Installing MOB+ Wireless kill switch
Main Power Switch
Do not touch or cut any existing wires or
electrically conducting components before you
make sure the main voltage switch is OFF. Only
set the main voltage switch to ON after you are
finished cutting and connecting wires.
Make sure that all wires and conductive
connection points are free from corrosion before
connecting any wires.
The function of the kill switch must be tested after
installation to verify that it stops the engine in the
event of an emergency situation.
1-3 A
This is done by submerging the xFOB in water or
walking with the xFOB away from your boat until the
engine stops. The xHUB will then light red and give a
sound signal to indicate a man over board event.
10 - 32 VDC
Max continuous switch load: <5A
Min. Voltage: 7V
-Below this voltage the unit will turn off.
5-pin IP67
Switch position in inactive
mode e.g. engine not running.
Connecting the Power
(10-30 Vdc)
1. Use a test light or a voltmeter to determine the
polarity of the voltage source.
2. Connect the red (+ or positive) wire to the positive
voltage terminal. (If you use the fuse block on the
boat, route the positive connection through the
fuse, as shown on the diagram.)
3. Connect the black (- or ground) wire to the
negative voltage terminal.
4. Install or check the 1-3 A fuse (in the in-line fuse
holder, or on the fuse block of the boat.
5. Use wire hoods suitable for the wire dimension
(20AWG, 0.75mm2) or connection point on the
fuse block.
Use an AGC / 3AG – 1-3 Amp replacement fuse.
If it is necessary to extend the power and ground
wires, use 20 AWG or thicker wire.
You can wire the Power Wires directly to the main
boat battery, or if your boat has an electrical
system, you might be able to wire the Power
Wires to an unused holder on the fuse block. In any
case it should be after the main power switch to avoid
current drainage when the boat is left unattended.
Keep existing kill switch
The switching function inside xHUB is a double throw
relay and can be connected to switch any circuit on
and off, and thus perform the old kill switch function.

MOB+ Wireless Kill Switch can be installed together
with your existing kill switch by connecting it in series
or parallell. If you should connect in series or parallell
depends on your existing kill switch function. The

*The wire connections are the same for the
external kill switch and kill switch mounted in
the throttle casing.
Connecting Signal wires
Yamaha uses «Close to Stop» kill switch principle as
standard. This means that the engine kill switch shorts
circuits to stop the engine.
We recommend to verify this by simply trying to start
the engine(s), whilst the existing kill switch signal
wires are not connected.
It is very important that the MOB+ gets supplied
power from a stable source which is not susceptible to See the user manual for further
voltage drops as if it gets below 7V supply voltage, the instructions.

Installing MOB+ in a metal boat
If your helm is made out of conducting materials the
wireless signals from MOB+ may be degraded. The
amount of signal degradation experienced may vary
from across boats and must be tested for each case.
If the signal is very poor you can install a separate
external antenna outside of your helm to increase the
signal strength. Please contact FELL support at
www.fell.no/support for more information.
Multiple engine configurations
Make sure that all wire connections are waterproof
by using heat shrinkable butt splices or similar when
connecting wires.
If you have multiple engines on your boat and your
boat is already fitted with a kill switch you can connect
the wires as described above to the two existing signal
wires leading to the existing mechanical switch in your
helm or throttle.
Insert cables and ensure the
conducting part of the cable
makes good contact with
the conducting part of the
butt splice.
In some cases the existing kill switch might be a 2
pole or 3 pole switch to switch 1 pair of wires for each
engine separately.
In this case a standard DPST/DPDP relay can be used
as the switch and the control signal to the relay is
wired through the MOB+. Please see the user guide for
Use a crimping plier to
squeeze the conducting part this wiring on www.fellmarine.com/support.
of the butt splice around
the wire.
Make sure all
connections are
waterproof by applying
heat to the end of the butt
splice, which makes it shrink
around the wire.
Some engine brands also offer a diode splitter. This
splitter translates the signal from the single mechanical kill switch into a kill switch signal for multiple
engines and so the MOB+ can be connected in a
standard fashion.
If you have multiple engines and do not have an
existing kill switch, see user manual for this on www.
fellmarine.com/support. Please contact your local
engine retailer or manufacturer for further assistance.
