Default Setting Available Settings Description
Output frequency [50Hz] [60Hz] [Auto sensing]
NOTE Numerical settings configured in Standby mode take effect
immediately. Auto sensing and settings configured outside of
Standby mode take effect after the next power off and restart.
Selecting auto sensing disables the battery start feature until the
first successful startup on utility power.
For 9910-E35 and 9910-E36 models, the default auto sensing runs
once to set the output frequency and then uses the detected
setting for all subsequent startups.
For 9910-E66 and 9910-E67 models, the default auto sensing runs at
each startup to set the output frequency.
Auto sensing
NOTE When configured
for auto sensing, the
UPS uses the optimal
detected setting for
frequency.
Overload alarm level [10%] [20%] [30%]...[100%]
If 100%, the UPS issues an Output Overload alarm at load >100%.
NOTE Configure the Output Overload Level 1 to alert you before
the UPS reaches its rated capacity limits.

Bypass voltage low
limit [-6%] [-7%]...[-20%] of nominal
The Bypass operation is disabled if the measured bypass voltage
level is below the nominal output voltage (-15%).
NOTE The Qualify Bypass setting might overrule the Bypass
Voltage Low Limit setting.

Bypass voltage high
limit [+6%] [+7%]...[+20%] of nominal
The Bypass operation is disabled if the measured bypass voltage
level is above the nominal output voltage (+10%).
NOTE The Qualify Bypass setting might overrule the Bypass
Voltage High Limit setting.
