HOW IT WORKS
8 June 2009 / Mass GI / EN
4 HOW IT WORKS
In order to prevent electrical corrosion of metal parts
on your ship while maintaining the onboard earth, a
separation between the AC shore power and the
onboard AC power is necessary.
As mentioned before, the Mass Isolating
Transformer provides you with this separation. It is
installed in between the AC shore power connection
and the onboard AC loads. If 3.5 kW of shore power
is not sufficient, more Mass GI’s can be connected in
parallel to increase the power up to 14 kW
maximum. With the Mass GI’s in parallel, power
conversion will be divided between the units. See
chapter 9 for more details.
4.1 MasterBus communication
The Mass GI communicates via the MasterBus
network. This network is used for remote control and
remote (alarm) monitoring of the Mass GI, for
configuration (in parallel) and for communication
with other system devices. See chapters 6 and 7 for
more information.
4.2 Protection
The Mass GI is protected against overload, peak
current, short circuit and high temperature. See
section 5.1 for LED indications when a protection
comes into effect.
4.2.1 Overload protection
The Mass GI is equipped with an integrated fuse
which limits the input current to 16A. This fuse will
switch the Mass GI to Stand by in overload
situations and trigger the MasterBus alarm.
4.2.2 Second overload protection
The Mass GI is protected by a 20AT fuse as well.
This fuse switches off the Mass GI input, there will
be no MasterBus alarm.
To correct the situation at the Mass GI 3.5, proceed
as follows:
1. Move the main switch of the Mass GI to the
Standby position.
2. Disconnect the Mass GI from any power
source. Disconnect all loads from the Mass GI.
3. Investigate the cause of failure of the thermal
fuse like overload or short-circuits.
4. Refer to section 8.7 to open the connection
compartment.
5. Wait for at least two minutes and then reset the
20AT fuse by pushing the button inside the
connection compartment, see figure 1 ref.10.
6. Close the connection compartment again.
7. Connect the Mass GI to the power sources.
8. Switch on the Mass GI.
If the fuse trips again in short time, please contact
your Mastervolt supplier for service.
At the Mass GI 7.0 (MultiTap) the 20AT fuse is
located inside the device. Therefore corrections can
only be performed by qualified technicians.
4.2.3 Peak current limitation
The Mass GI is automatically protected against a
peak current during a short period.
4.2.4 Short circuit protection
The Mass GI is protected against a short circuit
situation by a fuse which trips when during 1 second
short circuit conditions are met. In case of short
circuit, the Mass GI switches to Standby, the short
circuit LED illuminates and the MasterBus alarm is
triggered.
4.2.5 Thermal protection
The Mass GI is protected against high temperature
by 3 integrated thermal fuses. If one of these fuses
trips, the Mass GI will switch to Stand by, the high
temperature LED illuminates and the MasterBus
alarm is triggered.
4.2.6 MasterBus power supply protection
The MasterBus power supply (internal aux power
supply) is protected by means of a 1A fuse.

OPERATION
EN / Mass GI / June 2009 9
5 OPERATION
The Mass GI can be activated by switching the main
switch (figure 1, ref. 1) to the “ON” position. When no
error is present, the green ON LED illuminates after
this. The Mass GI will then generate an AC output
voltage. Move the switch to the Standby position to
switch off the Mass GI. In standby the Mass GI
remains connected to the AC mains!
5.1 Resetting the Mass GI
When the Mass GI is in failure mode it can be reset
in two ways:
1. By switching it Off and On again using the
main switch (figure 1 ref. 1).
2. By using the MasterBus function Restart
(section 7.1).
5.2 Maintenance
No specific maintenance is required. If necessary,
use a soft clean cloth to clean the Mass GI. Never
use any liquids, acids and/or scourers.
For reliable and optimum function examine your
electrical installation on a regular base, at least once
a year. Defects such as loose connections, burnt
wiring etc. must be corrected immediately.
5.3 LED indicators

MASTERBUS
10 June 2009 / Mass GI / EN
6 MASTERBUS
6.1 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 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 enables
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. The results are a
reduction of material costs as only a few electrical
cables are needed and less installation time.
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. All
monitoring panels can be used for monitoring,
control and configuration of all connected MasterBus
devices.
New devices can be added to the existing network in
a very easy way by just extending the network. With
this the MasterBus network offers 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.
For direct communication between the MasterBus
network and a product which is not from Mastervolt,
the Modbus interface is recommended.
CAUTION: Never connect a non-
MasterBus device to the MasterBus
network directly! This will void warranty of
all MasterBus devices connected.
The event configuration of the Mass GI as target and
as source is described in chapter 7 of this manual.

MASTERBUS
EN / Mass GI / June 2009 11
6.2 How to set up a MasterBus network
Every device suitable for the MasterBus network is
equipped with two data ports. When two or more
devices are connected by these ports, they form a
local data network, called the MasterBus.
Keep the following rules in mind:
Figure 4
Figure 5
Figure 6
Figure 7
Figure 8
Connections between the devices are made by
standard straight UTP patch cables. Mastervolt
can supply these cables. These cables are also
commonly available at computer supply stores.
OK
1-8
As with all high speed data networks, MasterBus
needs a terminating device on both ends of the
network.
Terminating
device
Terminating
device
OK
Do not make T-connections in the network.
Do not make ring networks
The connected devices provide the electric
power for the network. At least one device in the
network should have powering capabilities (see
specifications).
One powering device can power up to three non-
powering devices. As all powering devices are
galvanically isolated, multiple powering devices
are allowed.

from the top to the bottom side of the cabinet along
the back of the cabinet. Always feed the wiring
through the cable glands (fig.1 ref. 5) of the cabinet,
and then connect the wiring to the terminals.
Cut the wiring as shown in figure 11. Strip the
conductors for 8 mm.
The diameter of the outer isolation must be
between 10 and 14 mm to fit in the cable
glands correctly enabling strain relieve.
Figure 11: Wiring
WARNING
Never connect Earth (input)
to Protective Earth (output)!
For safe installation it is necessary to:
• Connect both the earth (PE/GND) and the
neutral (N) of the AC output of the Mass GI to the
grounding point, fig. 16. This grounding point must
be connected to the central ground connection of the
ship, which is connected to the hull of the ship.
• Integrate a Residual Current Device (RCD) in
wiring of the AC output.
Refer to local applicable regulations on these issues.
8.9 Connection
Steps:
1. Connect the AC load to the AC output (fig.16).
2. Connect the incoming shore power via a circuit
breaker to the AC input (fig.15). Phase line to L,
Neutral to N, and Ground to PE/GND.
8.10 Commissioning after installation
1. Tighten all cable glands (fig. 1, ref. 5) to ensure
the strain relief.
2. Check all wiring and connections.
3. Close the front cover plate of the connection
compartment. Beware that the cabling does not
obstruct the cooling fan (fig. 1, ref.11) and air flow.
Now the Mass GI is ready for operation!

TWO TO FOUR MASS GI’S IN PARALLEL (ADDITIONAL INFO)
16 June 2009 / Mass GI / EN
9 TWO TO FOUR MASS GI’S IN PARALLEL (ADDITIONAL INFO)
For shore connections of more than 16A (32A),
multiple Mass GIs can be used in parallel (maximum
four Mass GI 3.5 or two Mass GI 7.0/ Mass GI 7.0
MultiTap).
CAUTION!
In parallel, all inputs must be connected to
the same phase!
WARNING!
Never connect the output(s) to any other
power source!
See figure 12 for installation. Steps:
1. Connect the MasterBus cable between the
communication ports on the Mass GI’s.
2. Connect the AC load to the AC output on the
units (figure 16).
3. Connect the incoming shore power to the AC
input on your Mass GI’s. Phase line to L, Neutral to
N, and Ground to PE (figure 17).
9.1 Installation of four Mass GI’s in parallel
(Mass GI 3.5 only)
Extra materials needed for 4 Mass GI’s: 16 screws
(with rings and plugs), size m8. Use suiting materials
to carry the weight of the Mass GI.
If you have more than four Mass GI’s to put in
parallel, you need to install two groups, using
manual setup.
To achieve maximum performance all input
and output wiring must be of equal length.
For more than two Mass GI’s we
recommend a star configuration like shown
in figure 12.
Figure 12: Parallel connection of four Mass GI 3.5 in one group
9.2 Parallel operation in one group
In one group all Mass GIs in the MasterBus network
run in parallel. Parallel configuration is done
automatically via MasterBus communication. When
two, three or four units are detected in a MasterBus
network, the system assumes that these operate in
parallel.
9.3 Multiple groups of Mass GI(s) in parallel
With more than four Mass GI’s in parallel you need
more than one group. For example 8 Mass GI’s can
be configured as two groups of four Mass GIs
running in parallel. In this situation additional
configuration of the system is required. Per group of
GI’s one of the units needs to be assigned the status
of Master. In “Configuration” > “Parallel” one should
select “Master”. After this action the required number
of Mass GIs can be selected to run in parallel to the
Master via selection in Product 1, Product 2, Product
3 and Product 4. Note Product 1 is the product that
was selected as Master.
Rename Mass GIs before configuring
multiple groups of GIs. For example
“Transformer 1” etc.
If the automatic paralleling of Mass GI’s is
not desirable, select “Master” on the units
in parallel configuration and do not select
additional products to run in parallel. This
effectively creates single units that will not
switch to parallel mode automatically.

9.4 Safety devices in parallel configuration
The figure below shows the recommended safety
devices and their rates for parallel configuration. At
the input only one circuit breaker is sufficient, given
the fuse is rated according to the total input current.
At the output, each Mass GI shall be provided with a
circuit breaker and the common output must contain
a residual current device suitable for the total output
current.
