General UPS description
The UPS systems described in this manual are on-line, double conversion; the inverter included in the UPS always supplies energy to the load, whether the mains is available or not (according to the battery autonomy time).
This configuration guarantees the best service to the user, as it supplies clean power uninterruptedly, ensuring voltage and frequency stabilization at nominal value. Thanks to the double conversion, it makes the load completely immune from micro-interruptions, from excessive mains variations, and prevents damage to critical loads. The UPS uses IGBT technology with a high switching frequency in order to allow a low distortion of the current re-injected into the supply line, as well as high quality and stability of output voltage. The components used assure high reliability, very high efficiency and maintenance easiness.

• Rectifier [3]
  It converts the three-phase voltage of the AC mains into continuous DC voltage using a three-phase fully controlled IGBT bridge with a low harmonic absorption.
  The control electronics uses a microprocessor of latest generation that allows to reduce the distortion of the current absorbed by mains (THDi) to less than 5%. This ensures that the rectifier does not distort the supply mains, with regard to the other loads. It also avoids cable overheating due to the harmonics circulation.

• Battery charger / Booster [6]
  A bi-directional DC/DC converter is placed between the battery and the DC bus.
  The converter has a double function. When the mains is present and the rectifier operational the converter works as battery charger, restoring the energy lost by the battery and keeping it in floating charge. In case of mains or rectifier failure the battery supplies energy to the inverter through the converter, which works as booster stage.
  As the mains is back the rectifier provides energy to the inverter and the converter restores its function as battery charger.

• Inverter [4]
  It converts the direct voltage coming from the rectifier or from the DC battery into alternating AC voltage stabilized in amplitude and frequency.
  The fully digital control of the output sinewave allows to achieve high performances, among which a very low voltage distortion even in presence of high-distorting loads.

• Battery
  The battery can be installed inside or outside the UPS.
  The battery is charged every time it has been partially or completely discharged. When its full capacity is restored, it is kept floating to compensate for any self-discharge.

• Static bypass [5]
  The static bypass allows to transfer the load between Inverter and Bypass and vice-versa, in a very short time, and uses SCR’s as power commutation elements.

• Maintenance bypass [2]
  The maintenance bypass is used to cut off the UPS completely, supplying the load directly from the input mains in case of maintenance or serious failure

UPS operating modes

The UPS has four main operating modes.

Normal operation

• During normal operation all the circuit breakers/isolators are closed, except for MBP (maintenance bypass).
• The rectifier is supplied by the AC three-phase input voltage, feeds the inverter and compensates mains voltage as well as load variations, keeping the DC voltage constant. The battery charger keeps the battery charged (floating or boost charge depending on the battery type). The inverter converts the DC voltage into an AC sinewave with stabilized voltage and frequency and supplies the load via its static switch SSB.

Bypass operation
The load can be switched to bypass either automatically or manually. The manual changeover can be performed by display forcing the load to bypass. In case of failure of the bypass line, the load is switched back to inverter without interruption. Battery operation

• In case of power failure or rectifier fault, the battery feeds the inverter without interruption through the booster converter. The battery voltage drops based on the amplitude of the discharging current. The voltage drop has no effect on the output voltage, which is kept constant by changing the PWM modulation. An alarm is activated when the battery is near the minimum discharge value.
• In case the supply is restored before the battery is completely discharged, the system will be switched back to normal operation automatically. In the opposite case, the inverter shuts down and the load is switched to the bypass line. If the bypass line is not available or is out of tolerance, the loads supply is interrupted as soon as the battery reaches the discharge limit threshold (black-out).
• As soon as the supply is restored, the battery charger will recharge the battery. In the standard configuration, the loads are supplied again via static switch SSB when mains is available again. The inverter is restarted when the battery has partially restored its capacity.

Maintenance mode
The maintenance bypass operation is necessary whenever the UPS functionality is tested, or during maintenance or repair work. During this mode, the UPS is completely shut down and the load is directly supplied by the bypass line .

WARNING
Potential risks can be drastically reduced by wearing the Personal Protective Equipment listed in this chapter, which are indispensable. Always operate with due care around dangerous areas marked by the appropriate warning notices on the equipment.

General warnings

• DANGER
  • The UPS works with dangerous voltages. Only skilled technicians qualified and authorized by LEGRAND must perform the installation and ordinary maintenance operations.
  • No part of the UPS can be repaired by the operator.
  • Extraordinary maintenance operations must be carried out by LEGRAND Technical Support Service personnel.
• DANGER
  • Before beginning any installation and/or maintenance operation, make sure that all the DC and AC power sources are disconnected.
  • The UPS and the external battery cabinet, if present, must be installed with an earth connection to avoid high leakage currents. First connect the earthing cable.
  • Check during each installation and/or maintenance operation the continuity of the earthing system.
• DANGER
  • The UPS is powered by its own DC energy source (batteries). The output terminals may have a dangerous voltage even if the UPS is not connected to the AC power network.
  • Disconnect all batteries before performing any installation and/or maintenance operation
• WARNING
  • A battery can present a risk of electrical shock and burns by high short-circuit circuit current.

Failed batteries can reach temperatures that exceed the burn thresholds for touchable surfaces. The following precautions should be observed when working on batteries:

1. remove watches, rings or other metal objects.
2. use tools with insulated handles.
3. wear rubber gloves and boots.
4. do not lay tools or metal parts on top of batteries.
5. disconnect the charging source prior to connecting or disconnecting battery terminals.
6. determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground.
7. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock can be reduced if such grounds are removed during installation and maintenance (applicable to equipment and remote battery supplies not having a grounded supply circuit).
8. never leave live cable terminals without an insulated protection.
9. When replacing batteries, replace with the same type and number of batteries or battery packs. There is the risk of explosion if batteries are replaced by an incorrect type.

Do not dispose of batteries in a fire. The batteries may explode.
Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. The batteries installed inside the cabinet must be disposed of correctly. For the disposal requirements refer to local laws and relevant standards.

INDICATION
The UPS functions with TT, TN-C and TN-S systems. Input/Bypass and output neutral are not referenced to the same neutral potential.
For TN-C systems, it is necessary to bridge together the input, bypass and output neutral on the terminals during the installation.

CAUTION
