Replacing the battery
The battery can be replaced while the unit is stopped (power supply output stopped).
Refer to "10-3 Battery life" of the UPS unit manual (BU150R) for the details about the life of
the battery.
Caution
Replace the battery of this unit and UPS at the same time.
You cannot replace the battery of this unit only.
When the UPS is used in compliance with UL standards, do not
replace the battery while in operation
(while power is being output). Replacing the battery while in
operation does not comply with UL standards. Replace the
battery while the UPS operation is stopped.
Caution (for battery replacement)
Risk of explosion if battery is replaced by an incorrect type.
When replacing batteries replace with the same type and
number of batteries or battery packs.
Notes
Be sure to reset the battery life counter after replacing the battery.
Press and hold the "Buzzer Pause/Test" switch of the UPS for 10 seconds or longer to
reset the battery life counter. Resetting is complete when "bJ" is displayed.
* Reset the battery life counter with the "AC input" plug connected.
・
Stopping ("Power" switch OFF): When the beeper becomes a sustained beep, release
the switch.
・
In Commercial Power Mode ("Power" switch ON): When the beeper changes from
intermittent beeps to a sustained beep, release the switch.
If you do not reset the battery life counter, a battery deterioration alarm may occur
faster than the expected battery life.
When the unit is used in compliance with UL standards, battery replacement should be
performed or supervised by personnel familiar with the danger of batteries and the
required precautions.
If an input power supply error such as a power failure occurs when replacing the battery
while in operation, backup cannot be performed and output stops.
Do not replace the battery while the UPS is operating in backup mode. Output will stop.
Write the battery replacement date in the attached battery replacement date sticker
provided with the replacement battery pack, and attach the sticker to the UPS.
* We are collecting replaced and unneeded batteries at no cost provided that the costs
of shipment to us are borne by the customers. For details, see the attachment "
Guidance for replace service " provided with the replacement battery pack.
