Chapter 2 Safety Warnings
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that you should follow during installation and
maintenance of the UPS and batteries. Please read all instructions before operating the
equipment and save this manual for future reference.
D A N G E R
This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE
PARTS inside the UPS.
W A R N I N G
S
This UPS contains its own energy source (batteries). The output receptacles may carry
live voltage even when the UPS is not connected to an AC supply.
S
For 220–240V models, the output receptacles may remain electrically live. If the input
power source in your application is wired line-to-neutral (as in most European
applications), the voltage to the output receptacles is 0V. With line-to-line input wiring,
the voltage to the output receptacles is 100–120V (measured from line-to-ground or
line-to-neutral, depending on the UPS wiring).
S
Do not remove or unplug the input cord when the UPS is turned on. This removes the
safety ground from the UPS and the equipment connected to the UPS.
S
To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity
controlled, indoor environment, free of conductive contaminants. Ambient temperature
must not exceed 40
°C (104°F). Do not operate near water or excessive humidity (95%
maximum).
S
To comply with international standards and wiring regulations, the total equipment
connected to the output of this UPS must not have an earth leakage current greater than
1.5 milliamperes.
C A U T I O N
S
The wall outlet must be within 2 meters of the equipment and accessible to the operator.
S
Batteries can present a risk of electrical shock or burn from high short-circuit current. The
following precautions should be observed: 1) Remove watches, rings, or other metal
objects; 2) Use tools with insulated handles; 3) Do not lay tools or metal parts on top of
batteries; 4) Disconnect charging source prior to connecting or disconnecting battery
terminals.
S
Proper disposal of batteries is required. Refer to your local codes for disposal
requirements.
S
Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
S
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the
skin and eyes and may be extremely toxic.
S
Replace batteries with the same number and type of batteries as originally installed in
the UPS.
S
If the UPS requires any type of transportation, disconnect the internal UPS batteries
before transporting (see page 17).
