Personal safety
• The system has an internal battery as a backup power source. Consequently, the power outlets may be
energized even if the system is disconnected from the AC power source.
• Dangerous voltage levels are present within the system. The system should be opened exclusively by
qualifi ed service personnel.
• The system must be properly grounded.
• There are no user servicable parts inside the system, except for the replaceable battery.
• The battery supplied with the system contains small amounts of toxic materials.
• To avoid accidents, observe the following directives:
- Servicing of batteries should be performed or supervised by personnel knowledgeable about batteries
and the required precautions.
- When replacing batteries, replace with the same type and number of batteries or battery packs.
- Do not dispose of batteries in a fi re. The batteries might explode.
- Batteries constitute a danger (electrical shock, burns). The short-circuit current might be very high.
Precautions must be taken for all handling:
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if the 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).
Product safety
• The UPS connection instructions and operation described in this manual must be followed in order.
• A protection circuit breaker must be installed upstream and be easily accessible. The system can be
disconnected from the AC power source by opening this circuit breaker.
• Verify that the indications on the rating plate correspond to your AC powered system and to the actual
electrical consumption of all the equipment connected to the system.
• For pluggable equipment, the outlet shall be installed near the equipment and shall be easily accessible.
• Never install the system near liquids or in an excessively damp environment.
• Never let a foreign body penetrate inside the system.
• Never block the ventilation grates of the system.
• Never expose the system to direct sunlight or source of heat.
• If the system must be stored prior to installation, storage must be in a dry place.
• The admissible storage temperature range is -15°C to +50°C (5°F to 122°F).
• The system is not for use in a computer room as defi ned in the standard for the Protection of
Information Technology Equipment, ANSI/NFPA 75 (US installations only).
Contact Hewlett Packard Enterprise resellers to order a special battery kit, if needed to meet the
ANSI/NFPA 75 requirement.
Special precautions
• All handling operations require at least two people (unpacking, installation in rack system).
• Before and after the installation, if the UPS remains de-energized for a period of more than 6 months,
the UPS must be energized for a period of 24 hours, at least once every 6 months (for a normal storage
temperature less than 25°C/77°F). This charges the battery and avoids possible irreversible damage.
• During the replacement of the battery module, use the same type and number of elements as the
original battery module provided with the UPS to maintain an identical level of performance and safety.
In case of doubt, contact your Hewlett Packard Enterprise representative.
