SAFETY INSTRUCTIONS
Safety of persons
• The system has its own power source (the battery). Consequently, the power outlets may be ener-
gized even if the systems is disconnected from the AC power source. Dangerous voltage levels are
present within the system. It should be opened exclusively by qualied service personnel.
• The system must be properly grounded.
• The battery supplied with the system contains small amounts of toxic materials.
To avoid accidents, the directives listed below must be observed:
- 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 re. The batteries may explode.
- Batteries constitute a danger (electrical shock, burns). The short-circuit current may 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 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 the manual must be followed in
the indicated order.
• CAUTION - To reduce the risk of re, the unit connects only to a circuit provided with branch circuit
overcurrent protection for : 30A rating, for 9PX3K3U models in accordance with the National
Electric Code, ANSI/NFPA 70.
The upstream circuit breaker must be easily accessible.
The unit can be disconnected from AC power source by opening this circuit breaker.
• Disconnection and overcurrent protection devices shall be provided by others for permanently
connected AC input/output circuits.
• Check that the indications on the rating plate correspond to your AC powered system and
to the actual electrical consumption of all the equipment to be connected to the system.
• For PLUGGABLE EQUIPMENT, the socket-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 -15ºC to +50ºC.
• The system is not for use in a computer room AS DEFINED IN the standard for the Protection
of Information Technology Equipment, ANSI/NFPA 75.
Contact Eaton resellers to order a special battery kit, if needed to meet the ANSI/NFPA 75
requirement.
Page 4 9PX3K3U_EN
SAFETY INSTRUCTIONS
Special precautions
• The unit is heavy: wear safety shoes and use vacuum lifter preferentially for handling operations.
• All handling operations will require at least two people (unpacking, lifting, installation in rack sys-
tem).
• Straps are provided only for unpacking manually the unit from the carton; don’t use the straps to
carry the unit around. The unit can slip from the straps during handling (risk of injury and product
damage):
- keep 12in / 30cm minimum distance between the straps
- lift the unit carefully and keep it at low height
- keep the unit horizontal during unpacking.
• Before and after the installation, if the UPS remains de-energized for a long period, the UPS must
be energized for a period of 24 hours, at least once every 6 months (for a normal storage tempera-
ture less than 25°C). This charges the battery, thus avoiding possible irreversible damage.
• During the replacement of the Battery Module, it is imperative to use the same type and number of
element as the original Battery Module provided with the UPS to maintain an identical level of
performance and safety. In case of doubt, don’t hesitate to contact your EATON representative.
• All repairs and service should be performed by AUTHORIZED SERVICE PERSONNEL ONLY.
There are NO USER SERVICEABLE PARTS inside the UPS.

10. Glossary
Bypass AC source Source supplying the bypass line. The equipment can be transferred to the
bypass line if an overload occurs on the UPS output, for maintenance or in
the event of a malfunction.
Frequency converter Operating mode used to convert the AC-power frequency between the UPS input
and output (50Hz -> 60Hz or 60Hz -> 50Hz).
Low-battery warning This is a battery-voltage level indicating that battery power is low and that
the user must take action to prevent the imminent break in the supply of power
to the load.
Backup time Time during which the load can be supplied by the UPS operating on battery
power.
Load Devices or equipment connected to the UPS output.
HE mode Operating mode by which the load is supplied directly by the AC source if it is
within the tolerances dened by the user. This mode reduces the consumption
of electrical power
Manual bypass Rotary switch controlled by the user, used to connect the loads directly to the
AC source. Transfer of the load to the manual bypass enables UPS maintenance
without interrupting the supply of power to the connected loads.
Normal (double The normal UPS operating mode in which the AC source supplies the UPS which
conversion) mode in turn supplies the connected loads (after electronic double conversion).
Normal AC source Normal source of power for the UPS.
Relay contacts Contacts supplying information to the user in the form of signals.
UPS Uninterruptible Power Supply.
