receptacle on the front panel of the inverter.
Leave the test load switch off.
G-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 measure the true output r.m.s. Voltage of inverter, the
meter such as FLUKE 45 BACKMAN
4410 or TRIPLETT 4200 must be used.
H. Installation:
H-1. Where to install
The power inverter should be installed in a location that meets
the following requirements:
H-1-1. Dry – Do not allow water to drip or splash on the inverter.
H-1-2. Col – Ambient air temperature should be between 0°C and
40°C, the cooler the better.
H-1-3. Safe – Do not install in a battery compartment or other
areas where flammable fumes may exist, such
as fuel storage are as or engine compartments.
H-1-4. Ventilated – Allow at least one inch of clearance around the
inverter for air flow. Ensure the ventilation
openings on the rear and bottom of the unit are
not obstructed.
-8-
H-1-5. Dust-free –Do not install the Inverter in a dusty environment
where either dust, wood particles or other
filings/shavings are present. These can pulled
into the unit when the cooling fan is operating.
H-1-6. Close to battery/batteries –
Avoid excessive cable lengths but do not install
the Inverter in the same compartment as
batteries. Use the recommended wire lengths
and sizes (see section 7.3). Also 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.
H-2. 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 connect
to the incoming ground from your AC utility
source.
The AC output ground wire should go to the
grounding point for
your loads ( for example, a distribution panel
ground bus ).
H-2-1. Neutral Grounding
H-2-1-1.
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 AC sources (such as inverter and
generators) have their neutral conductors tied to
ground in the same way that the neutral conductor
-9-
from the utility is tied to ground at the AC breaker
panel. For models configured with a transfer relay,
when AC utility power is present and the Inverter is
in bypass mode, this connection (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.
H-2-1-2.
230V models: There is no connection made inside the Inverter from
either of the line conductors (line or neutral) to the
safety ground.
Ground Fault Circuit Interrupters (GFCI’S):
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
Inverter. In addition, electrical codes require GFCI protection of
certain receptacles in residential installations. While the true 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’s. State power has tested the
following GFCI-protected 15A receptacles and found that they
functioned properly when connected to the output of the Inverter.
Do not operate the power inverter without
connecting it to ground.
Electrical shock hazard may result.
WARNING!
H-3. Making DC Wiring Connections :
Follow this procedure to connect the battery cables to the DC
-10-
input terminals on the Inverter. Your cables should be as short
as possible (ideally, less than 10 feet / 3 meters) and large
enough to handle the required current, in accordance with the
electrical codes or regulations applicable to your installation.
Cables that are not an adequate gauge (too narrow) or are too
long will Cause decreased inverter performance such as poor
surge capability and frequent low input voltage warnings and
shutdowns.
These low input voltage warning is due to DC voltage drop
across the cables from the inverter to the batteries. The linger
and narrower these cables, the greater the voltage drop.
I. Operation:
To operate the power inverter, turn it on using the ON/OFF switch
on the front panel. The power inverter is now ready to deliver AC
power to your loads. If you are operating several loads from the
power inverter, turn them on separately after the inverter has been
turned on. This will ensure that the power inverter does not have to
deliver the starting currents for all the loads at once.
I-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 from:
10 to 16 VDC for 12V models
20 to 32 VDC for 24V models
42 to 62 VDC for 48V models
Peak performance for these inverter occurs when DC input
voltage is in the Range of 10 volts to 16 volts for 12V models and
20 volts to 32 volts for 24V Models, and 42 volts to 62 volts for
-11-
48V models. From 600Watts up to 3000Watts.
I-2. Battery voltage indicator :
The battery voltage bar graph indicates the voltage at the input
terminals of the power inverter at low input current, this voltage is
very close to the battery voltage. At high input current, this voltage
will be lower than the battery voltage because of the voltage drop
across the cable and connections. Ideally, the voltage should
remain in the green Ares of the bar graph. If the voltage goes into
the red area at top and bottom of the graph, inverter may shut –
down.
I-3. Load watt indicator
The AC load watt bar graph indicates the power drawn from the
power inverter. It will indicate watt by loads. For long term
operation , the watt should in the green & orange area of the bar
graph. Short-term operation is possible with watt in the red area. If
the watt rises to the flash all bar, the inverter will protect itself.
I-4. Over voltage indicator :
The over voltage indicator indicates that the power inverter has
shut itself Down because its input voltage has been over detect
voltage 12 / 24V / 48VDC version.
I-5. Under voltage indicator :
The under voltage indicator indicates that the power inverter has
shut itself Down because its input voltage has been low than
detect voltage 12 / 24V / 48VDC.
-12-
I-6. Over temp indicator :
The over temp indicator indicates that the power inverter has shut
itself down because it has become overheated. The power
inverter may overheat because it has been operated at power
levels above its rating, or because it has been installed in a
location which does not allow it to dissipate heat properly. The
power inverter will restart automatically once it has cooled off.
I-7. Overload indicator :
The overload indicator indicates that the power inverter has shut
itself down Because its output circuit has been short circuited or
drastically overloaded.
Switch the ON/OFF switch to OFF, correct the fault condition, and
then switch the ON/OFF switch back to ON.
J. Operating limits:
J-1. Power output:
The inverter will operate most AC loads within its power rating.
When deeming whether a microwave over can be operated by
the inverter, remember that the power commonly advertised for
microwave ovens is the cooking power (the power delivered to
the food) not the power actually consumed by the microwave
oven. The microwave over will consume 40% to 100% more than
its advertised cooking power. Check the rating sticker on the
back of the over to determine its actual power draw.
The Power inverter may not be able to start some of this motor
even though their rated current draw is within the power inverter.
If motor refuse to start, observe the battery voltage indicator while
trying to Start the motor. If the battery voltage indicator drops
below 11 volts while inverter is attempting to start the motor, this
may be why the motor won’t start. Make sure that the battery
connections are good and that the battery is fully charged. If the
-13-
connections are good and the battery is charged, but the
voltage still drops below 11 volts, you may need to use a larger
battery.
K. Trouble shooting:
K-1. Common problems Television interference :
Operation of the power inverter can interfere with television
reception on Some channels. If this situation occurs, the
following steps may help to alleviate the problem.
Make sure that the chassis ground lug on the back of the
power inverter is solidly connected to the ground system of
your vehicle, boat or home.
Do not operate high power loads with the power inverter
while watching television.
Make sure that the antenna feeding your television provides
an adequate (“Snow free”) signal and that you are using
good quality cable between the antenna and the television.
Move the television as far away from the power inverter as
possible.
Keep the cables between the battery and the power inverter
as short as possible and twist them together with about 2 to
3 twists per foot.
This minimizes radiated interference from the cables.
K-2. Troubleshooting guide:
Do not open or disassemble Inverter, attempting to service
WARNING!
the unit yourself may result in a risk of electrical shock
or fire.
