Safety Warnings
CAUTION: Before performing the procedures in this document, read and follow the safety instructions and
important regulatory information in your Safety, Environmental, and Regulatory Information document.
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that you should follow during installation and
maintenance of the UPS and batteries. Please read all instructions before operating the equipment and
save this manual for future reference.
DANGER:
avoided, will result in death or serious injury:
S This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE
PARTS inside the UPS.
WARNING:
avoided, could result in death or injury:
S This UPS contains its own energy source (batteries). The output receptacles may carry live voltage
even when the UPS is not connected to an AC supply.
S Do not remove or unplug the input cord when the UPS is turned on. This removes the safety
ground from the UPS and the equipment connected to the UPS.
S To reduce the risk of fire, connect only to a circuit provided with branch circuit overcurrent
protection with an ampere rating in accordance with the National Electrical Code
ANSI/NFPA 70 or your local electrical code:
UPS Output Power 120V 208V 230V
2700W 30A 20A 16A
S To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity
controlled, indoor environment, free of conductive contaminants. Ambient temperature must not
exceed 40°C (104°F). Do not operate near water or excessive humidity (95% maximum).
S Unpacking the cabinet in a low-temperature environment may cause condensation to occur in and
on the cabinet. Do not install the cabinet until the inside and outside of the cabinet are absolutely
dry (hazard of electric shock).
S If the UPS requires any type of transportation, disconnect the internal UPS batteries before
transporting (see page 58).

CAUTION: Observe the following instructions to help prevent a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury or in property damage incidents:
S For PLUGABLE EQUIPMENT, the power outlet shall be installed near the equipment and shall
be easily accessible.
S Servicing of batteries should be performed or supervised by personnel knowledgeable about
batteries and the required precautions. Keep unauthorized personnel away from batteries.
S Batteries can present a risk of electrical shock or burn from high short-circuit current. The
following precautions should be observed: 1) Remove watches, rings, or other metal objects; 2) Use
tools with insulated handles; 3) Wear rubber gloves and boots; 4) Do not lay tools or metal parts on
top of batteries; 5) Disconnect the charging source prior to connecting or disconnecting battery
terminals.
S Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the utility
source from the 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).
S ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or connectors.
Attempting to alter wiring can cause injury.
S Replace batteries with the same number and type of batteries as originally installed in the UPS.
S Proper disposal of batteries is required. Refer to your local codes for disposal requirements.
S Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
S Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and
eyes and may be extremely toxic.
S The 2700W UPS may be connected to a maximum of one External Battery Module (EBM).
WARNING:
Additional instructions for Rack-Mounted Systems
S Your rack kit has been approved only for the rack cabinet provided. It is your responsibility to
ensure that installation of the equipment into any other rack complies with all applicable
standards. Dell disclaims all liability and warranties with respect to combinations of equipment
with any other rack.
S Before installing your equipment in a rack, install all front and side stabilizers. Failure to install
stabilizers can allow the rack to tip over.
S Always load from the bottom up, and load the heaviest items first.
S Do not overload the AC power supply branch circuit that provides power to the rack.
S Do not stand or step on any components in the rack.
