●
The UPS has been charged prior to shipment. However, the backup time becomes shorter
when using it for the
fi
rst time due to spontaneous discharge.
We recommend charging the UPS before using it.
When the AC input plug is connected to a wall outlet (commercial power), the battery au-
tomatically starts charging, taking up to 8 hours to complete (24 hours when an additional
battery unit is connected).
●
You can perform "2-4 Checking the operation" on page 17 also before charging the bat-
tery.
• When using a 2-pin input plug with a grounding wire, connect the grounding wire to earth in
building.
• When you want to use an AC adaptor, connect it to a Power Supply Output Receptacle of the
UPS with space enough for the connection.
Note 1: This connection cannot be performed when this product is used in compliance with UL stan-
dards.
(3) If you use the included UPS monitoring software or the standard UPS service of
Windows NT or Windows XP/2000 or if you use Contact Signal, connect the con-
necting cable between the UPS and your PC.
