1. Important Safety Information
WARNING!
Before installing and using the Inverter, you need to read
following safety information carefully.
1-1. General Safety Precautions
1-1-1. Do not expose the Inverter to water, mist, snow, or dust. To reduce the
risk of hazard, do not cover or obstruct the ventilation shaft.
Do not install the Inverter in a zero-clearance compartment.
Overheating may occur.
1-1-2. To avoid the risk of fire and electronic shock, make sure that existing
wiring is in good electrical condition and not undersize.
Do not operate the Inverter with damaged or substandard Wiring.
1-1-3. There are some components in the inverter can cause arcs and sparks.
To prevent from fire or explosion, do not put batteries, flammable
materials, or anything should be ignition–protected around the inverter.
1-2. Precautions When Working with Batteries
1-2-1. If battery acid contacts your skin or clothing, you need to wash it out
immediately with soap and water. If acid enters into your eyes,
immediately flush your eyes with running cold water for at least 20
minutes and get medical attention immediately.
1-2-2. Never smoke or make a spark or flame in the vicinity of batteries or
Engines.
1-2-3. Do not drop a metal tools on the battery. The resulting spark or short-
circuit on the battery or other electrical parts may cause an explosion.
1-2-4. Remove personal metal items such as rings, bracelets, necklaces, and
watches when working with a lead-acid battery,
A lead-acid battery may produce a short-circuit current who’s
temperature is high enough to weld these metal items and cause a
severe burn.

3. Instructions
SA-150 and SA-300 series are very reliable, portable, and fully protected. These
pure sine inverters are used in a wide range of applications such as mobiles,
office equipments, home entertainment, electronic appliances, etc.
To get the most effective power inverter, it must be installed and used properly.
Please read the instructions of this manual before you install and operate this
model.
3-1. Front Panel Operations
3-1-1. ON / OFF REMOTE switch：
Leave the switch in the down position (OFF) during installation.
3-1-2. LED display indicates Power Status
LED Conditions Status
Solid Green AC Power OK
Fast Red Blink OVP
Slow Red Blink UVP
Intermittently Red Blink OTP
Solid Red OLP
3-1-3. Remote Port：Place 0.75mm2and Screw type cable between the
remote port and the panel.
3-2. Rear Panel Operations
3-2-1. Ventilation shaft：Keep the ventilation shaft a distance (at least 3 inch)
from anything surrounding it
3-2.2. Input terminals：Connect the input terminal to 12V / 24V battery or
other 12V / 24V power source. 【＋】represents
positive, and【－】represents negative. Reverse
polarity connection will blow the internal fuse and may
damage inverter permanently.
3-3-3. Use wire # 8 AWG to connects Chassis ground with Vehicle Chassis.

WARNING！
Do not combine the 12V model with 24V battery or the unit will
be destroyed immediately.
Operate with the inverter without a proper ground connection
may cause an electrical safety hazard.
Damage caused by reversed polarity is not covered by the
warranty. Ensure the power switch is in the OFF position
before putting the battery in.
3-3. AC Safety Grounding：
During AC wiring installation, AC input and output ground wires are
connected to the inverter. The AC input ground wire must be connected to
the incoming ground from AC utility source.
The AC output ground wire should go to the grounding point for your loads
( for example, a distribution panel ground bus ).
3-3-1. Neutral Grounding (GFCI’S):
110V models：The neutral conductor of the AC output circuit of the
Inverter is automatically connected to the safety ground during inverter
operation. This conforms to National Electrical Code requirements that
separately derived from AC sources (such as inverters and generators)
which have their neutral conductors tied to ground in the same way as
the neutral conductors from the utility tied to ground at the AC breaker
panel. For models configured with a transfer relay, while AC utility
power is present and the Inverter is in bypass mode, this connection
(the neutral of the Inverter’s AC output to input safety ground) is not
present so that the utility neutral is only connected to ground at your
breaker panel, as required. Samlex has tested the following GFCI-
properly when connected to the output of the Inverter.
WARNING！
Never connect the inverter’s output to the AC distribution grid,
such as the household AC wall outlet.
It will damage the Inverter.

3-4. Installation
Before connecting your applications to the inverter, always check the power
draw of your appliances. The inverter can supply surge power for a short time
so as to start up the electrical equipment such as motors, pumps… that need
more power while starting up.
When all the above requirements are checked OK and satisfied and all
connections are made, it’s time to turn on the inverter by switchingthe power
to ‘ I ’ position. The sine wave filters provide sine wave output voltage when
driven from AC outlet.
To save the battery power, you are highly recommended to turn off the
inverter when it is not used.
DC input voltage status as follows:
Model DC Input Over

be “OFF”.
3-7-2. Before using the remote unit, make sure the main switch must
be “ REMOTE”.
3-7-3. Ensure the remote control contact is off.

4. Troubleshooting
WARNING！
Do not open or disassemble the Inverter. Attempting to
service the unit yourself may cause the risk of electrical
shock or fire.
Problems and Symptoms Possible Cause Solutions
No output voltage, the LED glows Red light.
a. Power status light is
blinking red fast. Over input voltage. Check input voltage. Reduce input voltage.
b. Power status light is
blinking red slowly. Low input voltage. Recharge battery. Check connections and
cable.
c. Power status light is
blinking red intermittently. Thermal shutdown Improve ventilation. Make sure ventilation
shafts in the inverter are
not obstructed.
Lower ambient
temperature.
d. Power status light is
glowing red steadily. Short circuit, Wiring error, Overload Check AC wiring for short circuit.
Remove load.

5. Maintenance
Very little maintenance is required to keep your inverter operating properly.
You should clean the exterior of the unit periodically with a damp cloth to pre vent
accumulation of dust and dirt. At the same time, tighten the screws on the DC
input terminals.
