Omron POWLI BU50XS Instruction Manual page 7

Do not connect equipment that exceeds the output capacity of the UPS.
You can use a plug strip and so on to connect extra equipment, but, in this
case, do not connect equipment that exceeds the current capacity of the
plug strip.
● The UPS may detect overload and stop the output.
● The wiring of the plug strip heats up, which may cause a fire.
If the input plug is disconnected while the product is operating, never
touch its metal part.
● Doing so may cause an electric shock.
● The leak current of this product itself is less than the value of the safety standard (leak current:
1 mA). However, leak current increases due to connected equipment. Therefore, never touch
the metal part of the input plug.
● When the product is operating, voltage is generated at the metal part of the input plug via
capacitors in the internal circuit regardless of elapsed time.
If the Battery Replacement Lamp goes on or the backup time becomes
shorter than the required time, immediately replace the battery pack or
stop using the UPS and discard the battery pack.
● Continuing the use of it may cause a fire.
● For information on how to inspect the battery, refer to "6. Maintenance and inspection" on
page 29.

If you notice abnormal sound or smell, smoke, or liquid from the inside,
immediately press the Stop Switch of the UPS and disconnect the AC
Input Plug from a wall outlet (commercial power).
● Using the product under these conditions may cause a leak or fire.
● If you notice such a condition, never use the product and contact the shop from which you
purchased this product or our company for inspection and repair.
● Use the product under the conditions in which you can immediately disconnect the AC Input
Plug from a wall outlet (commercial power) in the event of the occurrence of an abnormal
condition.
When maintaining connected equipment, stop the UPS and disconnect
the AC Input Plug from a wall outlet (commercial power).
● Even if you disconnect the AC Input Plug while the UPS is operating, supplying power is
continued from the Power Supply Output Receptacles by the backup function.
● If the scheduled operation is enabled, supplying power is started when the operation start
time is reached with the AC Input Plug connected to a wall outlet (commercial power).
