Important Safety InstructionsSAVE THESE INSTRUCTIONS
This manual contains instructions and warnings that should be followed during the installation,
operation and storage of this product. Failure to heed these warnings will void your warranty.

UPS Location Warnings

• Install the UPS indoors, away from excess moisture, temperature extremes, conductive contaminants,
dust and direct sunlight.
• For best performance, keep the indoor temperature between 32º F and 104º F (0º C and 40º C).
• Leave adequate space around all sides of the UPS for proper ventilation.
• Do not mount the unit with its front or rear panel facing down (at any angle). Mounting in this
manner will seriously inhibit the unit’s internal cooling, eventually causing product damage not
covered under warranty.

UPS Connection Warnings

• Connect the UPS to a properly grounded AC power outlet. Do not plug the UPS into itself; this will
damage the UPS.
• Do not modify the UPS input connector, and do not use an adapter that would eliminate the ground
connection of the UPS.
• Do not use extension cords to connect the UPS to an AC outlet.
• If the UPS receives power from a motor-powered AC generator, the generator must provide clean,
fi ltered, computer-grade output.

Equipment Connection Warnings

• Use of this equipment in life support applications where failure of this equipment can reasonably
be expected to cause the failure of the life support equipment or to signifi cantly affect its safety
or effectiveness is not recommended. Do not use this equipment in the presence of a fl ammable
anesthetic mixture with air, oxygen or nitrous oxide.
• Do not connect surge suppressors to the output of the UPS. This might damage the UPS and will
void the surge suppressor and UPS warranties.

Battery Warnings

• The UPS does not require routine maintenance. There are no user-serviceable parts inside. Do not
open the UPS for any reason.
• Batteries present a risk of electrical shock and burns from high short-circuit current. Battery
replacement should be performed only by authorized service personnel. Observe proper precautions.
Unplug and turn off the UPS before performing battery replacement. Use tools with insulated
handles. Replace the existing batteries with the same number and type of batteries (sealed Lead-
Acid). Do not open the batteries. Do not short or bridge the battery terminals with any object.
