Occasionally, wipe off dust on the input terminal block
and the output terminal block with a dry cloth.
• Accumulated dust may cause a fire.
• Before wiping off dust, stop all connected devices and
the unit, and stop the supply of commercial power.
Do not use the unit in a closed place and do not cover the
unit.
• Doing so may cause abnormal heating or a fire.
If you notice something unusual such as abnormal sound
or smell, discoloration, deformation, and heating, turn
OFF the unit's "Power" switch to stop the output and stop
the supply from the "input power supply".
• Using the unit under such conditions may cause an
abnormal heating, rupture or fire.
• If this situation arises, be sure to stop using the UPS
and request our sales personnel for inspection and
repair.
• A readily accessible disconnect device shall be
incorporated external to the equipment.
If fluid leaks from the interior, do not touch the fluid.
• Doing so may cause blindness or burns.
• If the fluid contacts your eyes or skin, wash it out with
lots of clean water and consult your doctor. The fluid
may damage your eye if your eye is left untreated.
Do not place any objects on the unit, and do not drop
heavy objects onto the unit.
• Doing so may cause distortion/damage to the case or
a failure of the internal circuit, which may cause a fire.
The unit is equipped with a bypass circuit which is able to
supply electric power to connected devices even when
the inner control circuit is broken down by defects or
malfunctions.
If you want to stop the output, stop the source of the "input
power supply".
• Output is continuing even when all indicators of the
front panel are off.
• Output ON/OFF cannot be controlled with the "Power"
