5-2 Replacing the battery
This UPS supports hot swapping. Battery replacement is possible both when the power is
turned OFF (while the power output is OFF) and when the power is turned ON (while the
power output is ON).
Notes
▪
For battery replacement, hold down the “Beep Stop/Test” switch on the unit for 10
seconds or longer to activate the battery replacement mode. Resetting is complete
when “
”
is displayed.
* Perform a reset with the “input power supply” ON.
If you replace the battery without activating the battery replacement mode, the
battery life may not be detected accurately because the battery life counter is not
reset.
▪
Do not replace the battery while the UPS is operating in backup mode. Output will
stop.
Reference
▪
If an input power supply error such as a power failure occurs when replacing the
battery while in operation, backup cannot be performed and output stops.
▪
When the battery replacement LED lights “ ” up/blinks and beeper sounds, press
the “Beep Stop/Test” switch for 0.5 seconds to stop the beeper. (Lighting/blinking of
the battery replacement LED lights “
” does not disappear.)
