CAUTION:

Each model is design to work up to its maximum rated power load.
Please check carefully to ensure applications used are within the rated power range.
Any attempt of misuse to overload will trigger the overload protection and may cause
damage to both unit and application used. Mercury will not be responsible for any
damaged caused by misusage of the product

WARNING

Contain high voltage and high current! Do not open or

attempt to repair yourself!

INTRODUTION:

Thank you for choosing this Modified Sine Wave Inverter. This inverter is capable of converting DC power
input to AC power output that has similar output signal wave as normal domestic mains. Unlike pure sine
wave inverters, modified sine wave inverter is not recommended for powering voltage sensitive or
inductive equipment. For inductive load such as fluorescent light, acoustic equipment and equipment
contain motor such as fan and compressor, we recommend to use our pure sine wave inverter instead.
Below shows the differences in output voltage waveform between pure and modified output:

User Manual

FRONT PANEL:

- ON/OFF SWITCH – rocker switch to switch unit on and off

- POWER INDICATOR – solid green LED indicates unit has been switched on

- FAULT INDICATOR – solid on or flashing red LED indicates fault has occurred,
refer to fault code for interpretation

- USB POWER SOCKET – 5V 1.0A USB power supply socket for charging smart phone camera etc

- UK AC MAINS SOCKET – output UK mains socket provide 230Vac 50Hz mains power

- GROUND CONNECTION – star washer and nut for ground connection to the outer case (normally
connected to the vehicle chassis)

BACK PANEL:

- INPUT BATTERY NEGATIVE CONNECTION – battery input connection to connect negative output
of the DC power source

- INPUT BATTERY POSITIVE CONNECTION – battery input connection to connect positive output of
the DC power source

- FUSES – location of the fuses

- FAN DUCT –fan for cooling - do not obstruct

Temperature and load controlled multi-speed cooling fan:

The cooling fan is designed to run at a speed in proportion to the load, this minimises the running noise
and extend fan life.

- At load lower than 40% or inner temperature less than 30°C the fan will not operate

- At load between 40% - 60% the fan will operate at 40% of its maximum speed

- At load between 60% - 80% the fan will operate at 60% of its maximum speed

- At load between 80% - 100% the fan will operate at 80% of its maximum speed

- At 100% load or inner temperature exceeds 45°C the fan will operate at 100% of its maximum
speed

INSTALLATION:

Location – it is important to for the location of the inverter to meet below requirements:

- Dry environment where there should be no risk of the inverter coming into contact with water

- A cool shaded environment where temperature should be 0°C – 40°C,
not to be placed near any heat source and avoid direct sunlight

- A well-ventilated area, minimum clearance of two inches should be allowed in front of the
ventilation duct and fan. Please ensure free flow of air around the unit, if the unit is used to its full
load, an external fan may be used to aid the cooling of the unit

- Not to be place in the same compartment as the battery or together with flammable substances

- Avoid dusty environments, dust can cause blockage of airflow within the inverter
and cause the unit to overheat

- Avoid using long input cable run as input voltage can be affected by cable resistance and heat

User Manual

Mounting – The unit should be mounted horizontally, we do not recommend mounting the unit vertically.

Connection:

- Please ensure the ON/OFF switch on the inverter is in the OFF position and the voltage of power
source matches the required inverter input voltage, if the power source is from a DC power supply
please ensure it is switched off also

- Connect the invert to battery / DC power source. Using provided black cable; connect the
black negative terminal to the negative output of the power source. Using provided red
cable; connect the red positive terminal to the positive output of the power source.

- Before connect the inverter to appliances please ensure the appliance power rating is within the
inverter’s continuous output power. After connected, double check all connections are correct
before switch on the inverter and appliance. If more than one appliance is being used on the
same inverter, please ensure appliances are switched on one after the other, after the inverter has
been switched on. This is to avoid the inverter undergoing any surge current from individual load
all at once.

Please beware, any use of cables and accessories other than the ones provided may cause damage,
Mercury will not take any responsible for damage caused by use of third party accessories. For cable
cross-section requirement for different models, please refer to accessory appendix at the back of this
manual. Some models with higher power may have 2 pairs of terminals that require 2 pairs of cable to
help with the high input current. ALWAYS ensure the correct polarity is connected before start, DO NOT
reverse input polarity as it will blow up the fuse and may cause permanent damage to the inverter.

Input power specification:

For an inverter running from a battery, the duration of the appliance is determined by these 3 factors:

- Voltage of input power

- Power of the appliance

- Capacity of the battery

For example an appliance of 100W running on a 12V input power inverter will require:

100/12 = 8.33 Amp/hour

A typical 12V car battery has capacity of around 80Ah; to run the above example on this battery we can
estimate it will be capable of duration of:

80/8.33 = 9.6 hours

In reality, this number will be lower due to the power lost from the efficiency in power conversion (in this
case over 80% of DC power will be used to convert to AC power) power lost from the input/output cable,
depreciation of battery capacity on older batteries, and temperature (a cold battery holds less capacity).
