Omron POWLI BU50XS Instruction Manual page 9

Charge the battery (for at least 8 hours) immediately after purchasing the product.
● If you do not use the product for a long time after purchase, the characteristics of the battery may deteriorate
and become unavailable.
● When you connect the AC Input Plug of the UPS to a wall outlet (commercial power), the battery is automati-
cally charged.
If you store the UPS, charge the battery for at least 8 hours before storage.
● Even if you do not use the battery, it discharges spontaneously and goes into over discharge status if it is left
for a log time. The backup time may become shorter or the battery may become unavailable.
● The storable period of the built-in battery of the UPS is 6 months after charging it for at least 8 hours.
● If you want to store the battery longer than 6 months, connect the AC Input Plug of the UPS to a wall outlet for
at least 8 hours before the limit is exceeded.
● Press the Stop Switch of the UPS to stop it during storage.
Do not reverse the connection of Line/Hub Side and Modem/TA/PC Side of the Network
Line Surge Protection.
● If a failure of the protection circuit occurs, the line side (telephone/ISDN line) may be damaged.
Do not short the output lines of the UPS each other and the output lines to the ground.
● The UPS may fail.
Do not connect the AC Input Plug of the UPS to its Power Supply Output Receptacle.
● The UPS may fail.
Before cutting out commercial power by turning off the breaker or disconnecting the
AC Input Plug, stop the UPS.
If you cannot stop the UPS, it is recommended to automatically stop it in the minimum
backup time using the UPS monitoring software.
● When you stop commercial power, the battery mode starts. If you repeat charging and discharging in a way
in which you stop commercial power and discharge the battery completely, the life of the battery decreases
extremely.
The less the amount of charging and discharging is, the less the effect on the lift becomes.
Do not connect a page printer to the UPS.
● The connection capacity may be exceeded repeatedly during operation using commercial power, which
may cause the status in which the input voltage is outputted directly (bypass mode).
● The peak current of the page printer is large and it may be detected that the connection capacity is ex-
ceeded.
Do not perform a withstand voltage test.
● The input circuit of UPS has a built-in surge absorption device. A withstand voltage test may break it.
● When performing an insulation resistance test, use the 250 VDC range.
