Setting the Nominal Voltage
Before
the UPS is connected to utility power, select the appropriate voltage via the voltage selection
switch, located on the rear panel. This will enable the UPS to start with the proper output voltage.
The
3000XLV
UPS is able to output 100, 110, 120 and 127V; and the
3000XHV
is able to output 200,
208, 220, 230 and 240V. To ensure that the UPS output is centered at or near a voltage that the user
requires, set this selection switch appropriately. (Default voltages are pictured below.)
If this is not done
before
UPS startup, turn off the UPS, set voltage and restart. Loads connected be-
forehand might not have optimal voltage.

While operating on battery, the output voltage equals that of the actual voltage setting dialed. While
operating online, the output voltage is regulated to a range around the nominal voltage. The upper
and lower limits of this range can be user-configured through PowerChute. The input voltage range
can vary while the UPS regulates output without going to battery, and is wider than the regulated
output voltage because of the UPS regulating transformer.
Startup
1. Connect equipment to the UPS.
Note: A laser printer draws significantly more power than other types of equipment and
may overload the UPS.
2. Using the supplied power cord, plug the UPS into a two-pole, three-wire, grounded receptacle
only. Avoid using extension cords.
Upon utility power outlet connection, the UPS will auto-
matically turn on.
3000XLV
: The power cord is permanently attached to the rear panel of the UPS. The input plug
is a NEMA L5-30P.
3000XHV:
The supplied power cord plugs into the rear panel of the UPS.
3.
3000XLV
: Check the
site wiring fault
LED
located on the rear panel. It will be illuminated if
the UPS is plugged into an improperly wired utility power outlet (See
Troubleshooting
).
4. Turn on all connected equipment. To use the UPS as a master
on/off
switch, be sure all con-
nected equipment is turned on.
5. For optimal computer system security, install PowerChute monitoring software onto all com-
puters powered by the UPS.
