1. Important Safety Instructions
WARNING!
Before using the inverter, please read and save these safety
instructions.
1-1. General Safety Precautions
1-1-1. Do not expose the inverter to rain, snow, spray, bilge or dust. To reduce the risk of hazard, do
not cover or obstruct the ventilation openings. Do not install the inverter in a zero-clearance
compartment. Overheating may result.
1-1-2. To avoid a risk of fire or electrical shock, make sure that existing wiring is in good electrical
condition and not undersized. Do not operate the inverter with damaged or substandard
wiring.
1-1-3. There are some components in the inverter that can cause arcs and sparks. To prevent fire or
explosion, do not put batteries, flammable materials, or anything that should be ignition–
protected around the inverter.
1-2. Battery Safety Precautions
1-2-1. If battery acid contacts skin or clothing, you need to wash with soap and water immediately.
If battery acid contacts your eyes, you need to wash it out with cold running water for at least
20 minutes and get medical attention immediately.
1-2-2. Never smoke, make a spark or create a flame in the vicinity of the battery or the engine.
1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-circuit of this act may
result in an explosion, spark or fire.
1-2-4. Remove personal metal items such as rings, bracelets, necklaces, and watches when operating
with lead-acid batteries. Failure to do so may result in a spark or short circuit event, which can
result in very high temperatures that can melt the metal items and potentially cause serious
bodily harm.

4. Installation
4-1. General Installation Recommendations
The power inverter should be installed in an environment that meets the following requirements:
(a) Do not allow water to drip on or enter into the inverter.
(b) Ambient air temperature should be between 0°C and 40°C, the cooler the better.
(c) Do not install the inverter in a battery compartment or other areas where flammable fumes may
exist, such as fuel storage areas or engine compartments. These gases are very corrosive, and
prolonged exposure will damage the inverter.
(d) Keep the inverter a distance (as least 1 inch) away from surrounding things. Ensure the
ventilation shafts on the front and rear of the unit are not obstructed.
(e) Do not install the inverter in a dusty environment. The dust can be inhaled into the unit when
the cooling fan is working.
(f) Avoid excessive cable lengths. Use the recommended wire lengths and sizes (see section 3-5).
Do not mount the inverter where it will be exposed to the gases produced by the battery.
WARNING!
Shock hazard; before proceeding further, carefully check that the inverter
is NOT connected to any batteries, and that all wiring is disconnected
from any electrical sources. Do not connect the output terminals of the
inverter to an incoming AC source.

SSI Series Owners Manual

4-2. DC Wiring Connections
4-2-1 Follow this procedure to connect the battery cables to the DC input terminals of the inverter.
The cables should be as short as possible (less than 10 feet / 3 meters ideally) and large
enough to handle the required current in accordance with the electrical codes or regulations
applicable to the installation.
(a) Cables that are not an adequate gauge (too narrow) or too long will deteriorate inverter
performance such as poor surge capability and frequent low-input voltage warnings and
shutdowns.
(b) These low input voltage warnings are due to DC voltage drop across the cables from the
inverter to the batteries.
(c) The longer and narrower the cables, the greater the voltage drop. Increasing DC cable size
helps improve the situation.
(d) Sensata Technologies recommends the following cables for optimum inverter performance:
Model #
Wire AWG
1-10’
Wire AWG
11-15’
Wire AWG
16-20’
Inline Fuse or
Circuit Breakers
SSI-12-HF3.5N
# 8
# 6
# 6
Up to 40 amps
4-2-2 Connect the cables to the power input terminals on the rear panel of the inverter. The red
terminal represents positive POS. [ + ] and black terminal represents negative NEG. [ –].
Insert the cables into the terminals and tighten the screw to clamp the wires securely.
Sensata Technologies recommends using only high quality (SGX) insulated copper wire and
keep the cable length short, a maximum of 3 to 6 feet.
The installation of a fuse must be on a positive cable. Failure to place a fuse on ―+‖ cables running
between the inverter and battery may cause damage to the inverter and will void warranty.

4-4. AC Safety Grounding
The AC output ground wire should go to the grounding point for your loads (for example, a distribution
panel ground bus).
3-6-1. 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.
4-5. Inverter Operation
To operate the power inverter, use the ON / OFF switch on the front panel to turn the power ON. The
power inverter is now ready to deliver AC power to your loads. If there are several loads in use, turn
them on separately after the inverter is ―ON‖ in order to prevent over voltage protection (OVP)
resulting from the surge power.
4-5-1. Set the power switch to ―ON‖ position and the buzzer will send out ―beep‖ sound. Then the
inverter will perform a self-diagnostic, and the LED indicators will also appear various colors.
Finally the buzzer will ―beep‖ again and the Input Level and Status LED indicators will turn to
―green‖ in color, then the inverter starts to work successfully.
3-7-2. Set the power switch to the OFF position, and then the inverter stops and all the lights go off.
3-7-3. Set the power inverter switch to ON position and turn the test load ON. The inverter should
supply power to the load. If you plan to accurately measure the true output R.M.S. voltage of
the inverter, a meter such as FLUKE 87 or better, or any Multi-Meter marked as ―True RMS‖
must be used.

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 / Symptoms
Possible Cause
Solutions
There is no AC power output, and the
status indicator LED is :
a. RED, blinking fast
Over input voltage (OVP)
Check the input voltage, reduce input
voltage
b. RED, blinking slowly
Low input voltage (UVP)
Recharge the battery, check
connections and the cable
c. RED, blinking intermittently
Over Temperature (OTP)
Improve ventilation, make sure
inverter vents are not obstructed,
lower ambient temperature
d. RED, solid ON
Short circuit, overload or wiring
error (OLP)
Check AC wiring for short circuit,
reduce the load

Maintenance
To keep your inverter operating properly, there is very little maintenance required. You should clean the
exterior periodically with a damp cloth to prevent accumulation of dust and dirt; please note to have the
inverter turned OFF and not to allow excessive moisture enter the inverter. At the same time, check
connections and tighten the screws on the DC input terminals if necessary.
