1. Installation Precautions
The UPS should be installed only by technically qualified personnel. Improper installation
•
can 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.
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 30 to 90%), such
as in 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 the UPS may be subject to vibration or physical shock.
e.
Near a device that may emit sparks.
f.
In the presence of dust, salt or corrosive or flammable gas.
g.
Outdoors
Do not allow the air intake or exhaust vents to be obstructed. Keep the front and back of
•
the UPS at least 20 cm(7.88in) away from the wall. If the air intake or exhaust vent is
blocked, the internal temperature of the UPS rises, which could cause battery deterioration
resulting in a fire. During maintenance, the UPS requires at least 1 m (39.4in) space at the
front and 50 cm(19.69in) at the back.
The space around the UPS must be ventilated. Unless the specified ventilation airflow (5
•
m
/h) is maintained, gas produced by battery charging could result in rupture or explosion
3
of the case.
Install the UPS on a stable surface capable of bearing the weight of the UPS in the correct
•
manner specified in this manual.
If the UPS is installed incorrectly, impact or vibration could cause it to fall or move
•
inadvertently, resulting in bodily injury. Be careful to avoid back strain.

2. Wiring Precautions
Wiring should be performed only by technically qualified personnel. Incorrect wiring can
•
result in electric shock and/or fire.
Wire with the specified wire and the specified torque surely.

nd
Connect the grounding cable securely in the manner specified. Failure to connect the
•
grounding cable may result in electric shock.
The grounding cables of all load devices* connected to the output of the UPS must be
•
securely connected to the grounding terminal. Failure to connect the grounding cables
correctly may result in electric shock.
* Load devices are devices such as computers that are connected to the UPS.
