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.
