Fuse Replacement; Technical Data; Troubleshooting - VOLTCRAFT WR 300-12 Bedienungsanleitung

4. Insert the cigarette lighter plug into the car cigarette lighter.
You can operate the car plug with the engine running or switched off. However, do not
start the engine while the car plug is in operation, as the power supply to the cigarette
lighter outlet will be interrupted during ignition. When operating the car plug at a high load
for a long time, it is advisable to start the engine in order to recharge the vehicle battery.
Operate the load
1. Connect the load to the isolated ground socket / USB socket.
The total consumption of the USB device connected to the inverter must not be higher
than 1.5 A.
The three output can be operated at the same time.
2. Switch the ON / OFF switch to the ON position.
3. If the inverter is operating correctly, the connected loads will operate. The LED next to the
USB socket should light up in green. If the LED does not light up or it lights up in red,
immediately switch the inverter off, unplug the load and check the troubleshooting section.
4. If a resistive load of 200 W or above is connected to the inverter, the power output will be cut
immediately and the LED will turn from green to red. In this case, restart the inverter.
If the input voltage drops below 10.5 V/DC, an audible alert will be heard. If the input
voltage continues to drop below 10 V/DC, the power output of the isolated ground socket
will be cut, but the USB power output will still function.

FUSE REPLAcEmENT

There are two fuses in this device. There is a 15 A safety fuse built into the cigarette lighter plug.
There is also a 40 A flat car fuse built into the back of the inverter.
Fuses are replacement parts that are not covered by the warranty!
To replace the fuse of the cigarette lighter
1. Unplug the cigarette lighter plug from the socket.
2. Turn the plastic knurled nut at the tip of the inverter carefully counterclockwise to open the
fuse compartment.
3. Replace the broken fuse with a new one of the same type (refer to TECHNICAL DATA).
4. Close the fuse compartment.
To replace the fuse of the inverter
1. Unplug the inverter from the power source.
2. The fuse is located at the back, above the red and black terminals.
3. Flip from the left to open the fuse cover. Do not intend to detach the whole fuse cover, it is
designed to connect with the inverter body on the right side.
4. Pull the car fuse out and replace the broken fuse with a new one of the same type (Refer to

TECHNICAL DATA).

5. Close the fuse compartment.
cLEANING
Unplug the inverter from the power source. Wipe the housing of the inverter with a slightly
damp cloth. Only use water to moisten the cloth. Do not use chemicals or cleaning agents
when cleaning.

TROUBLEShOOTING

Symptoms Possible cause and solutions
The LED does not light up. The fuse may be broken. Check the inverter fuse. If
you are using the cigarette lighter plug, check also the
fuse of it. Replace the fuse if necessary. (Refer to FUSE
REPLACEMENT)
The LED lights up in red. •

•
Low battery - Check if the power source is having a
low voltage.
Overload - Check if the output loading is too high.
Over heat -Check if the output loading is too high or if
the ventilation of the inverter is poor.
Short circuit - Check if the output or the load is short-
circuited.
Restart the product to resume the product operation
when the problem is solved.
Consult an expert if necessary.
