Safety

Safety Rules

Safety of Persons

The UPS must be installed in a room with restricted access, accessible only to qualified personnel, according to standard EN50091-1-2. A UPS has its own internal power source (the battery). Consequently, power outlets may be energized 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, observe the following directives:

• 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.
• Avoid contact with the cooling liquid (eyes and skin). If contact occurs, rinse well with water.

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.

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 -10°C to +45°C. If the UPS remains de-energized for a long period, it is recommended to energize the UPS for 24 hours, at least once every month, to charge the battery and avoid possible irreversible damage.

The UPS is designed for normal climatic and environmental operating conditions as defined in the appendices chapter: 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 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, vapor, 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 the 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 HD 384.4.42 S1/A2 - Chapter 42: Protection from thermal effects.
• Standard IEC 60364-4-482 - Chapter 482: Fire protection.
