Set Site Fault
Use the Set Site Fault option to enable or disable the site wiring fault
alarm. The default is disabled. Enable the alarm for installations where a
grounded-neutral electrical system is in place (see “Site Fault Wiring”
on page 57 for more information).
Set Sleep Mode
Use the Sleep Mode feature to control loads that use less than 10% of the
current when the UPS is on battery. The default is disabled.
Enable this option if you do not want a load less than 10% of the current
to be protected by battery power. This feature conserves battery power
by shutting down less critical loads.
