3. 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.
！
CAUTION
•
The space around the UPS must be well ventilated. Otherwise, gas produced by battery
charging could result in rupture or explosion of the case.
•
Before starting the UPS, make sure that the load side is safe. Be sure to refer to the
instruction manual while operating the UPS. The operating state of the UPS, as
determined by the ON/STAND BY switch, is indicated by the LEDs as shown the table
below. Check these indicators when operating.
Be careful when operating the ON/STAND BY switch. 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.
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.
4. 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°F).
Using batteries after their service life has expired may cause a 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.
