WARNING!
Shock Hazard. Before proceeding further, carefully check the inverter is NOT connected to any batteries, and that all wiring is disconnected from any electrical sources. Do not connect the output terminals of the inverter to an incoming AC source.
2-3 Installation:
Where to install:
The power inverter should be installed in a location that meets the following
requirements.
2-3-1 Dry – Do not allow water to drip or splash on the inverter.
2-3-2 Cool – Ambient air temperature should be between -20°C and 50°C, the
cooler the better.
2-3-3 Safe – Do not install in a battery compartment or other areas where
flammable fumes may exist, such as fuel storage areas or engine compartments.
2-3-4 Ventilated – Allow at least three inch of clearance around the inverter
for airflow. Ensure the ventilation openings on the rear and bottom of the
unit are not obstructed.
2-3-5 Dust-free – Do not install the inverter in a dusty environment where are
dust, wood particles or other filings/shavings.
These dusts can be pulled into the unit when the cooling fan is operating.
2-3-6 Close to 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 2-5).
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 that will damage the
inverter.
2-4 Quick Hook – Up and Testing:
2-4-1 Unpack and inspect the power inverter, check to see that the power switch is in the OFF position.
2-4-2 Connecting with input source:
For 200W inverter:
Plug the inverter’s DC lighter into the vehicle cigarette lighter socket, then
follow point 2-4-5.
For 350W inverter:
Connect the cables to the power input terminals on the rear panel of power
inverter.
The red terminal is positive (+) and black terminal is negative (-).
Insert the cables into the terminals and tighten relative nut to clamp the
wires securely. Follow point 2-4-3.
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 of
fire may result.
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.
2-4-3 Before proceeding further, carefully check that cable you have just connected negative terminal of inverter to the negative output power source.
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.
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.
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.
2-4-5 Set the power switch to the ON position; you will hear the “bi-bi-bi”
sound, then the inverter comes into standby state.
2-4-6 Set the power switch to the OFF position; the device shut down
completely.
2-4-7 Please use a power meter to accurately measure the true output R.M.S.
voltage of inverter.
Our company uses a power meter such as IDRC CP-350 or ABM 2019 to measure our
product.
2-5 Making DC Wiring Connections:
Follow this procedure to connect the battery cables to the DC 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 warnings are due to DC voltage drop across the cables
from the inverter to the batteries.
The longer and narrower these cables, the greater the voltage drop.
WARNING!
The installation of a fuse must be on positive cable. Failure to place a fuse on “+ “cables running between the inverter and battery may cause damage to the inverter and will void warranty.
Increasing your DC cable size will help improve the situation.
Our company recommends the following cables for optimum inverter performance
(apply both 120V and 230V versions)
200W
350W
Also, use only high quality copper wiring and keep cable length short from 3-6 feet.
200W & 350W
2-6 Inverter 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.
2-6-1 Controls and indicators:
The ON / OFF switch turns the control circuit in the power inverter on and
off.
The inverter operates from an input voltage range:
10.0 to 16.0 VDC for 12V models
20.0 to 32.0 VDC for 24V models
42.0 to 62.0 VDC for 48V models
The inverter will indicate high and low DC voltage conditions as follows:
2-6-2 Over Voltage Protection indicator: (OVP)
The over voltage indicator indicates that the power inverter has shut itself
down because its input voltage exceeded 12V/24V/48VDC (Ref. point 2-7-1).
2-6-3 Under Voltage Protection indicator: (UVP)
The under voltage indicator indicates that the power inverter has shut itself
down because its input voltage fell below 12V/24V/48VDC (Ref. point 2-7-1).
2-6-4 Over Temp Protection indicator: (OTP)
The over temp indicator indicates that the power inverter has shut itself down
because its temperature 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 automatically back up, once it has cooled
off.
2-6-5 Over Load Protection indicator: (OLP)
The overload indicator indicates that the power inverter has shut itself down.
When output voltage over its continuous voltage, then must return to operate
manually.
2-7 Cooling Fan Working Code:
Cooling fan of inverter start to work when turning on the inverter, in other
words, the cooling fan is always turned on.
If the ventilation opening is obstructed, the inverter will enter over
temperature protection mode (OTP) and inverter shut down. When the temperature
comes down to normal situation, the inverter will turn on automatically
Maintenance:
Very little maintenance is required to keep your inverter operating properly.
You should clean the exterior of the unit periodically with a dry cloth to
prevent accumulation of dust and dirt. At the same time, tighten the screws on
the DC input terminals.

Important Safety Instructions
WARNING!
Before you install and use your inverter, be to read and save these safety instructions.
6-1 General Safety Precautions
6-1-1 Do not expose the inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or obstruct the ventilation openings. Do not install the inverter in a zero-clearance compartment. Overheating may result.
6-1-2 To avoid a risk of fire and electronic shock. Make sure that existing wiring is in good electrical condition; and that wire size is not undersized. Do not operate the inverter with damaged or substandard wiring.
6-2 Precautions When Working with Batteries
6-2-1 If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters eye, immediately flood eye with running cold water
for at lease 20 minutes and get medical attention immediately.
6-2-2 Never smoke or allow a spark or flame in vicinity of battery or engine.
6-2-3 Do not drop a metal tool on the battery. The resulting spark or short-
circuit on the battery or other electrical part may cause an explosion.
6-2-4 Remove personal metal items such as rings, bracelets, necklaces, and
watches when working with a lead-acid battery.
A lead-acid battery produces a short-circuit current high enough to weld a
ring or the like to metal, causing a severe burn.
