* If you do not use the UPS monitoring software and Contact Signal, this step is not required.
(5) When the installation and connection is complete, connect the AC Input Plug of the UPS to a wall outlet
(commercial power).
Wall outlet for 3 pins
Wall outlet for 2 pins
Connect it to the Grounding
Terminal of the wall outlet.
● The UPS has been charged prior to shipment. However, the backup time becomes shorter when
using it for the first time due to spontaneous discharge.
We recommend charging the UPS before using it.
When you connect the AC Input Plug of the UPS to a wall outlet (commercial power), charging the
battery is automatically started and it is fully charged for 8 hours or less.
● You can perform "2-4 Checking the operation" on page 17 also before charging the battery.
Grounding Terminal
Use the Grounding Terminal
for grounding connection as
necessary (for example,
when the AC plug does not
provide any grounding
means).
