the inverter are incorrect;
– "transfer to Mains 2 fault" signal indicates that the transfer to Mains 2 conditions (voltage, frequency or phase) are
incorrect and a forced transfer will result in a 0.8 second interruption in the supply of power to the load;
– "rectifier/charger on" signal indicates the status of the module.
Note:
A Static Switch Cubicle receives only the following signals:
– overload,
– transfer to inverter fault,
– transfer to Mains 2 fault.

To service a number of modular UPSs with an external maintenance bypass, it is necessary to isolate them.
– isolate the UPSs
Proceed in the following order:
– shut down each inverter (press the "inverter off" button 7 for three seconds),
– switch to the maintenance bypass whereby the load will be directly supplied by Mains 2 via Q3BP (close Q3BP, then open
Q5 in the maintenance bypass cubicle),
– open input switch Q4S on each UPS;
– isolate each UPS from Mains 2 by opening the upstream protection devices,
– open input switch Q1 on each UPS,
– open output switch Q5N on each UPS.
The UPSs are de-energised (except the Mains 1 cables upstream of the Q1 switches on each UPS), but the load is supplied
with Mains 2 power via the maintenance bypass. Complete isolation of the installation requires opening of the upstream
protection devices on both Mains 1 and Mains 2.
– start-up
Once servicing is completed, proceed in the following order:
– close the input switches Q1 and Q4S on each UPS,
– close output switch Q5N on each UPS,
– close output switch Q5N in the maintenance bypass cubicle,
– open switch Q3BP in the maintenance bypass cubicle,
– close battery circuit breaker Q1 on each UPS,
– start all the inverters (press the "inverter on" button 6 ).
The UPSs all come on line at the same time if they are sufficient in number to supply the load.

Maintenance
8.2 Battery maintenance
Consult the instructions supplied by the battery manufacturer. Below are a few general indications:
– sealed lead-acid batteries.
These batteries require no maintenance:
but check the terminals of each cell from time to time and clean if necessary;
– vented lead-acid batteries:
check the electrolyte level regularly and add water if necessary,
check the voltage of each cell to determine if it is necessary to equalize the battery,
check the terminals of each cell and clean if necessary.
Caution:
Battery maintenance is undertaken with the system powered up. Operations must be carried out in accordance with applicable
safety regulations by qualified personnel using insulated tools, gloves and safety goggles.
Batteries contain dangerous substances that will harm the environment if thrown away. If you change the batteries yourself,
call on qualified organizations for battery disposal and recycling.

8.3 Autodiagnostics
Note the indications supplied on the hidden control panel (lights A to N 8 ). See the "control panel" section.
In systems with one or several alphanumeric displays, check the list of alarms.
If there is a true malfunction, note the indications and alarms and call the after-sales support department.
8.4 Visual check
– after-sales support technicians will power down the system prior to any maintenance operations.
Note:
In redundant, parallel UPS systems and frequency converters, the check may be carried out successively on each UPS or
converter without interrupting the load. In other configurations and for the Static Switch Cubicle, the load must be supplied via
the maintenance bypass (see the "Alarm" section).
– clean the system regularly, particularly the air inlet and outlet grills. Check that the air circulates freely in the cubicles.
– Use a vacuum cleaner if necessary;
– check that nothing hinders the ventilation at the top of the system;
– check that all the fans operate correctly.
8.5 Functional check
– check that lights J, K, M and N on the hidden control panel are not on to avoid an interruption in the supply of power to
the load due to incorrect transfer conditions or a battery problem;
– press the "inverter off" button and check that the buzzer and control panel lights function correctly (see the "main operating
modes" section);
– press the "inverter on" button and check again that the control panel lights function correctly;
– run a transfer to battery test. With the inverter on, open input switch Q1.
The orange "battery" light on the control panel should light. After two minutes on battery power, close input switch Q1.
The rectifier/charger should automatically restart and the orange "battery" light on the control panel should go off;

Options
10.7 Double bridge rectifier-charger
This option reduces the reinjection of harmonic disturbances into Mains 1, but to a lesser extent than the harmonics filter.
The double bridge rectifier-charger replaces the MGETM GalaxyTM 9000 UPS's standard input rectifier-charger.
10.8 Battery "Temperature Monitor"
An electronic PC-board measures the battery temperature. The rectifier/charger uses this information to adjust the battery
charge current to the temperature in view of:
– optimizing battery recharge;
– obtaining maximum battery time;
– ensuring maximum battery life.
10.9 Empty cubicles
Cubicles may be supplied empty, thus enabling users to make up their own auxiliary cubicles (battery cubicles or other) or
panels and meet the particular demands of each installation. In this way, the entire electrical installation will have a uniform
appearance.
