INSTRUCTIONS FOR USE
Position of the Power Inverter
•
No liquid may be allowed to enter the unit.
•
The ambient temperature should be between -10 degrees and
+40 degrees C. Do not place on or directly adjacent to a heat source.
•
Do not expose to direct sunlight.
•
Leave a space of 2-4cm to allow adequate air circulation.
•
Do not place any objects on top of the power inverter.
•
Do not use close to flammable materials or in places where flammable
vapours or smoke is present.
Power Supply
The power source needs to be a minimum of 11 volts to a maximum of
15 volts DC and have enough permanent output to operate the unit. To
establish the estimated necessary power supply (in amps), divide the
respective output (in watts) of the attached appliance by the incoming
voltage being 12 volts in the case of a car battery.
Unpack the power inverter and ensure that the switch is in the OFF position.
Connection via the Vehicle’s Battery
•
It is recommended running the vehicle’s motor for approx. 15 minutes
every hour to avoid the battery from going flat.
•
Connect the power inverter to the battery, using the battery clamps included. Pay attention to polarity when
attaching the clamps to the battery. Red terminal is positive (+) and black terminal is negative (-). See Fig. 1
•
The power inverter can be operated when the motor is running or when the motor is at a standstill.
•
It is possible that the power inverter may not work due to the voltage drop during the starting process.
•
If not in use, disconnect the power inverter from the battery.
Alarm in case of Battery Voltage Drop
The power inverter switches off automatically when the voltage drops below 10 volts. A high pitched alarm will sound
and a red light will appear. Refer page 6 under control functions, 3. Overload fault indicator.
Protective Features
•
Low-voltage of the battery
- may damage the battery but not the power inverter as it switches off. Once the normal
operating status is reinstated, the unit can be operated again.
•
Overload protection
- If the incoming voltage exceeds 15 volts DC, or if the permanent output is exceeded, the unit
switches off automatically.
•
Short-Circuit
- If the wires are crossed or the attached appliance has short-circuited, the power inverter 35 amp
fuses will blow to prevent damage to the power inverter. If the fuse blows, contact the After Sales Support helpline
for replacement of defective fuses.
