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.

Safety

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:

For separate normal and bypass AC lines from a single source.

It is essential to transform the UPS internal PE bar into a PEN bar, See “Adapting the cabinet according to the neutral point
connection”, page 26.
For an installation with a SSC cabinet or an external bypass cabinet, it is essential to transform the cabinet's internal PE
bar into a PEN bar, See “Adapting the cabinet according to the neutral point connection”, page 26.

Unit or modular UPS

The UPS output neutral must be connected to the internal PEN bar (1)

Parallel UPS with SSC cabinet or modular UPSs with external bypass cabinet:

The SSC cabinet output neutral or external bypass cabinet output neutral must be connected to the internal PEN bar for
this cabinet.
The connection between the UPS outputs and the SSC cabinet or the external bypass cabinet must be done in TNC
(connect the PEN cable to the PEN bar).

The load neutral terminal on the UPS, SSC or external bypass cabinet must not be used.
The SLT downstream TNS or TT starts on the MGE ™ Galaxy™ 7000 installation output.

In normal operating mode

The CPI1 controls the whole installation including downstream from the UPS. Power to the CPI2 is switched off by the R2
relay which controls voltage presence upstream from the UPS.

If the voltage is cut or the protection is opened upstream:

The R1 relay cuts the CPI1 circuit and the R2 relay closes the CPI2 circuit thus maintaining control downstream of the UPS.

Caution.

In the UPS or the SSC, the general shutdown causes UPS shutdown and opening of the battery circuit breaker (with
opening of the bypass static switch depending on personalisation settings).
The Emergency Power Off (EPO) notion is applicable to installations where pressing the button also causes the
circuit breakers on the upstream normal AC source and bypass AC source to open.
In parallel configurations, there must be a single general shutdown button with a separate contact for each UPS unit.

1. Remove the jumper on the XM19
