transfers between inverter power and shore
power from recreational facilities such as boat
docks or campsites to ensure power is
always available.
Back-up
Capability
If incoming shore power is interrupted by
external events like brownouts, the Freedom
X automatically becomes an independent
power source1that supplies utility grade AC
power to your loads.
1Assuming the inverter is connected to a battery source with an adequate charge at the time of the power
interruption.

Comprehensive
Protection
The Freedom X’s built-in protection features
safeguard your batteries (from unnecessary
drain) such as the low battery voltage alarm
and shutdown and protect equipment such as
a configurable AC transfer speed.
nSelectable Low Battery Shutdown:
The low battery shutdown for the
inverter can be manually selected by the
user from 10.1 to 12.8VDC.
nVoltage Shutdown Delay Timer:
Configurable from 1 to 300s to reduce
an unnecessary shutdown of inverter
operation such as during cranking or
other brief but heavy discharge of
battery.
nInverter Power Save: The Freedom X
can be programmed to automatically
turn off after 1 to 25 hours of continued
operation of loads that are under 50
watts. It is designed, with LBCO (low
battery cut off), to prevent the battery
from deep discharge.
Configurable AC
Transfer Speed
The Freedom X allows two speed settings for
the AC transfer from AC Mode to Battery
Mode and vice versa which avoids nuisance
resetting of appliances. The normal transfer
rate is for common appliances and the faster
transfer rate is designed for more sensitive
digital equipment like a desktop computer.
Overload Alarm
and Shutdown
During Battery Mode (also called Inverter
Mode), the Freedom X automatically alerts
you if the loads that are connected and
drawing power from the unit are close to
approaching the maximum operating limit. If
so, the Freedom X automatically shuts down
when the maximum operating limit is
exceeded. See Troubleshooting Reference on
page 66 for precautions.
Over temperature
Alarm and
Shutdown
During Battery Mode, the Freedom X
automatically alerts you if it is overheating
and approaching the over-temperature
shutdown limit. The Freedom X automatically
shuts down when the limit is exceeded. See
Troubleshooting Reference on page 66 for
precautions.

Ignition Control The Freedom X provides two user-selectable
options for ignition control:
nIgnition Auto-on: The Freedom X can
automatically turn the inverter on and off
in tandem with the vehicle's ignition
circuit or a manually operated remote
switch.
nIgnition Lockout: The Freedom X
features the ability to inhibit the inverter
from operating in the absence of a
voltage signal from a vehicle's ignition
circuit. This is particularly useful if the
inverter is required to operate only when
a vehicle's engine is running.
Configurable AC
Output Frequency
and Voltage
The Freedom X is factory set to 60Hz AC
output frequency and 120V AC output
voltage. It can be configured to 50Hz for use
in regions outside the USA and Canada. The
AC voltage setting can also be configured to
either of three settings: 108, 110, or 120volts.
