4. Operating Precautions
WARNING
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.
Do not open the cover of the UPS. Do not detach the cover of the optional connecting area on the back of the
UPS except when you are connecting optional devices. There is danger of electric shock or other accidents.
PROHIBITED
Never use the UPS in applications such as the following:
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 or SANYO DENKI 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 present.
Do not smoke or use an open flame near the UPS. Doing so 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.
Bodily injury may occur if the UPS falls.
Do not operate the switches with wet hands. There is danger of electric shock.
Do not modify, disassemble, or repair the UPS. There are high voltage sections inside the UPS. Opening the UPS
cover, replacing the battery, and repair can result in electric shock or other accidents when performed by anyone other
than service technicians. Such action will void the warranty.
CAUTION
Check the safety of the load side before starting the UPS, and operate the UPS in accordance with the instruction
manual. The UPS state resulting from operating the
MAIN MCCB
or
ON/OFF
button is as shown in the table below.
Check the display and do not touch the
MAIN MCCB
or
ON/OFF
button unless necessary. If power is supplied
incorrectly, 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 thunder occurs 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 service technicians.
Electric shock, bodily injury, burns, fuming, or fire may otherwise result.
Contact your sales representative or SANYO DENKI for UPS repair or defective part replacement.
Opening the cover can result in an electric shock or burn.
Replace the batteries periodically (every 4.5 years at 25°C).
Using batteries after their service life has expired may cause a fire.
Never use organic solvents such as gasoline, thinner, or benzene, or commercial detergents to clean the batteries.
These can cause the casing to crack and leak, resulting in electric leakage or fire.
Do not insert metal objects or fingers into the battery connectors or battery pack 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.
Do not replace Fuse of the inverter module.
