6. Radio Frequency Interference
CAUTION
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and if not installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in the residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own expense.
7. Battery Handling Precautions
CAUTION
Battery servicing and checking should be performed only by service technicians. Keep unqualified personnel away
from batteries.
Replace batteries only with the same model and brand as the ones used for this UPS. There is risk of explosion if the
batteries are replaced by an incorrect type.
Do not dispose of used batteries yourself. To dispose of used batteries, contact your nearest sales representative, a
service company, or a business office. The batteries in this UPS are lead type batteries. Lead type batteries are
recyclable resources. Please recycle when replacing or disposing of used batteries.
Do not use batteries after their service life has expired. Doing so may result in fuming or fire. Additionally, the battery
backup function may fail to operate with such batteries, resulting in failure to supply power to load devices when a
power outage occurs.
Batteries pose hazards for electrical shock and dangerous short-circuit current. The following precautions should be
observed when servicing or checking batteries.
a.
Remove watches, rings, and other metal objects.
b.
Use insulated tools.
c.
Wear rubber gloves and boots.
d.
Do not lay tools or metal parts on top of batteries.
e.
Disconnect the charging source prior to connecting or disconnecting battery terminals.
Do not attempt to open or cut batteries. The battery contains diluted sulfuric acid. The sulfuric acid is extremely toxic
and harmful to the skin and eyes. If a battery leaks, take appropriate measures to prevent any battery fluid from
contacting your skin or clothing. Diluted sulfuric acid may cause blindness if it gets into the eye, and may burn skin
upon contact. Additionally, it is electrically conductive and corrosive. Observe the following precautions:
a.
Wear full eye protection and protective clothing.
b.
If sulfuric acid contacts the skin, wash it off immediately with water.
c.
If sulfuric acid contacts the eyes, flush thoroughly and immediately with water, and seek medical attention.
d.
Spilled sulfuric acid should be washed down with a suitable acid-neutralizing agent, such as a solution of
approximately one pound (500 grams) of bicarbonate of soda in one gallon (4 liters) of water. The resulting
liquid should be flushed with water and the area dried.
Lead-acid batteries can present a risk of fire due to the generation of hydrogen gas. Observe the following precautions:
a.
DO NOT SMOKE near batteries.
b.
DO NOT allow flames or sparks near batteries.
c.
Before working with batteries, discharge static electricity.
If a fire occurs near a battery, do not use water to extinguish it. Use only a powder-extinguishing agent (ABC). Using
water may cause the fire to spread.
Do not dispose of batteries in fire. The batteries may explode.
It may cause battery leakage, overheating or explosion. Observe the following precautions:
a.
Do not solder to any part of a battery directly.
b.
Do not charge the batteries with reversed positive (+) and negative (-) terminal polarity.
c.
Do not mix different battery types, brands, or versions.
d.
Do not attempt to peel off or break the outer covering of a battery.
e.
Do not subject batteries to strong physical shock, or throw them away.
f.
Do not use organic solutions such as gasoline, thinner, or benzene, or detergent to clean the batteries.
g.
Electrical energy may remain in a battery even after its service life has expired. Do not allow sparks near used
batteries.
