S8BA-series Uninterruptible Power Supply (UPS) User’s Manual (U726)

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 com-
mercial power.
The unit will stop after 30 seconds of setting the mode selection/backup operation time
selection switch to "0.5".
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, deforma-
tion, and heating, turn OFF the unit's power and stop the supply from the input power sup-
ply.
To make an emergency stop, turn the rotary switch to "BATT REP" and turn off the input
power after the LED changes from fast blinking to slow blinking.
• Using the unit under such conditions may cause an abnormal heating, rupture or fire.
• If you notice such a condition, stop using the unit and contact our sales personnel for

inspection and repairs.

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 an output circuit that can supply power to the connected devices
even if the unit stops due to a failure or mis-operation of the internal circuit function.
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.
When charging the battery, if the battery cannot be charged completely even after the pre-
determined charging time, turn OFF the "Power" switch of the unit to stop charging the bat-
tery.
The unit will stop after 30 seconds of setting the mode selection/backup operation time
selection switch to "0.5".
• Otherwise, it may cause an abnormal heating, smoke, rupture or fire on the battery.

When performing maintenance of the connected equipment, turn OFF the unit's power and
stop the supply from the input power supply.
The unit will stop after 30 seconds of setting the mode selection/backup operation time
selection switch to "0.5".
• Even if the input power supply is stopped in the operating state, the power supply output

of the unit will not stop, and power will be supplied from the battery.

Do not disassemble, repair, or modify the unit.
• Doing so may cause an electric shock or a fire.

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.
