1. Important Safety Instructions

WARNING!

Before using the Inverter, read and save the safety
instructions.

1-1. General Safety Precautions

1-1-1. Do not expose the Inverter to rain, snow, spray, bilge or dust.

To reduce 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 and electronic 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

1-1-3. There are some components in the inverter that can cause arcs and

sparks.
To prevent from fire or explosion, do not put batteries, flammable
materials, or anything that is not ignition–protected around the inverter.

1-2. Precautions When Working with Batteries

1-2-1. If battery acid contacts skin or clothing, you should wash it out with

soap and water immediately. If battery acid contacts your eyes, you
should wash it out with cold running water for at least 20 minutes and
get medical attention immediately.

1-2-2. Never smoke or create

a spark or f

lame 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 on the battery of other electrical part may cause an
explosion.

1-2-4. Remove personal metal items such as rings, bracelets, necklaces,

and watches when operating with a lead-acid batteries.
Doing so may cause short circuit and very high temperature, which can
melt metal items and even burn you.

3.4. Installation

The power inverter should be installed in an environment that meets the
following requirements

3-4-1. Dry – Do not allow water to drip on or enter into the inverter.

3-4-2. Cool – Ambient air temperature should be between 0℃ and 40℃, the

3-4-3. Safe – Do not install the inverter in a battery compartment or other

3-4-4. Ventilated –Keep the inverter a distance (as least 1 inch) away from

3-4-5. Dust – Do not install the Inverter in a dusty environments

3-4-6. Close to batteries – Avoid excessive cable lengths. Do not install the

cooler the better.

areas where flammable fumes may exist, such as fuel storage areas or
engine compartments.

surrounding things. Ensure the ventilation shafts on the rear and the
bottom of the unit are not obstructed.

The dust can be inhaled into the unit when the cooling fan is working.

Inverter in the same compartment as batteries.
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. 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.

11

3-5. DC Wiring Connections

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. 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 longer and narrower the cables,
the greater the voltage drop.

Increasing DC cable size helps improve the situation. SAMLEX AMERICA
INC. recommends the following cables for optimum inverter performance.

Model No Wire AWG Inline Fuse

SA-2000K-112 # 2/0 250 A

SA-2000K-124 # 1/0 125 A

3-5-1. Connect the cables to the power input terminals on the rear panel of

the inverter. The red terminal is represents positive (+) and black
terminal represents negative (-). Insert the cables into the terminals
and tighten the screw to clamp the wires securely.

WARNING!

Ensure all the DC connections are tight (torque to
9 – 10 ft-lbs, 11.7 – 13 Nm). Loose connections may
cause overheat and fire.

12

WARNING!

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.

Also, use only high quality copper wire and keep cable length short, a
maximum of 3 - 6 feet.

3-6. 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. Neutral Grounding (GFCI’S):

3-6-1-1. 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.

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 GF

CI.

Samlex America Inc. has tested the following GFCI – protected 20A
receptacles and found that they functioned properly when connected to the
output of the Inverter.

15

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
your loads. If several loads are to be used, turn them on separately after the
inverter is “ON” in order to prevent activation of Over Load Protection “OLP”
due to combined starting surge power.

3-7-1. Set the power switch to “ON” position and the buzzer will send out

“Beep” sounds at the moment. Then the inverter will make self­diagnosis, and the LED’s indicators will change various colors. Finally
the buzzer will “Beep” again and the Input Level and Status LED
indicators will turn to “Green” color, then the inverter starts to work
successfully.

3-7-2. Set the power switch to the OFF position, 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 45 BECKMAN 4410 or TRIPLETT 4200 must be used.

5. 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. At the same time, tighten the screws on the DC
input terminals.
