Safety Precautions
3
1. Relocation, Transportation, and Moving Precautions
CAUTION
Be careful to avoid falling or dropping the UPS during relocation and transportation. It may cause injury.
Place the UPS horizontally during relocation or transportation, and protect the UPS so that not subjected to impact or
strong physical shock. Damage of the batteries may result in an electric shock or fire.
Be careful to avoid back strain when handling the UPS.
To avoid bodily injury or a malfunction caused by dropping the UPS, do not tilt the UPS more than 10 degrees to either
side when moving it vertically. Take preventative measures to avoid dropping the UPS if it must be tilted more than
10 degrees when moving it.
2. Installation Precautions
CAUTION
Request a service technician to install the UPS. Improper installation may result in electric shock, bodily
injury, and/or fire.
Never operate or store the UPS in the following environmental conditions.
Doing so may cause the UPS to malfunction, sustain damage, or deteriorate, which could result in a fire
or other accidents.
a. In ambient environmental conditions other than those specified in the product brochure and
instruction manual
(temperature 0 to 40°C (32 to 104°F), relative humidity 20 to 90%), such as in an extremely high
or low temperature and high humidity
b. Where the UPS is exposed to direct sunlight.
c. Where the UPS is directly exposed to the heat from a heat source, such as a stove.
d. Where grounding is not possible
e. Where the UPS may be subject to vibration or physical shock
f. Near a device that may emit sparks
g. In the presence of dust, salt or corrosive or flammable gas.
h. Outdoors
i. On a poorly ventilated rack (when the UPS is rack mounted.)
Do not block the air intake and exhaust vents of the UPS.
Keep the front of the UPS at least 20 cm and the back is at least 15 cm away from a wall or other object.
If you mount the UPS on a rack, mount it on a rack that can be well ventilated, and do not block the air
intake and exhaust vents of the rack and UPS. If the air intake or exhaust vent is blocked, the internal
temperature of the UPS rises, which could cause battery or other deterioration, resulting in a fire. For
maintenance, the UPS requires at least 1 m of space at the front, and at least 50 cm at the back.
The area around the UPS must be ventilated. The ventilation airflow is 13 m
3
/h.
Unless the specified ventilation airflow is maintained, the gas produced by the battery during charging
could result in case rupture or explosion.
Install the UPS in a location capable of bearing the UPS weight as specified in this manual.
For the weight of the UPS, refer to the table in "§5.1 UPS." If the UPS is installed incorrectly, the UPS may fall,
resulting in bodily injury. Be careful to avoid back strain when handling the UPS.
Move packaging such as plastic bags and film and accessories such as screws to a place that is out of reach of children.
For example, if a child places film over his or her head or swallows a screw, there is danger of suffocation.
3. Wiring Precautions
CAUTION
Request a service technician to wire the UPS.
Incorrect wiring may result in electric shock and/or fire.
Protection for primary circuits against over currents, short circuits, and earth faults is not provided
inside this UPS.
Protection in primary circuit against over currents, short circuits, and earth faults shall be provided as
part of the building installation.
Connect the grounding cable securely in the manner specified (input/output terminal block).
This UPS requires class D grounding work. Failure to connect the grounding cable may result in electric
shock.
Ask a qualified electrician to perform any grounding work that may be required. (A fee will be charged.)
The grounding cables of all load devices* connected to the output of the UPS must be securely connected
to the grounding terminals.
Failure to connect the grounding cables of the load devices correctly may result in electric shock.
*Load devices are devices such as computers connected to the UPS.
