This UPS contains no user serviceable parts except the internal bat-
tery pack. The UPS ON/Standby push buttons do not electrically iso-
late internal 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 indi-
cations are not in accordance 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 unau-
thorized personnel away from the batteries. PROPER DISPOSAL OF
BATTERIES 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
openings 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
corruption.
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.
When replacing batteries, replace with the same Liebert authorized
replacement battery kits.
