Important Safety Information
Read the instructions carefully to become familiar with the equipment before trying to install, operate,
service or maintain it. The following special messages may appear throughout this manual or on the
equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a
procedure.
The addition of this symbol to a Danger or Warning safety label indicates that an electrical hazard
exists which will result in personal injury if the instructions are not followed.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all
safety messages that follow this symbol to avoid possible injury or death.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, can result in minor or
moderate injury.
CAUTION
CAUTION addresses practices not related to physical injury including certain environmental
hazards, potential damage or loss of data.
Safety and General Information
• Adhere to all national and local electrical codes.
• All wiring must be performed by a qualified electrician.
• Changes and modifications to this unit not expressly approved by APC could void the warranty.
• This UPS is intended for indoor use only.
• Do not operate this UPS in direct sunlight, in contact with fluids, or where there is excessive dust or
humidity.
• Be sure the air vents on the UPS are not blocked. Allow adequate space for proper ventilation.
• For a UPS with a factory installed power cord, connect the UPS power cable directly to a wall outlet.
Do not use surge protectors or extension cords.
• 230 V models only: In order to maintain compliance with the EMC directive for products sold in
Europe, output cords attached to the UPS must not exceed 10 meters in length.
• Leakage current for a pluggable Type A UPS may exceed 3.5 mA when a separate ground terminal is
used.
• The protective earth conductor for the UPS carries the leakage current from the load devices
(computer equipment). An insulated ground conductor is to be installed as part of the branch circuit
that supplies the UPS. The conductor must have the same size and insulation material as the grounded
and ungrounded branch circuit supply conductors. The conductor will be green and with or without a
yellow stripe.
• The ground conductor must be grounded to earth at the service equipment, or if supplied by a
separately derived system, at the supply transformer or motor generator set.
• The battery typically lasts for two to five years. Environmental factors impact battery life. Elevated
ambient temperatures, poor quality utility power, and frequent short duration discharges will shorten
battery life.
• The equipment is heavy. Always practice safe lifting techniques adequate for the weight of the
equipment.
• The batteries are heavy. Remove the batteries before installing the UPS and XLBP in a rack.
• Always install XLBPs at the bottom in rack-mount configuration. The UPS must be installed above
the XLBPs.
• Always install peripheral equipment above the UPS in rack-mount configuration.
• The UPS will recognize as many as 10 external battery packs connected to the UPS. However there is
no limit to the number of XLBPs that can be used with the UPS.
• The model and serial numbers are located on a small, rear panel label. For some models, an additional
label is located on the chassis under the front bezel.
• Always recycle used batteries.
• Recycle the package materials or save them for reuse.

Deenergizing safety
The UPS contains internal batteries and may present a shock hazard even when disconnected from the
branch circuit (mains). Before installing or servicing the equipment, verify that the internal batteries are
disconnected, that external extended run batteries are disconnected and the branch circuit (mains) is turned
off.
Electrical safety
• Connection to the branch circuit (mains) must be performed by a qualified electrician.
• The protective earth conductor for the UPS carries the leakage current from the load devices
(computer equipment). An insulated ground conductor is to be installed as part of the branch circuit
that supplies the UPS. The conductor must have the same size and insulation material as the grounded
and ungrounded branch circuit supply conductors. The conductor will typically be green and with or
without a yellow stripe.
• The grounding conductor is to be grounded to earth at the service equipment, or if supplied by a
separately derived system, at the supply transformer or motor generator set.
• 230 V models only: In order to maintain compliance with the EMC directive for products sold in
Europe, output cords attached to the UPS should not exceed 10 meters in length.
• Leakage current for a pluggable Type A UPS may exceed 3.5 mA when a separate ground terminal is
used.
Battery safety
• Before installing or replacing the batteries, remove jewelry such as wristwatches and rings. High short
circuit current through conductive materials could cause severe burns.
• Do not dispose of batteries by burning them. The batteries may explode.
• Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes, and may be
toxic.
Hardwire safety
• Verify that all branch circuit (mains) and low voltage (control) circuits are deenergized, and locked
out before installing cables or making connections, whether in the junction box or to the UPS.
• Wiring by a qualified electrician is required.
• Check national and local codes before wiring.
• Strain relief is required for all hardwiring.
• All openings allowing access to UPS hardwiring terminals must be covered. Failure to do so may
result in personal injury or equipment damage.
• Select wire size and connectors according to national and local codes.
