SECTION 1 | Important Safety Instructions
To ensure reliable service, your power
inverter must be installed and used
properly. Please read the installation and
operating instructions thoroughly prior
to installation and use. Pay particular
attention to the WARNING and CAUTION
statements in this manual.
The CAUTION statements advise against
certain conditions and practices that may
result in damage to your inverter. The
WARNING statements identify conditions
or practices that may result in personal
injury. Read All Instructions Before Using
This Power Inverter!
WARNINGS
TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, EXPLOSION OR INJURY
1. Do not connect to AC distribution
wiring.
2. Remove appliance plug from outlet
strip or turn off inverter before working
on the appliance.
Multiple outlet power strips with
switches and circuit breakers interrupt
power only to the “hot” receptacle terminals. The “neutral” terminals remain
powered with respect to the“ground”
terminals.
3. Do not make any electrical connections
or disconnections in areas designatedas
IGNITION PROTECTED. This includes
12 VDC cigarette plug connections, and
terminal connections.
4. This is not a toy - keep away from
children.
5. DO NOT insert objects into air vents.
CAUTIONS
!
1. Do not use with positive ground
electrical systems (the majority of
modern automobiles, RVs, trucks and
boats are negative ground). Reverse
polarity connection will result in a
blown fuse and may cause permanent
damage to the inverter.
2. This inverter will not operate high
wattage appliances over the output
power limit or surge power limit.
3. Grounding the neutral will cause the
inverter to shut down. Do not operate
this inverter if it is wet. Do not install in
engine compartment – please install in
a well ventilated area.
4. This inverter is not tested for use with
medical devices.
IMPORTANT CABLE
INFORMATION
Substantial power loss and reduced battery operating time results from inverters
installed with cables that are not able to
supply full power. Symptoms of low battery power can result from cables that are
either excessively long or an insufcient
gauge. The installer/operator should be
especially aware of the requirements to
maintain SECURE, TIGHT, WATER-RESISTANT electrical connections and to provide
for strain relief for DC cables and appliance wiring. Cable insulation must be the
appropriate type for the environment.

SECTION 3 | Introduction
Your new SAM Series power inverter is one in a series of the most
advanced DC to AC inverters available today. With proper care and
appropriate usage, it will give you years of dependable service in
your car, truck, RV or boat.
SAM Series inverters designed with a
universal protection circuit that provide
added safety features include automatic
shutdown, earth fault protection and a
low battery alarm to prevent damage to
your battery.
This power inverter is congured with the
latest low interference technology (L.I.T.),
Universal Protection Circuit (UP-Circuit)
and Soft Start circuit to improve inverter
operation.
UP-Circuit
Provides full automatic inverter and battery protection. This includes overheat
protection, battery protection, overload
protection, short circuit protection and
earth fault protection.
L.I.T.
Greatly improve the interference problems of common power inverter. Before
introduction of L.I.T., signal interference
may occur on TV pictures, audio system or
radio equipments. Now you can enjoy a
clean and powerful AC source!
Soft Start Circuit
Provides three major features. First,
gradual voltage ramp-up during inverter
start-up. This eliminates failed cold starts
under load. Second, output that momentarily dips in voltage and quickly recovers.
This eliminates most shutdowns from
momentary overloads.
Load Controlled Cooling Fan
The fan will switch on automatically when
the load > 8 to 12W and switch off when
load drops below 8 to 12W.
USB Charging Port
A USB charging port rated at 5V, 500 mA
is provided for charging devices provided
with USB charging facility.
