SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation, operation, and maintenance of your
Liebert® Large UPS Battery System. Read this manual thoroughly, paying special attention to the sections that apply to
your installation, before working with the UPS and battery system. Retain this manual for use by installing personnel.
WARNING! Risk of electrical shock. Can cause personal injury or death. This UPS has several circuits that are
energized with high DC as well as AC voltages. Check for voltage with both AC and DC voltmeters before
working within the UPS. Check for voltage with both AC and DC voltmeters before making contact. Only
properly-trained and qualified personnel wearing appropriate safety headgear, gloves, shoes and glasses
should be involved in installing the equipment or preparing for installation. When performing maintenance
on any part of the equipment under power, service personnel and test equipment should be standing on
rubber mats. In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or
those approved for use in fighting electrical fires.
WARNING! Risk of heavy unit falling over. Improper handling can cause equipment damage, injury or death.
Because the weight distribution in the cabinet is uneven, use extreme care while handling and transporting.
Take extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel. Locate
center of gravity symbols and determine unit weight before handling each cabinet. Test lift and balance the
cabinets before transporting. Maintain minimum tilt from vertical at all times. For weights, see
WARNING! Risk of electrical shock and fire. Can cause equipment damage, personal injury or death. Only
normal safety precautions are necessary under typical operation and with all UPS doors closed. The area
around the UPS system should be kept free of puddles of water, excess moisture and debris. Only test
equipment that is designed for troubleshooting should be used. This is particularly true for oscilloscopes.
Always check with an AC and DC voltmeter to ensure safety before making contact with the UPS or using
tools to work on any UPS component. Dangerously high potential electric charges may exist at the capacitor
banks and at the DC connections even when input power is turned Off. All wiring must be installed by a
properly trained and qualified electrician. All power and control wiring must comply with all applicable
national, state and local codes. One person should never work alone, even if all power is disconnected from
the equipment. A second person should be standing-by to assist and to summon help in case of an accident.
