IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important Safety and Operating Instructions. Please read before

using this unit .

The following safety symbols will be used in this manual to highlight safety

and information:

WARNING!

Indicates possibility of physical harm to the user in case of non-compliance.

!CAUTION!

Indicates possibility of damage to the equipment in case of non-compliance.

Please read these instructions before installing or operating the unit to prevent personal

injury or damage to the unit.

WARNINGS!

1. DO NOT OPEN TO REDUCE RISK OF FIRE OR ELECTRIC SHOCK. THERE ARE NO USER

SERVICEABLE PARTS INSIDE—REFER TO QUALIFIED SERVICE PERSONNEL.

2. It is recommended that you return your inverter to a qualied dealer for any service

or repair. Incorrect assembly may result in electric shock or re.

3. To reduce the risk of electric shock, unplug the DC input from the battery before

attempting any maintenance or cleaning.

4. To reduce risk of damage to electric plug and cord, pull by plug rather than cord when

disconnecting the unit.

5. An extension cord should not be used unless absolutely necessary. If an extension cord

is used, make sure that it has 2-prong, male plug (NEMA1-15P) and 2-prong, female

receptacle (NEMA1-15R). The size of the current carrying conductors should be such

that they are able to carry at least 2.5A for the length of the extension.

6. Place the unit in an area that will allow air to ow freely around the unit. DO NOT

block or obstruct vent openings or install the unit in an enclosed compartment.

7. Keep the unit away from moisture and water.

8. NEVER OPERATE TWO OR MORE UNITS IN PARALLEL.

9. Precautions when working with batteries.

- Batteries contain very corrosive diluted Sulphuric Acid as electrolyte.

Precautions should be taken to prevent contact with skin, eyes or clothing.

- Batteries generate Hydrogen and Oxygen during charging resulting in

evolution of explosive gas mixture. Care should be taken to ventilate the

battery area and follow the battery manufacturer’s recommendations.

- NEVER smoke or allow a spark or ame near the batteries.

- Use caution to reduce the risk of dropping a metal tool on the battery. It

could spark or short circuit the battery or other electrical parts and could

cause an explosion.

- Remove metal items like rings, bracelets and watches when working with bat-

teries. The batteries can produce a short circuit current high enough to weld a

ring or the like to metal and thus cause a severe burn.

- If you need to remove a battery, always remove the Negative Ground Terminal

from the battery rst. Make sure that all the accessories are OFF so that you do

not cause a spark.

!CAUTIONS!

1. Please refer to 12V Plug Adapter (8) at Fig 2.3. Please ensure that the battery is

connected with correct polarity - Positive of the battery to the tip of the Adapter (8)

and the Negative of the battery to the spring contacts of the Adapter (8). Reversal of

polarity will blow 15A fuse (5). Reversal of polarity may result in permanent damage

to the unit and to the load. DAMAGE DUE TO REVERSE POLARITY IS NOT COVERED

UNDER WARRANTY.

2. The inverter has no ON/OFF switch. It will switch ON automatically after plugging

into 12V battery through the 12V Plug Adapter. Unplug the inverter from the battery

when not in use, as it will drain 0.5A from the battery even if no load is connected.

3. Ensure that the unit is connected to 12V battery and the battery charger voltage is

≤ 16.5V. Higher DC input voltage will damage the unit.

SECTION 3 | Installation & Operation

INSTALLATION & OPERATION

- Ensure installation clearances are as shown in Fig. 3.1 above for proper cooling.

- A detachable 2' DC input power cord (7, Fig. 2.3) has been provided.

- This unit does not have a power ON/OFF switch. The unit will switch ON automatically as soon

as 12 VDC power is fed from the battery through the 12V plug adaptor (8, Fig. 2.3).

- Connect the detachable DC input power cord (7, Fig. 2.3) by sliding the mating

Battery Modular connector (10, Fig. 2.3) into the DC input connector (6, Fig. 2.2).

- Plug in the 12V Plug Adaptor (8, Fig. 2.3) of the DC input cord into the 12V outlet of the

battery supply.

- When the LED Status Indicator (2, Fig. 2.1) is GREEN, the inverter's AC Outlet (3, Fig. 2.1) and

USB port (1, Fig. 2.1) will have voltage outputs.

- Insert plug of your electrical appliance into the AC Outlet (3, Fig. 2.1) of the inverter.

- Remove the inverter from the 12V outlet when not in use. This will prevent unnecessary drain

from the battery.

SECTION 3 | Installation & Operation

PROTECTIONS

Overload and short circuit on the AC output side

- If the load exceeds 120W, the output voltage will start dropping, but the unit will

NOT shut down.

- The LED Status Indicator (2, Fig. 2.1) will remain GREEN.

-The output voltage waveform will be distorted and will not have pure sine waveform,

but will be clipped at top and bottom and will look like a square waveform.

- There will be excessive RF noise.

- The until will reset automatically once the overload/short circuit is removed.

Over temperature due to fan failure or due to lack of cool replacement air

- The unit will shut down if temperature of hot spot inside the unit > 105°C. The LED

Status Indicator (2, Fig. 2.1) will turn ORANGE.

- The unit will reset automatically on cooling.

Low DC Input Voltage

- The LED Status Indicator (2, Fig. 2.1) will turn ORANGE.

- The unit will reset automatically when the voltage rises to 11.5 VDC.

High DC Input Voltage

- The unit will shut down if DC input voltage > 16.5 VDC.

- The LED Status Indicator (2, Fig. 2.1) turns ORANGE.

Over Voltage On USB Port

- USB output is shut down if USB output ≥ 6.2 VDC.

- The LED Status Indicator (2, Fig. 2.1) will be OFF or RED.

Operational conditions indicated by the LED Status Indicator (2, Fig. 2.1) are given in

the following table:

SECTION 3 | Installation & Operation

Cooling

- The inverter has a temperature controlled fan for cooling.

- The fan will start once the temperature of the hot spot inside the unit exceeds

70°C / 158°F. Note: In cooler ambient temperature and/or at no/low loads, the hot spot

may not reach 70°C / 158°F and hence, the fan will be OFF.

- If the fan fails, or if adequate cool air change is not available, temperature of hot spot

will continue to rise and at ≥ 105°C / 221°F, AC output will be shut down. AC output

will be restored when the unit cools down sufciently.

- Place the unit in a cool, well ventilated space that has adequate cool replacement

air (Fig. 3.1).
