This UPS contains no user serviceable parts except the internal battery
pack. The UPS ON/Standby push buttons do not electrically isolate inter-
nal parts. Under no circumstances attempt to gain access internally other
than to replace the batteries due to risk of electric shock or burn. Do not
continue to use the UPS if the front panel indications are not in accor-
dance with these operating instructions or if the UPS performance alters
in use. Refer all faults to your local dealer, Liebert representative or the
Liebert Worldwide Support Group.
Servicing of batteries should be performed or supervised by personnel
knowledgeable of batteries and the required precautions. Keep unautho-
rized personnel away from the batteries. PROPER DISPOSAL OF BAT-
TERIES IS REQUIRED. REFER TO YOUR LOCAL LAWS AND
REGULATIONS FOR BATTERY DISPOSAL REQUIREMENTS.
Never block or insert any object into the ventilation holes or other open-
ings of the UPS.
DO NOT CONNECT equipment that could overload the UPS or demand
half-wave rectification from the UPS, for example: electric drills, vacuum
cleaners, laser printers or hairdryers.
Storing magnetic media on top of the UPS may result in data loss or cor-
ruption.
Turn the UPS off and isolate the UPS before cleaning; use only a soft
cloth, never liquid or aerosol cleaners. Keep the front and rear vents free
of dust accumulation that could restrict airflow.
