Description
Available settings
Overload alarm level
[10%] [20%] [30%]...[100%]
If 100%, the UPS issues an Output Overload alarm at load >
100%.
Note: Output Overload Level 1 by default is set to 100% and is
configurable from 10% to 100% in 10% increments through the
LCD setting menu. This enables you to be alerted before the
UPS has reached its rated capacity limits.
Automatic start delay
[Off] [0s] [1s] [2s]...[32767s]
See "Configuring load segments" on page 27.

Site wiring fault alarm
[Enabled] [Disabled]
Bypass voltage low
[-6%] [-7%]...[-20%] of nominal
limit
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
[+6%] [+7%]...[+20%] of nominal
limit
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.
Qualify bypass
[Always] [Never] [Bypass Disabled]
If Always, Bypass operation is allowed when:
v Bypass voltages > the value set for Bypass Voltage Low Limit
v Bypass voltages < the value set for Bypass Voltage High Limit
v Bypass frequency > (nominal frequency -3 Hz)
v Bypass frequency < (nominal frequency +3 Hz)
v Inverter is synchronized with Bypass when unsynchronized
If Never, Bypass operation is always allowed, if the utility is within
the UPS operating limits; voltage and frequency limits are not in
use. If Bypass Disabled, Bypass operation is prohibited.
Extended battery

modules (EBMs)
See "Configuring the UPS for an extended battery module" on
page 29.
Battery low alarm
[Immediate] [2 min] [3 min] [5 min]
If you select a value, the battery low alarm is triggered when the
set amount of backup time (approximately) remains in the
batteries.
Automatic battery tests [Enabled] [Disabled]
See "Running automatic battery tests" on page 30.
