Omron BU5002R Instruction Manual page 23

Before installing the unit, take note of the serial number of the unit.
The serial number of the product is necessary when making inquiries to the shop of
purchase.
The product serial number is indicated on the seal on the back of the unit (in the
case of BU3002R, the seal on the top), and on the product serial number seal
included in the packaging. It can be displayed on the LCD panel as well.
This product uses a lead battery (lead accumulator).
⚫ Lead batteries are valuable resources that can be recycled. Please cooperate with
recycling. For recycling the unit, contact the shop of purchase.
Take precautions against unforeseen circumstances, such as by providing data
protection or system redundancy.
⚫ Output from this unit may stop in case of a breakdown in the internal circuit.
The value of the total capacities of the devices connected to the output receptacles
must not exceed the rated output capacity of the BU3002R. If the overload fault
display (E9) appears, reduce the connected devices.
The lead battery used in the unit has a limited service life. The service life varies
depending on your storage/operating environment and backup frequency.
⚫ The nearer the end of service life is, the more rapidly deterioration proceeds.
⚫ For details on the battery life, see the reference document "Battery life" at the end of this manual.
⚫ The battery deteriorates even if it is stored. Note that as the temperature is increased the life
rapidly shortens.
Be sure to reset the battery life counter after replacing the battery.
⚫ After replacing the battery, select [2. Control] - [Reset B. life counter] from the LCD menu of the
unit, and reset the battery life counter.
If the battery life counter is not reset, the battery replacement alarm may be issued before the
expected end of the battery life is reached.
After resetting the battery life counter, record the battery replacement date.
⚫ Write the battery replacement date on the provided battery replacement date label and attach it to
the main unit.
⚫ The battery replacement date can be input from the LCD menu [3. Settings] - [Battery Settings] -
[Battery Installation].
After replacing the battery, execute the self-diagnosis test.
⚫ The self-diagnosis test can be performed manually from the LCD menu of the unit by selecting [2.
Control]-[Start Function Test]. After the self-diagnosis test has been completed, the status
automatically returns to the normal operational status.
When connecting a device that generates a back electromotive force such as a relay
to the signal output circuit, connect a diode to prevent the back electromotive force
on both ends of the relay.
