USER GUIDE
WARNINGS AND SAFETY
For safe operation and ideal performance, the iTechworld inverter must
be correctly installed and operated correctly. Please carefully read,
understand and follow all instructions and guidelines in this User Guide.
iTechworld recommends that all wiring and installation be done by a
certified technician or licensed electrician to ensure all applicable
electrical wiring regulations and installation codes are met. Failure to
follow these instructions may result in damage to the unit and could
also result in may result in death or serious injury.
Disclaimer:
While iTechworld has taken every precaution to ensure the accuracy of
the contents of this user guide, iTechworld assumes no responsibility for
any errors or omissions.
Furthermore, all specifications and functionality may change at any time
without notice.
Important:
Please read and understand the entirety of this user guide before using
your iTechworld inverter. Any misuse may result in damage to the unit
and/or cause harm or serious injury to the user.
!!FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN
DEATH OR SERIOUS INJURY!!
1. DANGER ELECTRICAL SHOCK HAZARD: Do not disassemble the
inverter. The inverter contains hazardous voltages inside.
Attempting to service any internal components will void
warranty and may result in death or serious injury.
2. DANGER ELECTRICAL SHOCK HAZARD: Do not expose the
inverter to bilge water, rain, snow, spray or dust. The inverter is
only intended for indoor use only.
3. DANGER ELECTRICAL SHOCK HAZARD: Operating the inverter
without proper grounding may result in death or serious injury.
Please ensure that proper ground connections are made during
installation. Please consult a licensed electrician if you are
unsure.
4. DANGER ELECTRICAL SHOCK HAZARD: Before attempting to
clean the inverter disconnect DC power and any circuits
connected to the inverter.
5. DANGER ELECTRICAL SHOCK HAZARD Keep away from children:
The inverter produces 240VAC, treat the AC output receptacles
the same as regular wall AC sockets at home.
6. DANGER: Do not under any circumstances connect the output
terminals of the inverter to an incoming AC source, this will
result in permanent damage to the inverter and void all
warranties.
7. DANGER EXPLOSION HAZARD: Do not use the inverter in an
environment where flammable fumes or gases are present
(such as gas bottles, petrol engines or lead acid battery
compartments)
8. Warning: Do not use substandard or damaged wiring with this
inverter, it may cause fire or a shock hazard.
9. Warning: When connecting the DC input, pay close attention to
the polarity of the input. As a reverse polarity connection will
cause permanent damage to the inverter and void all warranty.
10. Warning: When using inductive loads, please note that they can
draw up to 10 times its rated power draw. Furthermore, when
running appliances with a locked rotor current such as pumps,
or compressors, please turn of other non-essential appliances
that are connected to the inverter.
11. Warning: Please ensure all ventilation vents and fan vents are
not obstructed in any way. Please keep a minimum of 60mm
distance around the sides of the inverter to ensure adequate
ventilation. Failure to do so may result in fire or failure of the
inverter.
12. Warning: Avoid dropping any metal tools or objects on the
battery. Doing so could create a large spark or short circuit
which may cause an explosion.
13. Warning: Batteries can supply very large currents in the event
of a short circuit. A fuse must be installed on the positive supply
cable as close as practical to the battery. Failure to do so
provides inadequate protection in the event of a short circuit
and may result in a fire hazard.
14. LIMITATIONS OF USE:
Do not use in connection with life support systems or other
medical equipment or devices.
USER GUIDE
Introduction:
Thank you for purchasing the iTechworld pure sine wave inverter. These
inverters produce a pure sine wave output, matching the output of your
home 240V AC power point, allowing you to power sensitive electronic
appliances, such as laptops and many AC powered devices anywhere.
The iTechworld pure sine wave inverter also provides 5V USB power,
allowing you to power or charge many devices that require 5V USB
power.
Key Features:
- Remote operation available (Optional Accessory)
- 1 x USB port: 5V 2.1A
- Temperature and load controlled cooling fans for quiet and
optimal performance
- Pure sine wave output
- LED status indicators with audible alarm
- Australian standard 240V receptacle with hard wire terminal
connections (only on 3000W model, requires licensed electrician
for installation)
- Heavy duty aluminium case for durability and cooling.

B. Main Switch
The main switch is used for turning ON or OFF the output of the
inverter.
With the switch in the ON position, the Power indicator LED(C) will
glow green, and a single beep will be emitted to indicate 240VAC is
being produced.
C. Power LED indicator
Illuminates green to show that the inverter is outputting 240VAC
power.
D. Fault LED indicator
Will illuminate/flash red when a fault is detected, the 240VAC output
will be turned off. Please refer to the troubleshooting section.
E. 5V USB Socket
USB socket is for charging/powering 5V USB devices, such as mobile
phones. When the inverter is connected to a battery, the 5V USB port
will continuously output power, regardless of whether the Main
Switch(A) is in the ON or OFF position.

G. Chassis Ground Terminal
A proper ground connection must be made before using the inverter.
The inverter is grounded through the grounding terminal located on
the front panel near the 240V outputs.
The chassis ground terminal must be connected to the negative
terminal of the DC input. Please use minimum 1.5mm² cable. Please
consult with a Licensed Electrician to ensure your application meets
current Australian/New Zealand standards.
