not exceed the inverter's capacity. In this case, use a more powerful
inverter.
Lots of devices need a larger amount of power during the start-up period
(switch-on power). This power can be several times more important than
the operating power. You will usually find this phenomenon with devices of
the "inductive" type, like motored devices. A 600 W electric drill can easily
need 1800 W of switch-on power.
With some devices the power will be much higher than the mentioned
power. Take a microwave oven as an example. The operating power is in
fact the power needed to cook. The actual operating power is several times
higher. The needed power for an electric drill depends on the load onto the
drill (drilling through wood will require less power than drilling through
concrete).
Choose your inverter considering these specifications since the inverter has
to be able to deliver this kind of power. Apply the following principle when
choosing an inverter:
Multiply the device's operating power by 3. This value has to be
inferior to the continuous (maximum) power of the inverter:
operating power of the device x 3 < inverter's capacity

7. Connection
Follow these guidelines in order to avoid damaging the inverter and the
connected device.
Refer to the illustrations on page 2 of this manual.
1. Install the inverter in a well-ventilated place.
Make sure to leave sufficient space between the device's back panel (fan
output) and the next object.
2. Connect the included cables to the battery.
Connect the black wire to the black connection on the back of the inverter
(DC input, see fig.) and to the negative battery terminal (–). Connect the
red wire to the red connection at the back of the inverter and to the positive
battery terminal (+).
An incorrect connection can damage the inverter and will void the warranty.
Do not extend the included cable as this can lead to a high voltage
loss or cable overheating.
3. Connect the device.
You can extend the connection cable to the device without problems.
4. Switch on the inverter.
The green LED lights up. The inverter delivers an output power of 230 Vac.
5. Switch on the connected device.
Respect the order of the aforementioned steps. To switch off the system,
proceed in reverse order.
