5 Intended use
The device is intended to supply 230 V to connected appliances generated from 12 V or 24 V input voltage. The de-
vice is designed to be used in motorhomes, campervans and coaches.
The model line includes two types of devices:
• The SM400-12, SM600-12, SM600-24, SM1000-12 and SM1500-12 models are inverters with modified sinu-
soidal wave output.
• The SP400-12 , SP600-12, SP600-24, SP1000-12, SP1500-12, SP1500-24, SP3000-12 and SP3000-24 models
are inverters with pure sinusoidal wave output.
The SP1000I-12, SP1500I-12 and SP2000I-12 models are featuring an integrated priority function (IVT) and a fuse-pro-
tected input (IEC) socket for the external power supply connection.
This product is only suitable for the intended purpose and application in accordance with these instructions.

6 Target group
The electrical power supply must be connected by a qualified electrician who has demonstrated skill and
knowledge related to the construction and operation of electrical equipment and installations, and who
is familiar with the applicable regulations of the country in which the equipment is to be installed and/or
used, and has received safety training to identify and avoid the hazards involved.
7 Technical description
The device has two main circuit stages to convert the 12 V DC or 24 V DC input voltage to AC output voltage. The
first stage consists of an isolated high frequency DC/DC converter to convert the 12 V DC or 24 V DC input voltage
to an output voltage up to 400 V DC. The final stage consists of a H-bridge that converts the DC high voltage bus to
230 V AC voltage.
The device has the following main features:
• Low consumption.
• Galvanically isolated input and output for increased safety.
• Temperature-controlled fan speed for quiet operation.
• Integrated priority switch between external mains network and the battery.
• Ready for On/Off remote control.
11

EN 
• Low battery voltage alarm.
• Low and high battery voltage shutdown.
• Overload shutdown.
• Protection against short-circuit, overtemperature, overload, and reverse polarity.
• So start function.
8 Before installation
Battery requirements
Battery type and size can strongly affect the performance of inverters. Therefore, the type of loads the inverter will be
powering and the duration of use between recharging must be indentified. To determine the minimum battery re-
quirements for an application, do the following:
1. Determine the wattage from the labels of each appliance to be used simultaneously from the inverter. Usual-
ly, power consumptions shown in watts. If it is shown in amps, multiply by the value by 230 V to determine the
wattage.
2. Estimate the number of hours the equipment will be in use before recharging of the battery.
3. Calculate the total energy required in Wh (Watt hours) by multiplying the time determined above with the sum of
wattage. Divide the result by 10 if the inverter input is 12 V, or by 20 if it is 24 V. The resulting value in Ah repre-
sents the power requirement of the application.
Note When possible, recharge the battery when about 50 % discharged or earlier. This gives the battery
a much longer life cycle, opposed to only recharging it when it is deeply discharged.
Troubleshooting interference problems
Some inexpensive sound systems may emit a buzzing noise from the loudspeakers when operated from the invert-
er. This occurs because the power supply in the sound system does not adequately filter the modified sine wave pro-
duced by the inverter. The solution is to use a sound system that has a high quality power supply, or use a pure sine
wave inverter. When the inverter is operating, it can interfere with television reception on some channels. If interfer-
ence occurs, try the following:
1. Make sure that the chassis ground screw of the inverter is connected to the ground of the vehicle.
2. Make sure that the television antenna provides an adequate signal and the antenna cable is in good condition.
3. Keep the cables between the battery and the inverter as short as possible, and twist them together to reduce
the radiated emissions.
4. Move the television as far away from the inverter as possible.
5. Do not operate high power loads with the inverter when the television is on.
Ground leak protection (excluding the SP1000I-12, SP1500I-12 and SP2000I-12
models)
NOTICE! Damage hazard
For the safe operation of multiple appliances, it is essential that a circuit breaker (residual current circuit
breaker) is built into the socket distribution circuit.
12

EN
The ground socket is designed for a safety system such as the residual current circuit breaker (RCCB). Connect resid-
ual current circuit breaker according to the following diagram:
fig. on page1
1. Connect the phase (P1) and neutral (P2) output to the residual current circuit breaker input.
2. Connect the inverter ground to one of the two wires connected to the residual current circuit breaker input.
3. Connect the neutral and the phase output from the residual circuit breaker input to the appliances.
4. Connect the ground of the inverter to the ground of the appliances.
NOTICE! Damage hazard
The diagram above refers to the connection of the inverter output only. The IEC connector of the external
mains input must be connected to the circuit breaker output of the external mains power source.
Ground leak protection (SP1000I-12, SP1500I-12 and SP2000I-12 models)
The output socket of the SP1000I-12, SP1500I-12 and SP2000I-12 models is protected with a fuse.
fig. on page1
To establish a TN type grounding arrangement, make sure the fuse is inserted into the fuse holder .
To establish a TE type grounding arrangement, make sure the fuse is not inserted into the fuse holder .
9 Installation
CAUTION! Damage hazard
Do not install the device close to heat sources or in not adequately ventillated places.
Note The device can be mounted in any position. If installed on a vertical surface, it is recommended to
keep the long side parallel to the floor.
Note Install the device as close to the 12 V / 24 V power source as possible.
fig. on page2
1. Mount the device by the four mounting flanges using appropriate screws.
NOTICE! Damage hazard
Before connecting the device, make sure that the power switch is in off position.
Note Use the supplied wires to connect the battery to the device. If the distance between the battery and
the device exceeds 2 meters, increase the cross-section of the wire to reduce voltage drop and power
losses.
fig. on page3
2. Connect the negative terminal of the battery to the negative terminal of the inverter .
13

EN 
NOTICE! Damage hazard
To protect the connected devices, install an inline fuse on the positive battery cable.
3. Connect the positive terminal of the battery to the positive terminal of the inverter .
4. Install the fuse into the inline fuse holder.
NOTICE! Damage hazard
Before connecting an appliance to the inverter, make sure it is turned off.
5. Connect the 230 V appliance to an output socket .
6. Turn the inverter on with On/Off switch .
Note When the inverter is turned on, the red and the green LED both turns on for 3 to 5 seconds. After
a short time, the red LED turns off and the green remains on and the device emits an acoustic signal. The
green LED indicates that the inverter is functioning properly.
NOTICE! Damage hazard
• When you plan to operate more than one appliance, connect the one with the higher load require-
ment first.
• Make sure that the combined load requirement of your appliances does not exceed the output rat-
ing of the inverter.
• When using an extension cord from the inverter to an appliance, the extension cord should not be
longer than 1.5 m.
• Do not connect the inverter to any AC load circuit in which the neutral conductor is connected to
the ground.
7. Connect additional 230 V appliances and turn them on.
8. To charge a 5 V appliance, connect it to the USB port .
10 Connecting the external mains power supply (SP1000I-12,
SP1500I-12 and SP2000I-12 models)
It is possible to connect an IEC cable into the external mains socket to feed the connected appliances directly with
AC voltage from the public power network.
fig. on page4
Connect the cable to the socket .
11 Connecting the remote control
