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 MGE
TM
GalaxyTM 6000
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.
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, float-connected 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.

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.

Introduction (cont.)
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 non­critical 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.
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.
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 463V). 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,
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 (340V). 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.

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
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 (cont.)
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.
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.

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);

Introduction (cont.)
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.

(minutes)
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 +/-2Hz 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.
Fig. 17
Note:
The output frequency range can be personalized and if necessary modified on the customer site by a qualified support technician from +/-0.25Hz to +/-2Hz in 0.25Hz 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 0.5Hz to 2Hz/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%.

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 26 and 27). 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.

"Inverter on" button
!
+–
!
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
O
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
O
UPS.

The hidden panel, located behind the hinged cover, offers the following indications and control functions:
environment faults;general faults in system modules;special control buttons
(see figure 28). This panel is identical for all types of cubicles, however, the controls or indications 8 that do not concern a given cubicle are not activated.
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
O
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.

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.
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;
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).

"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 (50Hz or 60Hz);
"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.

The load is supplied by the inverter, but Mains 1 is down or outside tolerances and power is supplied by the battery.
REMAINING BAT. TIME __MN %KW LOAD =___
This message is automatically displayed for five seconds, alternating with the preceding. It indicates the remaining battery time in minutes prior to inverter shutdown. The calculation takes into account:
the percentage of full rated load
power being drawn;
the type of battery;battery temperature;battery age.
LOW BATTERY SHUTDOWN IMMINENT !
This message replaces the "Mains 1 problem, load on battery" message when battery voltage reaches the "low battery shutdown" warning level. It alternates with the message described above, "remaining battery time…". The user must then rapidly take measures to secure the load (load shedding, file saves and shutdown,
etc.). In the next one to two minutes at most, the inverter will shutdown and the load will be interrupted. Two low battery thresholds exist:
a battery voltage threshold, which is
slightly above the threshold causing an inverter shutdown (this threshold can be disabled);
a time threshold, which refers to an
adjustable value of the time remaining before effective end of battery power.
ALARM ...
!
This message signifies that the battery circuit breaker is open and the inverter shut down. The cause of the alarm is in the list of secondary alarms (see next page).

The "Vision" display may be installed in all types of cubicles (UPS or Static Switch Cubicle).
Installed in a special enclosure, the "Remote vision" display provides the user with remote indications on system status.
The "Vision" display can operate in two different modes:
mono-cubicle: the "Vision" display
monitors only the cubicle in which it is installed;
multi-cubicle: "Vision" display can
monitor all system cubicles (up to eight maximum). In this mode, the system is equipped with only one "Vision" display which may be installed in any of the cubicles.
Insulating and Mains 1, Mains 2 and load voltage matching transformer
This transformer may be used to match Mains 2 voltage to that of the inverter, to create galvanic insulation between the load and the Mains or to create the appropriate neutral system.
Harmonics filter and power factor improvement
This option, placed on the Mains 1 input upstream from the inverter, reduces the reinjection of harmonic currents into the mains. Harmonic reinjection, produced by the rectifier/ charger, increases distortion on the mains. The amount of the increase depends on the source impedance. The reduction in distortion reduces the risk of disturbing other sensitive loads connected to the mains. The filter can also increase the power factor upstream from the inverter.
Three types of filter are available:
uncompensated filter for the
advantages listed above;
compensated filter for the
advantages listed above and to limit the capacitive current absorbed by the filter (additional inductance), in the event the UPS is supplied by an engine generator set;
phase shift filter, an economical
solution to limit the reinjection of harmonics on the mains.
Page 48 - 6739380EN/JC
Double bridge rectifier-charger
Battery "Temperature Monitor"
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
TM
MGE
input rectifier-charger.
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.
