Caution
Replace the battery packs of this unit and the UPS main unit at
the same time.
⚫
Dilute sulfuric acid may leak.
⚫
There is a risk of an electric shock or a short circuit of the battery.
When the UPS main unit is used as a UL standard compliant
product, do not replace the battery while operating (while power
is being output). The battery replacement function does not
comply with UL standards while operating, so be sure to replace
the battery after stopping operation of the UPS main unit.
⚫
To perform replacement while stopped, stop the connection function, turn
off the “Power” switch on the UPS main unit, and remove the “AC input”
plug from the power outlet.
⚫
When an input power error such as power outage occurs during battery
replacement while the unit is operating, the backup process is disabled
and output stops.
⚫
Do not replace the battery during the backup operation. Doing so will stop
the output.
