Important Safety Information

To reduce the risk of fire or electric shock, install the UPS in an indoor environment that is free of conductive contaminants. This equipment is intended only for installations in a location that is restricted to qualified personnel.

The UPS is subject to high leakage current. The UPS must be connected to an earth ground before the supply is connected.

Hazardous voltages are present when the enclosures of the UPS are open. The UPS should only be serviced by personnel that are qualified to work on equipment that contains high voltage.

Standards, specifications, and designs are subject to changing. As required, ask for the confirmation of the information that is provided in this publication.

Note: This equipment complies with the limits for a Class A digital device according to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.

Installation

The UPS must always be installed in compliance with the following standards:

IEC 60364-4-42 - "Protection Against Thermal Effects"

IEC 60364-4-41 - "Protection Against Electric Shock"

IEC 60364-4-482 - "Electrical Installations of Buildings"

NFC 15-100 - Standard for low voltage that applies only for installations in France

Safety of Persons

The UPS must be installed in a room with restricted access. In accordance with "Standard 62040-1-2", only qualified personnel should have access to the room. A UPS has a battery as an internal power source. The power outlets may be energized even if the UPS is disconnected from the AC power source.

Dangerous voltage levels are present within the UPS. The UPS should be opened only by service personnel that are qualified. The UPS must be grounded properly to earth. The battery that is supplied with the UPS contains small amounts of toxic materials.

In order to avoid accidents, the following precautions must be observed:

Never operate the UPS if the ambient temperature and relative humidity are higher than the levels that are specified in the documentation.
Never burn the battery. The battery may explode if the battery is burned.
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.
After power is removed, wait for 5 minutes before the UPS is opened. This action allows the capacitors to discharge.
There is high leakage current. The ground conductor must be connected first.
The product must be installed on a surface that is not flammable such as concrete.
The battery must be replaced only by qualified personnel.

Safety of Equipment

Circuit breakers must be installed in order to protect the UPS. A breaker must be installed upstream of the UPS and downstream of the UPS. The breakers must be easy to access in an emergency.
Never install the UPS near liquids or in a damp environment.
Never permit a liquid or a foreign body to penetrate the inside of the UPS.
Never block the grates that are ventilating the UPS.
Never expose the UPS to direct sunlight or to a source of heat.
When the cells in the battery are replaced, use the same type of cells and the same number of cells.

Precautions

The instructions for connecting the UPS that are contained in this manual must be followed in the order that is indicated.
Ensure that the specifications that are on the rating plate correspond to the AC power system.
Ensure that the specifications that are on the rating plate correspond to the total power consumption of all of the equipment that will be connected to the UPS.
If the UPS must be stored prior to installation, the storage area must be dry.
The UPS must be stored in an area that is 35° ± 10°C (95° ± 18°F).
Energize the UPS on a monthly basis for at least 24 hours when the UPS is stored for extended periods. This action charges the battery. If this action is not performed, the battery may be damaged beyond repair.

The UPS is designed for normal operating conditions of altitude, ambient operating temperature, relative humidity, and ambient transport and storage. The UPS will operate correctly under normal conditions, but the battery may fail. The maximum storage time of the UPS is limited due to the need to recharge the integrated battery.

The following operating conditions may justify special measures of design or protection:

Smoke, dust, or abrasive dust
Humidity, vapor, salt air, bad weather, or dripping
Dust and gas mixture that is explosive
Extreme temperature variations
Improper ventilation
Conductive heat or radiant heat from other sources
Cooling water that contains acid or impurities that could cause scale, silt, electrolysis, or corrosion of the parts that are exposed to the water
Strong electromagnetic fields
Levels of radiation that are higher than the natural environment
Fungus, insects, or rodents
Operating conditions of the battery

Additional Safety Rules and Special Precautions

The Isolation of the UPS from upstream power sources must be possible through the use of an isolation device (disconnection device, disconnection circuit breaker) accordingly to local regulations. The disconnection device must be easily accessible.
An emergency switching (disconnect) device preventing any further supply to the load in any mode of operation, must be installed and will cut the upstream supplies of the UPS.

A battery can present a risk of electrical shock and high short-circuit current. The following precautions should be observed when working on batteries:

Remove watches, rings, or other metal objects.
Use tools with insulated handles.
Wear rubber gloves and boots.
Do not lay tools or metal parts on top of batteries.
Disconnect the charging source prior to connecting or disconnecting battery terminals.
Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground. 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).

A label must indicate the existence of multiple supplies at each disconnect device and give adequate instructions for the removal of all power from the unit.
