WORKING LED
Please verify if you have chosen the right operating voltage for both input and
output.
Connect the red cable from the "+" terminal (red terminal) of the battery to
the + binding post (red connection) of the converter and the black cable from
the "-" terminal (black terminal) of the battery to the "-" binding post (black
connection) of the converter.
Be sure to tighten the screws in order to avoid loose connection.
WARNING: DO NOT REVERSE INPUT AND OUTPUT

5. OUTPUT CAPACITY
The converter will switch off automatically if the total wattage of the electrical
appliances exceed the converter's output capacity. This will also happen if the
temperature of the converter exceeds 65℃ +/-10% due to prolonged use.

4. OPERATION
A) When connected to an appliance, remember to turn on the converter before
turning on the appliance. If the buzzer sounds during operation, this indicates
that the battery voltage is very low and the converter will be disconnected
in 5 minutes.
B)
that the rating power of the appliance is not exceed the rating power of the
converter.
When connecting an electrical appliance to the converter, please make sure

6. ADDING EXTENSION CORD
We recommend that the buyer refrain from using an extension cord between the
DC power source and the converter's DC input. Connecting an extension cord to
the DC input will create a voltage drop, entailing reduced efficiency and output.
7. VENTILATION
IMPORTANT! During operation, make sure the fan keeps revolving. Check the
possible malfunctions if the fan does not work when this unit is
being used. Make sure the fan is not blocked in order to avoid poor ventilation.
8. CAUTION
In case of trouble with the DC output, e.g.short-circuit, overload, etc... the
protection circuit will automatically cut off the output.
In such cases:
(A) switch off the power at once
(B) disconnect all units
(C) check the connected devices
(D) use the units again unless the problems
concerning the connected devices have been solved
When in use for a prolonged period of time, the DC output may suddenly be cut
off although the battery voltage is still very strong. This may be caused by
excessive temperatures.
If this happens. Please proceed as follows:
(A) Switch off the converter at once
(B) Disconnect some of the appliances or wait until the converter cools off
(C) Switch the inverter back on
Always keep the converter in an environment which is:
(A) Well-ventilated
(B) Not exposed to direct sunlight or any other heat source
(C) Inaccessible to children
(D) Safe from water/moisture, oil or grease
(E) Safe from any flammable substance

9. MAINTENANCE
Very little maintenance is required to keep your converter operating properly.
You should clean the exterior of the unit periodically with a damp cloth to
prevent accumulation of dust and dirt. At the same time, tighten the screws on
the DC input and DC output terminals.
10. NOTE
All specifications typical at nominal line, half load, and 25℃ unless otherwise
noted.
Specifications subject to change without notice.
WARNING: DO NOT DISASSEMBLE THE UNIT. HAZARDOUS VOLTAGE!
DANGER!
PLEASE RETURN TO THE DEALER IF YOU FIND ANY PROBLEM WITH
THE UNIT.
11. SUITABLE POWER SOURCE
5
In order to operate the converter and supply power to an appliance, a suitable
24V DC power supply is required. This can be a vehicle or caravan battery,
portable power pack or an independent 24V lead acid battery, For most
applications, a deep cycle battery is recommended for best performance..
The size of the battery used will determine how long the converter will supply
power to an appliance and how well the converter will perform. Most batteries
are marked with their size in Amp hours (AH) or Cold Cranking Amps.
Because converter are capable of drawing high currents, the converter should
only be connected to a suitable size battery, Connection to an undersized
battery could damage the battery and will result in the converter shutting down
within a short period due to low battery voltage.
The amount of power dawn from the battery is proportional to the converter
load.
