Failure to do so may result in a fire.
To avoid electric shock, do not open the cover of the UPS. Do not detach the cover of the options, except when
you use some options. There is danger of electric shock or other accidents.
Never use the UPS for the following types of loads :
a. Medical instruments used for life support.
b. Control units for trains or elevators, failure of which may cause bodily injury.
c. Computer systems upon which social or public infrastructure depends.
d. Devices which serve applications related to the above.
Contact your sales representative if you need to use the UPS in an application like the above. Special equipment such
as redundant devices or an emergency generator must be incorporated when operating, maintaining and controlling
systems in which a UPS is used with loads affecting life-support or public infrastructure-dependent applications.
This UPS must be installed, operated and maintained by technically qualified personnel in an industrial
environment. This UPS should not be used in any other environment; for example, a general home environment
where a technically qualified personnel is not in.
Do not smoke or use an open flame near the UPS, as it could cause the UPS to explode or rupture, resulting in injury
or fire.
Do not place containers of liquid, such as a flower vase, on the UPS. If the container was to spill, the liquid could
cause a short circuit, resulting in sparks or fire inside the UPS.
Do not sit, ride, step or lean on the UPS, as bodily injury could result if the UPS was to fall.
Do not operate the switches with wet hands. There is danger of electric shock.
All repairs and modifications to the UPS are prohibited. The UPS contains high voltage and no user serviceable parts.
Opening the cover, exchanging the battery, parts exchange, and repair can result in electric shock or other accidents
when performed by anyone other than qualified service personnel. All such repairs and modifications will void the
warranty.

5. Maintenance and Inspection Precautions
Maintenance and repair of the inside of the UPS should be performed only by technically qualified personnel.
Electric shock, bodily injury, burns, fuming, or fire may otherwise result.
Contact your nearest sales representative or authorized service center to have the UPS checked out or to
replace defective parts. Opening the cover carelessly can result in an electric shock or burn.
Replace the batteries periodically (once every 4.5 years when operated at 25 C (77 F)). Using batteries after
their service life has expired may cause a fire.
Never use organic solvents such as gasoline, thinner, benzene or detergents to clean batteries. These can
cause the casing to crack and leak, resulting in electric leakage or fire.
Do not allow metal objects or fingers to touch the battery connectors of the UPS. Doing so may result in an
electric shock or burn.
Do not touch any parts inside the UPS, even when the AC input is removed and the batteries are removed.
There is the danger of electric shock from high voltage that remains in parts.
