Omron POWLI BU100XR2 Instruction Manual page 9

Charge the battery (for at least 8 hours) immediately after purchasing the UPS.
● If you do not use your UPS for a long time after purchasing, the battery characteristic may deteriorate and
become unusable.
● After putting the AC Input Plug of the UPS in a wall outlet (commercial power), the battery is automatically
charged.
When you want to store the UPS, charge the battery for at least 8 hours.
● In a case where you do not use the battery, it discharges spontaneously and gets into over discharge status
after it is left for a long time. The backup time may become shorter or the battery may become unusable
● The expiration date of the battery installed in the UPS is 6 months after charging it for at least 8 hours.
● If you want to store the battery longer than 6 months, put the AC Input Plug of the UPS in a wall outlet
(commercial power) for at least 8 hours before the expiration date is exceeded.
● Press the stop switch of the UPS for storage.
Do not reverse the connection of Line/Hub Side and Modem/TA/PC Side of the Network
Line Surge Protection.
● If a protection circuit failure occurs, the line side (telephone/ISDN line) may be damaged.
Do not give a short between the output lines of the UPS, as well as a
ground fault between the output lines and the ground.
● The UPS may fail.
Do not put the AC Input Plug of the UPS in the Power Supply Output Receptacle of
the UPS.
● The UPS may fail.
Turn off the UPS before opening a circuit breaker or removing the AC Input Plug
from a wall outlet (commercial power).
If you cannot stop the UPS for some reason, bring the UPS to automatic stop through
the UPS monitoring software, which requires the least backup time.
● You can start the backup mode of the UPS simply by cutting off commercial power to the UPS and keep
devices running until the battery gets discharged. That way when you repeat charges and discharges
many times, the life expectancy of a battery pack becomes extremely short.
The less you repeat charges and discharges, the longer the life expectancy of the battery will become.
Do not connect a page printer to the UPS.
● In a case a page printer is connected to the UPS, the amount of output current often exceeds the current
output capacity of the UPS in the commercial power operating mode, and that may lead to the UPS to put
out a feed power as it is (bypass mode).
● The peak current of the page printer is large so that it may be detected as an overcurrent.
Do not perform a withstand voltage test.
● The power input circuit has a built-in surge absorber element. A withstand voltage test may break it.
● When performing an insulation resistance test, select the 250 VDC range.
