MGETM GalaxyTM 7000
250 - 500 kVA
Installation manual
Introduction
Thank you for selecting an APC by Schneider Electric product to protect your electrical equipment.
The MGETM GalaxyTM 7000 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 (Uninterruptible Power System).
APC by Schneider Electric pays great attention to the environmental impact of its products.
Measures that have made MGETM GalaxyTM 7000 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 7000 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 7000 range, we invite you to visit our web site at www.apc.com or contact your local representative.
All products in the MGETM GalaxyTM 7000 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.
This document may be copied only with the written consent of Schneider Electric or its affiliated companies. Authorised copies must be marked

Safety
Safety rules
Safety of persons
The UPS must be installed in a room with restricted access in compliance with standard IEC 60364-4-482). Only qualified personnel are authorised to enter this restricted access room.
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. Caution, replacement of the battery by a battery of the wrong type can result in an explosion.
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 and disconnected last.
The product must be installed on a non-inflammable surface (e.g. concrete).
Caution, battery replacement must be carried out by qualified personnel.
Isolate the Uninterrptible Power Supply (UPS) before working on the circuits upstream.
The UPS can only be used in a controlled indoor environment.
Product safety
Protection (circuit breaker/switch disconnector) 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,
-poor 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 against electric shock.
standard IEC 60364-4-482: Electrical installations of buildings.
standard NFC 15-100 (in France).
the requirements of standard IEC 62040-1-2:

Position in room
UPS cabinets
The UPS must be installed in a room with restricted access (qualified personnel only).
|
To ensure correct ventilation, leave nothing |
|
on top of the UPS. |
>500 mm |
Leave one meter of free space in front of the |
|
UPS for door opening. |
>600 mm |
The cabinet rests on four cylindrical feet, 60 |
|
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 can operate correctly back to the |
|
wall, but it is preferable to leave some space |
|
for easier maintenance. |
|
The distance between the bottom panel and |
>300 mm |
the floor must be less than 10 mm. |
|

The table above is for 400 V interphase voltages and a load with a power factor of 0.9.
For other voltages (380 or 415 V), the current values must be multiplied by 1.05 and 0.96 respectively.
The battery current is an average current for a battery voltage of 488 V (44 blocks at 1.85 V/cell each), at Pn with a power factor of 0.9.
Recommended upstream protection
Normal AC source
Stick a label with the following text on each upstream circuit breaker / switch-disconnector: "Isolate Uninterruptible Power Supply (UPS) before working on this circuit".
Selection of protective devices is determined by the maximum continuous current (at 380 V). Protection ratings are calculated for the maximum continuous current (at 380V).

The circuit breakers / switch-disconnectors recommended above respect the requirements for discrimination with the UPS fuses.
Depending on the installation, the CB/SD may be replaced by a CB/SD with a higher breaking capacity.
* For short-circuit currents > 40 kA, use a CB/SD with a higher breaking capacity (type L or H).
Bypass AC source
Stick a label with the following text on each upstream circuit breaker / switch-disconnector: "Isolate Uninterruptible Power Supply (UPS) before working on this circuit".
Selection of protective devices is determined by the maximum continuous current (at 380 V). Protection ratings are calculated for the maximum continuous current (at 380V).

See the necessary precautions during connection of circuit breakers / switch-disconnectors in the installation manual of the battery circuit-breaker enclosure, doc. no. 34021529.
Recommended residual-current protection
Requirements for residual-current protection.
For common normal and bypass AC inputs
- The same residual-current protection may be used for the two lines.
For separate normal and bypass AC inputs
-A transformer is required upstream of either the normal AC line or the bypass AC line.
-Equip each line with a circuit breaker or switch-disconnector with residual current protection.
See “System earthing arrangements”, page 24.
The recommended minimum residual current protection is 3A, provided the conditions defined in IEC364.4-41 are respected.
