SECTION 1 | Introduction & General Safety
Introduction
Thank you for choosing to purchase a Samlex inverter. Our power inverters are designed
to be your best companion at home, in the ofce and when travelling.
The inverter can be used to operate lap tops, portable electronics, most small TVs, VCRs,
sound systems, small handy tools and other portable sensitive electronic products. This
power inverter has a rated output of 120 Watts.
General Safety
Read these General Safety, Installation, and Operation Guidelines carefully before using
your inverter.
- Keep away from children.
- Never attempt to operate the inverter from any power source other than a 12 VDC
power source.
- Make sure the power consumption of the appliance or equipment you wish to
operate does not exceed 120W.
- When operating the inverter with a car or marine battery, start the engine every 30 to
60 minutes and let it run for approximately 10 minutes to recharge the battery.
- Do not use the inverter near any ammable gases or liquid.
- Do not expose the inverter to moisture.
- Avoid placing inverter near sources of heat or under direct sunlight.
- Make sure inverter is well ventilated during use. Keep a clear space of 10 cm around
the inverter (Fig. 4).
- The inverter has no ON/OFF switch. It will switch on automatically after plugging
into a 12V battery through the 12V plug adaptor. Unplug the inverter from the 12V
power source when not in use, as it will drain 0.5A from the battery even if no load
is connected.

SECTION 3 | Operation Guidelines
Operation
- A detachable 2' DC input power cord (7, Fig. 2B) 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. 2B).
- Connect the detachable DC input power cord (7, Fig. 2B) by sliding the mating Power-
pole connector (10, Fig. 2B) into the DC inlet Powerpole connector (6, Fig. 2A).
- Plug in the 12V plug adaptor (8, Fig. 2B) of the DC input cord into the 12V outlet of the
battery supply.
- When the LED Status Indicator (2, Fig. 1) is GREEN, the inverter's AC Outlet (3, Fig.1) and USB
port (1, Fig.1) will have voltage outputs.
- Insert plug of your electrical appliance into the AC Outlet (3, Fig. 1) of the inverter.
- Remove the inverter from the 12V outlet when not in use. This will prevent unnecessary drain
from the battery.
The inverter is protected against the following abnormal conditions:
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.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 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. 1) will turn ORANGE.
- The unit will reset automatically on cooling.
Low DC Input Voltage
- The unit will shut down if DC input voltage is < 10 VDC.
- The LED Status Indicator (2, Fig. 1) will turn ORANGE.
- The unit will reset automatically when the voltage rises to 11.5 VDC.

LED STATUS INDICATOR INVERTER & USB STATUS
LED is OFF AC output is available: No USB power
No AC output: 15A input side fuse is blown
GREEN USB normal
ORANGE Inverter shut down
due to:
- Over temperature
- Low DC input voltage
- High DC input voltage
USB normal
RED No USB power
SECTION 3 | Operation Guidelines
High DC Input Voltage
- The unit will shut down if DC input voltage > 16.5 VDC.
- The LED Status Indicator (2, Fig. 1) turns ORANGE.
- The unit will reset automatically when voltage is < 16.5 VDC.
Over Voltage On USB Port
- USB output is shut down if USB output > 6.2 VDC.
- The LED Status Indicator (2, Fig. 1) will be OFF or RED.
Operational conditions indicated by the LED Status Indicator (2, Fig. 1) are given in the
following table:
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.
The fan may not be running all the time.
- Place the unit in a cool, well ventilated space that has adequate cool replacement
air (Fig. 4).
