Up to 10 optional battery modules (5 connected to each battery connector) can be connected
to the EPS2/EPS5 to provide a dc source when the ac supply is not available.
The battery modules must be connected in series using the supplied plugs and cables.
 The battery modules will only operate when the one or both battery circuit breakers are fitted
(see details on page 15) and switched on.
 The weight of the battery modules must be fully supported by either fixed side rails or battery
shelves. These are not supplied with the battery modules.
For specifications see details on page 60. For purchasing information see Spare Parts on page
66.
For information on how to calculate the required number of battery modules see Battery
Module Selection on page 64.
Low Voltage Disconnect (option)
If fitted, the Low Voltage Disconnect (LVD) will disconnect all battery modules at the end of
the battery runtime. This is to prevent damage from deep discharge which may shorten the
battery service life.
An audible click will be heard when the LVD operates or releases (whether or not battery
modules are connected). This is normal.
For further information refer to Low Voltage Disconnect (LVD) in the System Controller
Operation Handbook (see Related Information on page i).

Warnings
This section contains important warnings. Read these warnings before installing or operating
a Powerware Enterprise Power Solutions dc power system.
I
Electrical Safety
• The case of the Powerware Enterprise Power Solutions dc power system is a fire enclosure as
specified in UL 60950-1. The system can be installed in an enclosed cabinet or an open relay rack.
• The dc power system may be powered from multiple ac sources. All power sources must be
isolated before internally servicing the equipment.
• The dc power system must be connected to a suitable and readily accessible disconnect
device(s). The ac plug may be suitable as the disconnect device. See details on page 14.
• The dc power system is not compatible with IT (Impedance Terra) ac supply. For advice see
Worldwide Support on page 73.
• A registered electrician (or suitably qualified person) must check the integrity of the installed
cabling, BEFORE the dc power system is powered up.
• Tasks must be performed in the sequence documented in this guide.

Location and Environment
• The EPS2/EPS5 must be installed in a Restricted Access Location (dedicated equipment rooms,
equipment closets, or similar) in accordance with the U.S. National Electric Code (NEC),
ANSI/NFPA No. 70, and according to the applicable local codes.
• The EPS2/EPS5 is not suitable for use in a computer room as defined in the Standard for
Protection of Electronic Computer/Data Processing Equipment, ANSI/NFPA 75.
Ne peut être utilisé dans une salle d'ordinateurs telle que définie dans la norme ANSI/NFPA 75 Standard
for Protection of Information Technology Equipment.
• For ease of access and to maintain optimum system cooling observe the clearances stated on
page 18.
• Ensure the ambient temperature and humidity are within the ranges in the Specifications.
• Dust build-up within the EPS2/EPS5 may cause premature failure. In dusty environments filter
the ventilation air entering the equipment room. Ensure regular cleaning of the air filters.
• Do not allow water or any foreign object to enter the EPS2/EPS5. Do not place objects containing
liquid on top of or near the unit.

Hazardous Energy Levels
• Rectifiers and batteries contain hazardous energy levels. Only personnel trained and
experienced in dc power systems are to service this equipment.
• Always use insulated tools.
• Do not short-circuit the live and common bus bars or cables.

Rectifiers
• Do not install the rectifiers until the room has been cleaned and is dust free.
• To reduce the risk of electric shock and maintain optimum system cooling, always cover empty
rectifier slots with blanking panels.
• To avoid electrical shock, do not place hands inside the rectifier magazine.
• Rectifier cases may exceed 100ºC (212ºF), especially after prolonged operation. Use suitable
gloves when removing a rectifier from the magazine.
• Do not attempt to disassemble faulty rectifiers. Return them (in their original packaging) with a
completed Equipment Incident Report on page 71.


Servicing
• The dc power system contains hazardous voltages and hazardous energy levels. Do not attempt
to disassemble or service the unit if you are not qualified.

EMC Compliance
• This Powerware product ("the equipment") has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the Federal Communications Commission
(FCC) Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation.
• The equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions in this installation guide, may cause harmful
interference to radio communications. However, there is no guarantee that the interference will
not occur in a particular installation.
• If the equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
• Changes or modifications to the equipment not approved by Eaton Corporation could void the
FCC authority to operate the equipment.

Telecom Ground and dc Supply Bond to Chassis
• CAUTION: This equipment has a connection between the earthed conductor of the dc supply
circuit and the earthing conductor.
Cet appareil comporte une connexion entre le conducteur relié à la terre du circuit d'alimentation c.c. et
son conducteur de terre.

conductor or to a bonding jumper from an earthing terminal bar or bus to which the dc
supply system earthing electrode conductor is connected.
• This equipment shall be located in the same immediate area (such as adjacent cabinets) as
any other equipment that has a connection between the earthed conductor of the same dc
supply circuit and the earthing conductor, and also the point of earthing of the dc system.
The dc system shall not be earthed elsewhere.
• The dc supply source shall be located within the same premises as this equipment.
• Switching or disconnecting devices shall not be in the earthed circuit conductor between the
dc source and the point of the connection of the earthing electrode conductor.

ou à une tresse de mise à la masse reliée à une barre omnibus de terre laquelle est raccordée à l'électrode de
terre du circuit d'alimentation c.c. Les appareils dont les conducteurs de terre respectifs sont raccordés au
conducteur de terre du même circuit d'alimentation c.c. doivent être installés à proximité les uns des
autres (p.ex., dans des armoires adjacentes) et à proximité de la prise de terre du circuit d'alimentation c.c.
Le circuit d'alimentation c.c. ne doit comporter aucune autre prise de terre. La source d'alimentation du
circuit c.c. doit être située dans la même pièce que le matériel. Il ne doit y avoir aucun dispositif de
commutation ou de sectionnement entre le point de raccordement au conducteur de la source
d'alimentation c.c. et le point de raccordement à la prise de terre.
