4. Operating Precautions
DANGER
•
Immediately shut the UPS off if it malfunctions, or if an unusual odor or noise is observed. 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 and equipment damage.
PROHIBITED
•
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 could 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.
•
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, 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 and
damage to the UPS when performed by anyone other than qualified service personnel. All such repairs and
modifications will void the warranty.
CAUTION
•
The following table shows the UPS states resulting from operation of the
MAIN SW
and
ON/OFF
switches.
Check the indicators before and after operating. Do not touch the
MAIN SW
and
ON/OFF
switches unless
necessary. If power is supplied incorrectly, an electric shock or bodily injury could result.
•
Avoid inserting sharp objects or fingers into the fan. Doing so may result in bodily injury.
•
Do not touch the UPS, including the cables, if you hear thunder nearby. There is danger of electric shock from a
lightning strike.
5. Maintenance and Inspection Precautions
CAUTION
•
Maintenance and repair of the inside of the UPS should be performed only by technically qualified personnel.
Electric shock, bodily injury and burns, fuming, or fire could 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
ﾟ
F)).
Using batteries after their service life has expired may cause a fire.
•
Never use organic chemicals such as gasoline, thinner, benzene or detergent to clean batteries.
These can cause the casing to crack and leak, resulting in fire.
•
Do not allow sharp metallic objects or fingers to touch the battery connectors of the UPS. Doing so may result in
an electric shock.
•
Do not touch any parts inside the UPS, even when AC input is removed.
Voltage produced from the batteries can still cause an electric shock.
