1 GENERAL INFORMATION
The MASTERVOLT Mass Systemswitch is the heart of the
AC installation. It is designed to take over manual
switching between three different power sources. The
Mass Systemswitch automatically transfers the available
AC power source to the right outputs. Automatic switching
between the power sources doesn’t only offer you more
comfort; it also improves the safety on board. The
switching between the power sources, which is done by
means of relays, assures that no short-circuiting will occur.
The status of the Mass Systemswitch can be monitored by
means of a Mastervolt remote control panel. The Mass
Systemswitch is also compatible to be used in the
MasterBus network: a decentralized data network, giving
you full control over the entire electrical installation.

3 HOW IT WORKS
3.1 SOURCE PRIORITY
The Mass Systemswitch switches the right AC power
source to the output(s). Therefore the Mass Systemswitch
is equipped with a source priority. If more than one AC
power source is available, the source with the highest
priority is switched to the output(s).
See figure 1. The generator input has the highest priority:
when generator power is available, all outputs (except the
inverter only output) are supplied by the generator. Power
on the shore input and/or the inverter input will be denied
even when they are available.
The shore input has the second priority. If there is no
generator power available, shore power will be transferred
to the power output and the short break output. Power on
the inverter input will be denied.
The lowest priority is assigned to the inverter. AC power
on the inverter input is transferred to the short break
output only when no other power source is available.
3.2 AC INPUTS
Three AC-sources can be connected to the Mass
Systemswitch:
Inverter power (IN3)
Shore power (IN2)
Generator power (IN1)
3.2.1 Only inverter power available
When there is no AC power available on the generator
input or the shore input, power from the inverter input is
transferred to the short break output only. The power
output and the generator only output are unavailable now.
The Mass Systemswitch is in a neutral state and
consumes no energy itself.
3.2.2 Shore power available
When there is no generator power available but AC power
is available on the shore input, the Mass Systemswitch will
supply both the power output and the Short break output
with AC power from the shore input. The generator only
output is unavailable now.
Figure 1: principle schematics of the Mass Systemswitch
3.2.3 Generator power available
When the generator is started, a control circuit samples its
output voltage and frequency. Only when both are within
allowed limits for approximately 10 seconds, the Mass
Systemswitch transfers the power from the generator input
to all outputs (except for the inverter only output).
Too low generator frequency and voltage may cause
damage to both the generator and the connected load.
Therefore AC power on the generator input is continuously
checked by a control circuit. If the generator frequency or
voltage is too low, generator power is immediately cut off
from the load.
The 10 seconds time delay provides an ‘easy start up’ for
the generator. This increases the generator’s lifetime.
3.3 AC OUTPUTS
The Mass Systemswitch has the following AC-outputs:
Inverter only output
Short break output
Power output
Generator only output

3.3.1 Inverter only output (no break)
The Inverter only output is directly powered by the inverter.
This means that this output will never be transferred to one
of the other AC sources. Critical loads, like a computer or
navigations equipment which are sensitive for voltage
drops, should be connected to this output.
3.3.2 Short break output
The Short break output is transferred between the
generator input, shore input and inverter input, depending
on the availability. In principle, AC-power is always
available on this output.
CAUTION!
During transfer between the AC inputs, users
are not supplied with power for a short time.
Because of this, computers etc. connected to
this output might lose data.
Due to the source priority, this output is supplied by shore
power if available. And also, if generator power is
available, this output will be supplied by the generator
input. This means that the generator input has a higher
priority than shore input and the shore input has a higher
priority than inverter input. This preferent behaviour is not
always wanted. For instance if the external shore power
breaker is only 4A, it is not possible to power the whole
electrical system at the same time. It is however possible
to override this preference manually by means of the load
on inverter mode. See section 3.5 for additional
information.
3.3.3 Power output
Depending on its availability, the power output is powered
by the generator input or the shore input. The generator is
the highest in priority and therefore overrules the shore
power. Medium power loads like the battery charger must
be connected to this output.
3.3.4 Generator only output
Finally the generator only output is powered by the
generator only. Larger loads like a water maker or an
electric cooking appliance should be connected to this
output.

3.4.1 Remote control panel (optional)
For remote operation Mastervolt offers a wide range of
intelligent remote control panels that can be connected to
the Mass Systemswitch, giving you a status overview of
the available AC-power sources. Besides when a remote
control panel is applied, a very useful feature of the Mass
Systemswitch can be used: the load on inverter mode.

3.4.2 MasterBus (optional)
The Mass Systemswitch is compatible with the MasterBus
network: a fully decentralized data network for
communication between Mastervolt devices such as the
inverter, battery charger, generator, batteries and many
more. See section 5 for details.
3.5 LOAD ON INVERTER MODE
The Short break output is transferred between the
generator input, shore input and inverter input, depending
on its availability. However, to prevent the generator from
an overload situation or to prevent the shore fuse from
tripping, the load that is connected to the Short break
output can be switched either manually or automatically
from the generator or shore power to the output of the
inverter. We call this the “load on inverter mode” or the
“force to inverter mode”.
or shore
Figure 4: Load on inverter mode is ON, while power from
the generator or the shore is available
or Power
3.6 AUTOMATIC LOAD ON INVERTER MODE
It is also possible to toggle the load on inverter mode
automatically. Then the load on inverter mode will be
switched ON when the current on the shore input or the
generator input exceeds a predefined set point. Then we
call it the “automatic load on inverter mode” or the
“automatic force to inverter mode”.
When the load on inverter mode is switched OFF (figure
3), the Mass Systemswitch is in normal state. This means
that the Short break output is transferred between the
generator input, shore input and inverter input, depending
on the availability.
When the load on inverter mode is switched ON (figure 4),
power from the generator or the shore can no longer be
used to supply the Short break output. The Short break
output will only be supplied by the inverter. See the
manual of the remote operation panel to toggle the load on
inverter mode manually.
or shore
Figure 3: Load on inverter mode is OFF, while power from
the generator or the shore is available
or Power
3.6.1 Traditional remote control panel
If a traditional remote control panel is applied, the
“automatic load on inverter mode” can be triggered by:
- The generator current (delayed)
- The shore current (not delayed)
To adjust the settings of the automatic load on inverter
mode refer to ADVANCED A-menu of the manual of the
remote operation panel.
3.6.2 MasterBus
If the Mass Systemswitch is controlled by MasterBus,
operation of the “automatic load on inverter mode” can be
programmed by means of an event-based command. See
section 6.3 for details. Refer to the manual of the
MasterBus remote panel for details about programming of
event-based commands.
3.6.3 Example
See figure 5. A coffee machine is switched on, causing an
extra load on the shore/generator. When the total load that
is connected to the shore or the generator exceeds its
maximum current level, first a time delay is triggered. After
this delay time the automatic load on inverter mode will be
activated: a part of the total load is switched from the
generator/ shore to the AC output of the inverter. When
the automatic load on inverter mode is activated, it is
switched off again when the adjusted time has elapsed.

WARNING
External fuses and earth leakage switches
must be integrated in the wiring of all inputs
and outputs of the Mass Systemswitch.
4.1 GENERAL
During installation and commissioning of the Mass
Systemswitch the Safety Guidelines and Measurements
are applicable at all times. See section 2 of this manual.
After unpacking, check the Mass Systemswitch for
possible damage. Do not use the Mass Systemswitch if
the cabinet is damaged.
4.2 ENVIRONMENT
Obey the following stipulations during installation:
The Mass Systemswitch is designed for indoor use
only.
Humidity: 0-95% non-condensing.
Mount the Mass Systemswitch on a solid surface, with
the connecting cables downwards.
Figure 6: mounting of the cabinet
4.5 OPENING THE CONNECTION COMPARTMENT
See figure 7. Steps:
1. Loosen the two Phillips screws A and B that secure
the front cover plate two turns.
2. Slide the front cover plate from the cabinet (C)
(downwards).
3. The terminals and cable glands are now accessible.
Note: If necessary you can also remove the gland plate
by loosening screws D, E and F. Read section 4.13
carefully to close the connection compartment
again.
4.3 TOOLS REQUIRED FOR INSTALLATION
We recommend as a minimum tool kit:
Flat blade screw driver 1.0 x 4.0 mm to fix the screw
terminals of the AC wiring.
Flat blade screw driver 0.6 x 3.5 mm for connection of
the remote panel.
Tools to fix the screws / bolts (Ø 6mm) with plugs to
mount the cabinets to a surface.
Phillips screw driver number 2 to open the connection
area of the Mass Systemswitch.
4.4 MOUNTING OF THE CABINET
Take the following steps to mount the cabinet:
1. Determine for the four mounting spots on the basis of
the outline drawings (section 6.2 Dimensions).
2. Fix the screws (Ø 6mm) into the surface but do not
tighten them entirely.
3. Place the housing over the screws.
4. Fix the housing by fastening the screws securely.
Always close the connection compartment prior to
commissioning of the Mass Systemswitch.
4.6 WIRE CROSS SECTION
For a safe installation the correct wire cross section must
be applied. Don’t use a cross section that is smaller than
indicated. See table below to select the appropriate cross
section for the AC wiring:
WARNING
Use cables with the right wire cross section!
Under-sized wires and/or loose connections can cause
dangerous overheating of the wires and/or terminals.
Therefore use the proper size and tighten all connections
well, in order to limit transition resistance as far as
possible.

4.7 GROUND CONNECTIONS
The ground wire offers protection only if the cabinet of the
Mass Systemswitch is connected to the system ground.
Connect the inverter’s earth terminal (PE) to the hull or the
chassis.
For safety reasons it is very important that all ground
connections of the power sources and power consumers
are connected to the central ground connection of the
ship/vehicle. Improper ground connections might lead to
life threatening situations. A reliable ground connection is
made by connecting the sources and the consumers to the
ground terminal (ref. 10) of the Mass Systemswitch. This
ground terminal must be connected to the central ground
connection of the ship, which is connected to the hull of
the ship.
When the ship lies in sea water (salt) while using shore
power, corrosion can occur. This corrosion is caused by
potential differences between shore ground and ships
ground. Using an isolation transformer will solve this
problem. Mastervolt can provide a suitable transformer.
4.8 WIRING
The wiring is connected inside the connection
compartment. If necessary, the cabling can be fed from
the top to the bottom side of the cabinet along the back of
the cabinet. Always feed the wiring through the cable
glands of the cabinet, and then connect the wiring to the
terminals.
Fix the phase line wire to the L terminal, the neutral wires
to the N terminal. Fix the ground wires (PE) to the ground
terminal bus bar (ref. 10).

4.12 MASTERBUS (OPTIONAL)
See figure 8. The Mass Systemswitch can be connected to
the MasterBus network by means of the two data ports
(figure 8, reference 11). See also section 5.3 for details.
Note: For remote operation of the Mass Systemswitch
you have to choose between either the MasterBus
network or a remote panel as described in section
4.11. You cannot use both.
4.13 COMMISSIONING AFTER INSTALLATION
Follow the steps described below to switch on the Mass
Systemswitch.
1. Tighten all cable glands to ensure the pull relief.
2. Check all wiring and connections.
3. Close the front cover plate of the connection
compartment.
Note: If the gland plate was removed during installation,
be sure to slide back the cover plate before you fix
screws D and E (see figure 7).
4. Switch on the AC power sources.
4.13.1 MasterBus (optional)
During first commissioning the Mass Systemswitch will be
recognized by the MasterBus network automatically. The
remote control panel of the MasterBus network will
indicate that a new device was found.
The factory settings of the Mass Systemswitch are optimal
for most installations. In some applications however, it is
desirable to change settings. See section 6.3 for an
overview of all available settings. Refer to the user manual
of the remote control panel to change these settings.
Note: Some settings can only be changed via the
MasterBus interface. If changes were made to the
factory settings, all LEDs will flash three times
during powering of the Mass Systemswitch, i.e.
when either generator or shore input comes
available or when the MasterBus is powered.
4.14 DECOMMISSIONING
If it is necessary to put the Mass Systemswitch out of
operation, follow the instructions in order of succession as
described below:
1. Switch off all loads.
2. Switch off the AC power sources. These power
sources should be secured against unexpected and
unintended switching on.
3. Open the connection compartment of the Mass
Systemswitch (see paragraph 4.5).
4. Check with a suitable voltage meter whether the
inputs and the outputs of the Mass Systemswitch are
voltage free.
5. Disconnect all wiring.
Now the Mass Systemswitch can be demounted in a safe
way.
4.15 STORAGE AND TRANSPORTATION
When not installed, store the Mass Systemswitch in the
original packing, in a dry and dust free environment.
Always use the original packing for transportation. Contact
your local Mastervolt Service Centre for further details if
you want to return the apparatus for repair.

5 MASTERBUS
5.1 WHAT IS MASTERBUS?
All devices that are suitable for MasterBus are
marked by the MasterBus symbol.
MasterBus is a fully decentralized data network for
communication between the different Mastervolt system
devices. It is a CAN-bus based communication network
which has proven itself as a reliable bus-system in
automotive applications. MasterBus is used as power
management system for all connected devices, such as
the inverter, battery charger, generator and many more.
This gives the possibility for communication between the
connected devices, for instance to start the generator
when the batteries are low.
MasterBus reduces complexity of electrical systems by
using UTP patch cables. All system components are
simply chained together. Therefore each device is
equipped with two MasterBus data ports. When two or
more devices are connected to each other through these
data ports, they form a local data network, called the
MasterBus. The results are a reduction of material costs
as only a few electrical cables are needed and less
installation time.
5.2 EVENT BASED COMMANDS
With MasterBus each device can be programmed to
initiate an action at another connected device. This is done
by means of event based commands.
Example: if the shore power is almost in overload, the
generator must be started. As the shore power is
measured by the Mass Systemswitch, this device is
considered as the command source. The generator is the
device that should initiate an action (start the generator),
and is therefore considered to be the target. This means
that the Mass Systemswitch must be programmed as
follows:
For central monitoring and control of the connected
devices Mastervolt offers a wide range of panels which
show full status information of your electrical system at a
glance and a push of a button.
New devices can be added to the existing network in a
very easy way by just extending the network. This gives
the MasterBus network a high degree of flexibility for
extended system configuration, not only today, but in the
future as well! Mastervolt also offers several interfaces,
making even non-MasterBus devices suitable to operate in
the MasterBus network.
See section 6.3.4 for the list of events sources and section
6.3.5 for the list of event commands of the Mass System-
switch.
