20 - 120 kVA
Installation and user manual
Introduction
Thank you for selecting an APC by Schneider Electric product to protect your electrical equipment.
The MGETM GalaxyTM 5000 range has been designed with the utmost care.
We recommend that you take the time to read this manual to take full advantage of the many features of your UPS.
APC by Schneider Electric pays great attention to the environmental impact of its products.
Measures that have made MGETM GalaxyTM 5000 a reference in environmental protection include:
the eco-design approach used in product development,
the elimination of harmonic disturbances reinjected into the AC source,
production in an ISO 14001 certified factory,
recycling of the MGETM GalaxyTM 5000 at the end of its service life.
To discover the entire range of APC by Schneider Electric products and the options available for the MGETM GalaxyTM 5000 range, we invite you to visit our web site, www.apc.com, or contact your local APC by Schneider Electric representative.
All products in the MGETM GalaxyTM 5000 range are protected by patents. They implement original technology not available to competitors of APC by Schneider Electric.
To take into account evolving standards and technology, equipment may be modified without notice. Indications concerning technical characteristics and dimensions are not binding unless confirmed by APC by Schneider Electric.

Safety
Safety rules
Safety of persons
The UPS must be installed in a room with restricted access (qualified personnel only, according to standard 62040-1-2).
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.
Dangerous voltage levels are present within the UPS. It should be opened exclusively by qualified service personnel. The UPS must be properly earthed.
The battery supplied with the UPS contains small amounts of toxic materials. To avoid accidents, the instructions 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.
Caution, wait five minutes before opening the UPS to allow the capacitors to discharge.
Caution, there is high leakage current, the earthing conductor must be connected first.
The product must be installed on a non-inflammable surface (e.g. concrete).
Caution, battery replacement must be carried out by qualified personnel.
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.
When replacing battery cells, use the same type and number of cells.
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 -25° 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 concerning the 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, vapour, salt air, bad weather or dripping,
-explosive dust and gas mixture,
-extreme temperature variations,
-bad ventilation,
-conductive or radiant heat from other sources,
-cooling water containing acid or impurities which may cause scale, silt, electrolysis or corrosion of converter parts exposed to water,
-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 standard IEC 60364-4-42: Protection from thermal effects.
standard IEC 60364-4-41: Protection from electric shock.
standard IEC 60364-4-482: Electrical installations of buildings.
in France, the requirements of standard NFC 15-100.

To ensure correct ventilation, leave nothing on top of the UPS.
Leave one meter of free space in front of the UPS for door opening.
The cabinet rests on four cylindrical feet, 40 mm in diameter, positioned in the four corners of the cabinet to spread the weight.
If 500 mm of free space is not maintained above the UPS, abnormal temperature rise may occur.
The UPS must be installed in a room with restricted access (qualified personnel only).
(*) The UPS can operate correctly back to the wall, but it is preferable to leave some space for easier maintenance.

The table opposite is an example for an installation with up to four UPS units.
For installations with redundant units, take into account only the number of units required to supply the loads (e.g. in a three-unit installation where one unit is redundant, only two units count in determining the input and load currents).
This table is valid for 400 V input and load phase-to-phase voltages, at rated load with a power factor of 0.8. For voltages of 380 or 415 V, multiply the current values by 1.05 or 0.96 respectively and, if necessary, modify the cable sizes accordingly.
The cable sizes in this table concern the bold sections in the diagram below.
(1) Cable sizes are determined for U1000 R02V type copper conductors (for aluminium conductors, increase the size by 30%). Size calculations also take into account a voltage of 400 V and grouping of four cables.
