Omron BU5002R Instruction Manual page 11

The unit is fitted with a switching circuit that enables electric power to
be supplied to the connected devices directly from the commercial
power supply, in the event that the product is stopped as a result of
breakdown of the internal control circuit function or a malfunction.
Stop the output of the unit after safely stopping the connected devices.
⚫ To stop the output, either stop the commercial electrical power supply, or remove
the AC input plug.
⚫ There is a possibility of electric shock if the output terminal is touched without
stopping the output.
⚫ The output continues even if all the front panel displays are off.
⚫ The output cannot be turned ON/OFF using the front "Power" switch.
The unit has a limited service life. Replace the unit in a planned manner,
and do not use it beyond its service life.
⚫ If the product continues to be used beyond its lifespan, it may cause malfunction or
breakdown, such as failing to perform backup normally or stopping operation
suddenly. In addition, there is a risk of smoke generation and ignition, which may
result in fire.
⚫ The service life of the unit is 7 years when the ambient temperature is 25°C, and 5
years when the ambient temperature is 40°C. However, the lifespan varies
depending on the ambient environment (temperature, dust), so these values are for
guidance and are not guaranteed values.
When performing maintenance on the connected device, turn the
"Power" switch of the unit off to stop the output, and stop the
commercial power supply.
⚫ During operation, power output of the unit does not stop even when the commercial
power supply has stopped, so there is a possibility of electric shock.
When the black "INPUT PROTECTION" button (input overcurrent
protection switch) on the rear of the BU3002R/BU3002RH is protruding,
connected devices are too many, or a short circuit is occurring on a
connected device. Do not press the black button repeatedly or
continuously in such a situation.
⚫ Press the black button after inspecting the connected devices. If the button
protrudes again, stop using the unit, and contact the shop of purchase.
⚫ There is a possibility of smoke generation or ignition if the black button is pressed
repeatedly or continuously.
When using this unit, make sure to attach the output terminal block
cover. In addition, do not turn on the "Power" switch when the cover is
removed.
⚫ If the "Power" switch is turned on, voltage is applied to the output terminal block,
which may cause electric shock.
⚫ When replacing a cable, make sure to fix the cable with a clamp.
