Caution
Never use the inverter with positive ground!
Caution
Before connection make sure the inverter is turned off.
4. USB OUTPUT SOCKET
Connect the USB external appliance to the USB port and
switch it on.
The USB output on this power inverter provides a supply
of 5V DC power for external USB external appliances
(e.g. Lights, fans, radios).
The USB output it permanently on when the power
inverter is connected to a 12V input voltage.
Warning
The USB output on the power inverter is not designed for transferring data.
Do not connect memory sticks, MP3 player or similar data storage external appliances.
Do not connect any data transfer cables to the USB port!
5. CONNECTION OF EQUIPMENT
Most electrical tools, appliances and audio/video equipment have a label indicating power
consumption in amps (A) or watts (W). Total power connected equipment should be less than
within inverter’s rated power. If the power consumption is rated in amps, multiply them by the
AC voltage (110/220V) to determinate the wattage. For example, a television rated at 1 amp
with 220V voltage will use 220watts.
Resistive loads, such as incandescent lights, are the easiest for the inverter but the larger
resistive loads such as electric stoves or heaters might require more power. Inductive loads,
such as TV’s and audio players (any device with a transformer in it) require more current to
operate than a resistive load of the same power rating. Induction motors as well as some
televisions may require 2 or 6 times of their power rating to start up. Such devices may require
repeated switching of the inverter power ON/OFF in order to get them started. The most
demanding are those devices that start under load, i.e. compressors and pumps. Since the
electrical characteristics of the connected equipment vary widely you might have to try to find
out if it can be started at all and how long it can run.

Connecting the inverter directly to the battery
Figure 1 - Loosen the caps on the terminals and
slide the lugs between the cap and the
base. Then tighten firmly.
Figure 2 - Open the alligator clips and attach then
to the appropriate battery terminals.
Connect the red alligator clip to the (+)
positive battery terminal and the black
alligator clip to the (-) negative battery
terminal.
