PowerWalker VI CW Series
I. Setup Requirements
1. Leave sufficient space around for air circulation (recommended 10cm in front, 30cm
in the back and 30cm on sides)
2. Keep ambient temperature below 40ºC. Between 40-50ºC the UPS will gradually
derate the maximal Power reaching 70% at maximal 50ºC.
3. Install the UPS at maximum altitude of 1000m. Between 1000-5000m the UPS will
gradually derate the maximal Power reaching 65% at 5000m.

VI. Button operation
ON/Mute Button
• Press and hold ON/Mute button for at least 2 seconds to turn on the UPS.
• When the UPS is on battery mode, press and hold this button for at least 3 seconds to
disable or enable the alarm system. But it’s not applied to the situations when warnings
or errors occur.
• Press this button to display previous selection in UPS setting mode (up key)
• Press and hold ON/Mute button for 3 seconds to enter UPS self-testing while in AC
mode, ECO mode, or converter mode.
OFF/Enter Button
• Press and hold this button at least 2 seconds to turn off the UPS. UPS will be in standby
mode under power normal or transfer to “Bypass” mode if the “Bypass enabled” setting
is activated.
• Press this button to confirm selection in UPS setting mode.
Select Button
• Press this button to change the LCD message for input voltage, input frequency, battery
voltage, output voltage and output frequency.
• Press and hold this button for 3 seconds to enter UPS setting mode when UPS is in
standby mode or “bypass” mode.
• Press this button to display next selection in UPS setting mode. (down key)
ON/Mute + Select Button
• When the input power is normal, press the two buttons simultaneously for 3 seconds.
Then UPS will enter to the „bypass” mode. This action will be ineffective when the input
voltage is out of acceptable range.
• In setting mode, press the two buttons simultaneously for 0.2s to exit the setting mode.
