Safety Precautions
BUM5002R/BUM3002R
12
When the UPS main unit is used as a UL standard compliant product, do
not replace the battery while operating (while power is being output).
The battery replacement function does not comply with UL standards
while operating, so be sure to replace the battery after stopping
operation of the UPS main unit.
⚫To perform replacement while stopped, stop the connection function, turn off the
“Power” switch on the UPS main unit, and remove the “AC input” plug from the
power outlet.
⚫When an input power error such as power outage occurs during battery
replacement while the unit is operating, the backup process is disabled and output
stops.
⚫Do not replace the battery during the backup operation. Doing so will stop the
output.
Notes
After bringing the unit from a cold place to a warm place, leave it for several hours
before starting use.
⚫Condensation may occur if the unit is brought into a warm place suddenly, and if the unit is used in
such condition, there is a risk of breakdown.
After purchasing, charge the battery promptly.
⚫If the battery is not used for a long time after purchasing, the battery properties degrade, and in
some cases it becomes unusable.
⚫The battery can be charged once the expansion battery unit is connected to the UPS main unit,
and the UPS main unit is connected to commercial power.
When the unit is to be stored, charge it for 8 hours or more, and turn off the
overcurrent protection switch. Recharge within 6 months when stored at a storage
temperature of 25°C or less, and within 2 months when the storage temperature is
40°C or less.
⚫Self-discharge occurs even when the battery is not used, and if left for a long period of time, the
battery becomes over discharged. This causes the backup time to be shortened, or the battery to
become unusable.
⚫For long-term storage, it is recommended that the environment is 25°C or lower.
⚫During storage, turn off the overcurrent protection switch of the unit.
Do not install or store the unit in a place where it is subject to direct sunlight.
⚫The internal battery may be rapidly degraded by the temperature rise, and it may become
unusable.
Do not use the unit for frequent backup operation.
⚫The battery will deteriorate and become unable to last for the specified backup time.
