2-4-3 Before proceeding further, carefully check that cable you have just connected
negative terminal of inverter to the negative output power source.
2-4-4 Connect the cable from the positive terminal of the inverter to the positive
terminal of the power source. Make a secure connection.
2-4-5 Set the power switch to the ON position; you will hear the "bi-bi-bi" sound. At the
same time, the display is showed the word "ASIAN" for two times. After that,
you will hear the continuous sound from internal alarm. Then, the AC voltage
shows on the display. It means the device has done the operation.
2-4-6 Set the power switch to the OFF position; the device shut down completely.
2-4-7 Please use a power meter accurately measure the true output R.M.S. voltage of
inverter. We use a power meter such as IDRC CP-350 or ABM 2019 to measure
our product.

2-5 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 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 of ground bus).
WARNING!
Make sure all the DC connections are tight (torque to 9-10 ft-lbs,
11.7-13Nm). Loose connections will overheat and could result in
a potential hazard.
CAUTION!
Reverse polarity connection will blow a fuse in inverter and may
permanently damage the inverter.
Damage caused by reversing polarity connection is not covered by
our warranty.
WARNING!
You may observe a spark when you make this connection since
current may flow to charge capacitors in the power inverter.
Do not make this connection in the presence of flammable fumes.
Explosion or fire may result.
