3-3. Installation
The power inverter should be installed in an environment that meets the
following requirements
3-3-1. Dry – Do not allow water to drip on or enter into the inverter.
3-3-2. Cool – Ambient air temperature should be between 0℃and 33℃, the
cooler the better.
3-3-3. Safe – 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.
3-3-4. Ventilated – Keep the inverter a distance (at least one inch) away from
surrounding things. Ensure the ventilation shafts on the rear and the
bottom of the unit are not obstructed.
3-3-5. Dust free – Do not install the Inverter in dusty environment.
The dust can be inhaled into the unit when the cooling fan is working.
3-3-6. Close to batteries – Avoid excessive cable lengths. Do not install the
Inverter in the same compartment as batteries.
Use the recommended wire lengths and sizes (see section 3-6).
Do not mount the inverter where it will be exposed to the gases
produced by the battery. These gases are very corrosive, and
prolonged exposure will damage the Inverter.
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.

3-4. Quick hook – up and testing
For a quick hook – up of the power inverter to check its performance
before going ahead with installation, please follow these guidelines
3-4-1. To check its performance, unpack and inspect the power inverter the
switch is OFF.
3-4-2. Connect the cables to the power input terminals on the rear panel of
power inverter. The red terminal represents positive (+) and black
terminal represents negative (-). Insert the cables into the terminals
and clamp the nuts and the wires securely.
WARNING!
You may observe a spark when you make this
connection since current may flow into charge
capacitors in the power inverter.
Do not make this connection with the flammable
fumes close by. Explosion or fire may occur.
WARNING!
Ensure all the DC connections are tight (torque to 9 -
10) ft-lbs, 11.7 – 13 Nm. Loose connections and
overheat may result in a potential hazard.
10

11
3-4-3. Before proceeding further, carefully check that cable you have
connected does tie negative terminal of inverter to the negative output
power source.
3-4-4. Connect the cable from the negative terminal of the inverter to the
negative terminal of the power source. Make a secure connection.
3-4-5. Set the power switch to the “ON” position and the buzzer will send out
beep sound at the moment the inverter will make self-diagnosis and the
LED’s indicators will also appear various colors. Finally the buzzer
will send out another beep sound and the input Level LED indicators
will turn to “Green” color and the inverter starts working successfully.
3-4-6. Set the power switch to OFF position, the inverter stops and all the
lights go Off.
3-4-7. Set power inverter switch to the 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 inverter, a meter
such as FLUKE 45 BECKMAN 4410 or TRIPLETT 4200 must be used.
CAUTION !
Reverse polarity connection will blow the fuse in
inverter and may permanently damage the inverter.
Damage caused by reverse polarity connection is not
covered by warranty.

3-5. AC Safety Grounding
During the 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 ).
3-5-1. Neutral Grounding (GFCI’S)
3-5-1-1. 120V 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.
3-5-1-2. 230V models：There is no connection made inside the
Inverter from either the line or neutral conductor to safety
ground.
WARNING!
The risk of electronic shock. Use only pass and Seymour
type 2091-W, ground fault circuit-interrupter receptacles.
Other types may fail to operate properly when connected to
this inverter equipment.

Ground Fault Circuit Interrupters (GFCI)
Installations in Recreational Vehicles (for North American approvals) will
require GFCI protection of all branch circuit connected to the AC output of
the hardwire terminal equipped with Inverter. In addition, electrical codes
require GFCI protection of certain receptacles in residential installations.
While the pure sine wave output of the Inverter is equivalent to the waveform
provided by utilities, compliance with UL standards requires us to test and
recommend specific GFCI.
Samlex has tested the following GFCI – protected 20A receptacles and found
that they functioned properly when connected to the output of the Inverter.
3-6. DC Wiring Connections：
Follow this procedure to connect the battery cables to the DC input terminals
on 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.
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.
These low input voltage warnings are due to DC voltage drop across the
cables from the inverter to the batteries.
The linger and narrower the cables, the greater the voltage drops.
WARNING!
Do not operate the power inverter without connecting
it to ground. Electrical shock hazard may occur.
WARNING!
The fuse must be installed on 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.

14
Increasing DC cable size helps improve the situation.
Samlex recommends the following cables for optimum inverter performance.
Model No Wire AWG Inline Fuse
SA-600R-112 # 4 100A
SA-600R-124 # 6 50A
Also, use only high quality copper wiring and keep cable length short, (a
maximum of 3-6 feet).

3-7. Inverter Operation
To operate the power inverter, use the ON / OFF switch on the Front panel to
turn the power on. Then the power inverter is ready to deliver AC power to
the loads.
If you are operating several loads from the power inverter, turn them on
separately after the inverter is on.
This will ensure that the power inverter does not have to deliver the starting
currents for all the loads at one time.
3-7-1. Controls and indicators
The ON / OFF switch turns the control circuit in the power inverter on
and off. It does not disconnect power from the power inverter.
The Inverter operates from an input voltage ranging of：
10.5 to 15.0 VDC for 12V models
21.0 to 30.0 VDC for 24V models
The Inverter will indicate high and low DC voltage conditions as
follows：
