3. INTRODU TION
Read this user manual completely before using the device. In the appendices you will find the
technical specifications of the pure sine wave power inverters.
This DC-AC inverter converts a 12 or a 24 Volts DC voltage into a AC voltage with a pure sine
wave (100-127V/220-240VAC). With this device it is possible, with use of the right battery, to
supply equipment that normally requires a mains supply.
Important
Always check the actual power rating of the equipment (power consumption). In addition, bear
in mind the surge powers. hese (start-up) peaks can be as much as 5-7 times the continuous
power consumption. Check whether these values are within the capacity limits of the inverter.
Equipment with high surge power are for example: air conditioning, vacuum cleaner, tools and
pumps. If you want to use multiple equipment at the same time, then add up the power
consumption.
4. INSTALLATION
4.1 Mounting
The inverter must be mounted in a space that complies with the following:
- Mount the inverter in a dry place where there is no chance of it being affected by moisture or
dirt. Also be aware of moisture or dirt that can be sucked in by the fan.
- Leave enough space on all sides of the inverter (min. 10cm) for air circulation. Make sure that
there are ventilation vents.
- The ambient temperature must be between 0ºC and 40ºC. Ideal is between 15ºC and 25ºC.
- Keep the inverter out of the reach of children.
-
A working inverter produces a dangerous voltage.
- Do not use the inverter in places where gases are released or flammable materials are stored.

8
E N
N L
- The distance between inverter and battery should be as short as possible, but place the inverter
in a separate room.
- Place the inverter on a stable underground and prevent (heavy) vibrations and shocks.
4.2 Connection with the attery
Important
- Before connecting to the battery, make sure that the inverter is turned off.
- When the battery is connected a spark may be generated due to the internal capacitor being
loaded.
Preferably use the supplied battery cable set. If you want this inverter to have a permanent
connection to the battery, we recommend replacing the clamps with terminal rings. For the other
models, the connections to the battery already consist of terminal rings. With the models
FS2500&NK2500 and FS3000&NK3000 two red and two black cables are included. In this case,
always connect both cables on the + and - side!
If you wish to use an own cable set, keep the cables as short as possible and ensure the connections
make good contact. Below formula indicates the required cable thickness
(Watt/voltage) x length in meters x 0,2 = cable in mmq
Example (1500W/12V) x 2 meters x 0,2 = 50mmq
Working method:
1. Connect the cables to the inverter first:
the red cable to the red + input connection. The black cable to the black – input connection.
Tighten the connections firmly.
2. Connect the other side of the cable to the battery:
The red cable to the + pole of the battery. The black cable to the – pole of the battery.
Important
Make sure that you connect the correct cable to the correct pole! he inverter can become
broken in this case. he repair costs are not covered by the guarantee.

E N
N L
Grounding
The AC output ground wire should be connected with the grounding point for the connected
equipment. Also wire the ‘ground’ connection on the inverter with the chassis of the vehicle or
the minus (6mmq wire).
4.3 Connection with the equipment
All inverters from the FS&NK series have a socket for the connection of the 110/230VAC
equipment. The models from 1500Watt have double sockets.
When connecting multiple users it is important that the total load (Watts) and surge powers fall
within the capacity specifications of the inverter.
Important
- If the surge power is exceeded, the inverter will become heavily damaged. Repair costs will
not be covered by warranty.
- Don’t mount the cables against the housing of the inverter.

10

4.4 The inverter in com ination with other AC power supplies
In many situations it is desirable that the equipment will work on the mains supply (or
generator) when this is available. The inverter and mains supply (or generator) then become one
circuit. Pay attention to the following:
Important
At the presence of a second power supply (mains, generator) this 110/230VAC will be parallel
on the output of the inverter. his will damage the inverter heavily!. he repair costs are not
covered by warranty. If you want the equipment to work on both an inverter and a second power
source, then mount the power transfer switch. Important feature is that this power transfer
switch is bipolar.
The power transfer box takes care of automatic switch between the two 110/230VAC circuits,
without any intervention for the connected equipment. A back-up system also can be created this
way.

4.5 Insulation monitoring
Is this inverter being mounted in a vehicle of any other mobile or movable unit? And is the
110/230VAC going to be used outside the vehicle/unit? Then please pay attention to the
following:
Important !
If this inverter is used in mobile unities, like mobile workplaces, fire trucks, workmen’s huts
etc, it is usually difficult to get a good and reliable safety connection to earth. However, by law
it is obligated to make sure that a person can use an inverter or mobile generator safely. If the
inverter is mounted inside vehicle/unit, and one goes to work outside the vehicle/unit with the
connected 110/230VAC equipment, then it is mandatory to mount an insulation monitoring
device. An RCD (not any type!) will not meet! When an accident occurs because an insulation
monitoring device isn’t mounted in the system, it has serious consequences. In these situations,
always mount an insulation monitoring device from our ISO-series between de inverter and
equipment. For more info, please visit our website www.xenteq.nl. he law applies to all
vehicles/mobile units that are use professionally. Caravans, mobile homes etc. are excluded
from this law, however the circumstances are identical.

5. IN USE
Check that the cables are mounted correctly. Never use the inverter when the cables are
damaged.Set the power switch to “ON” position.
A warm housing is normal when the inverter is operating.
I you will not be using the inverter or a signi icant period (during winter storage or example), we
recommend disconnecting it rom the battery.
5.1 LED indications （FS series ）

5. USB output
All models have an USB port. Here you can connect your 5Volt users, like mobile phone charger,
directly. The maximum load or this output is 2,1Amp.
5.5 Remote control
I the remote controller CR80 or CRD80 or CRW80 is connected, it is important that the main
switch o the inverter is in the ‘o ’ position. A ter this, the inverter can be switched on and o by
using the remote control.
5.6 LCD display function (optional)
It displays the battery voltage(V), output power(W) , battery capacity( Ah), lower voltage
protection, over voltage protection, over load protetcion, over temperature protection.
5.7 Fan
The an is both temperature- and load controlled. At a certain load level, depending per model,
the an will switch on automatically. Also at an internal high temperature the an will switch on
automatically.
What does the inverter consume from the battery?
A quick ormula which gives a global indication o the current draw rom the battery is:
Watt : voltage = current draw per hour
Example: a 1500Watt inverter in 12Volt consumes at ull load:
1500W : 12V = 125Amp. per hour. Has the inverter delivered this power or 5 minutes, then
the current draw rom the battery is about 10Amp per hour.
Remark: when a 1500Watt inverter delivers a power o 600Watt, then it consumes also only
600Watt rom the battery.

6.1 Pre-warning (buzzer)
I the input voltage is becoming low, the inverter will emit an acoustic signal as a warning.
6.2 Low voltage protection.
I , a ter the pre-warning, the input voltage still drops urther, the low voltage protection will
eventually take e ect. The 230VAC output is shut down and the red indicator ‘ ault’ will light.
The buzzer will also continue to sound.
I the input voltage has risen again su iciently, the inverter will automatically restart.
6.3 Over voltage protection
I the input voltage rises too high, the overvoltage protection will come into e ect. The 230VAC
output is shut down and the red ‘ ault’ LED lights up. I the input voltage has dropped su iciently,
the inverter will automatically restart.

Important
he maximum input voltage that the inverter can tolerate is 16 Volts/32Volts. If the voltage that
is supplied is higher than this, then the inverter will break. In this case the repair costs are not
covered by warranty.
6.4 Temperature protection
If the cooling provided by the fan is insufficient, the temperature protection will be activated. The
inverter will shut down the110/ 230VAC output and the red ‘fault’ indicator will light. Once the
inverter has cooled down sufficiently, it will restart automatically.
6.5 Short-circuit on the output
The inverter will switch off the 110/230VAC output voltage if there is a short-circuit of the output.
During this protection, the red ‘fault’ led will flash slowly. The inverter will restart automatically,
once the problem has been resolved.
6.6 Overload protection
The inverter will shut down the 110/230VAC output if the requested power on the output is higher
than the continuous power of the inverter. The red ‘fault’ indicator will flash slowly. The inverter
will restart automatically, once the problem has been resolved.
Important
he overload protection only works with the maximum power and not with the surge power. If
the surge power of the inverter is exceeded then the inverter will break! In this case the repair
costs are not covered by warranty.
