General Information – Modified or Pure Sine Wave with USB-Port
The inverter supplies, depending on the series a pure sine or a modified sine voltage (see
illustration below), which can be used to operate common electrical devices whose power
requirements match the maximum output of the inverter.
Electrical devices with a sensible electronic system (electrical measuring devices, coffee
pad machines, electronically controlled charging stations etc.) cannot be operated with a modified sine voltage as this does not provide a voltage
sufficiently constant for such devices. When connecting a modified sine inverted to a device the first time, close attention should be paid to how the
temperature of the device develops and any unusual noises. Various devices cannot process such a voltage. In some cases it can lead to a
humming noise and/or high temperature or a device malfunction and failure. Such devices can suffer permanent damage. These are not compatible
with the inverter and should not be used together.
When connecting the modified inverter to a highly valuable or sensible device, manufacturer's advice should be considered.
In case of pure sine inverters, no such limitations exist currently.
To ascertain if your inverter supplies a pure sine or modified voltage, please refer to the series label (on the underside of the inverter).
The power output of a modified sine inverter can not be properly measured with a conventional multimeter. The displayed voltage will be a highly
distorted value. The power output can only be measured properly through a RMS-suitable volt or multimeter.
Inverters with a USB slot can be used to operate/charge small devices such as mobile phones, laptop lamps or ventilators. The USB port supplies a
maximum of 5 volts and 500mA and is not a data port.

Important Safety Instructions

Before the first use, please read the following instructions carefully and pay close attention to all warnings, even if you are familiar with the
•
application of electronic devices.
Carefully store this manual for future reference. If you sell or pass on the inverter, be sure to pass along this manual as well.
•
In case of situations such as a storm/thunderstorm with a risk of lightning, please disconnect the inverter from the voltage source or from the
•
electrical system of your vehicle completely.
Position the inverter so that unobstructed access to the power socket or to the cable connections is guaranteed, so that if need be instant and
•
secure disconnection from the power source is possible.
An electrical consumer should always be disconnected from the inverter if not in use for a prolonged period.
•
The inverter must not be used for feeding into the current network of domestic installations.
•
Never leave the appliance unattended during operation.
•
The inverter may only be opened by a qualified electrician. Before opening the inverter must be disconnected from the power source.
•
The requirements of DIN VDE 0100 Part 717 should be complied with.
•
The inverter must not be connected to positively earthed electrical systems. In case of application with an automobile, ensure that the positive
•
terminal of the battery is not connected to the chassis of the vehicle.
Do not insert objects through the ventilation slots of the device.
•
If you notice any smoke, unusual noises or odors, switch off the inverter immediately and disconnect it completely from the power source. In
•
these cases, the inverter should not be used further.
Depending on the application situation and the electrical consumer from protection class I (with earth wire), always take appropriate measures
•
to protect against electrical shock (potential equalization, earthing, earth leakage circuit breaker etc.). If the inverter has a separate earth
connection, this can be used for such activities. In such cases, always contact a qualified electrician. For electrical consumers with protection
class II, these measures are not necessary.
