SAFETY GUIDELINES AND MEASURES
410000013074_01 / Lithium-ion Battery MLI-E / EN
1 SAFETY GUIDELINES AND MEASURES
1.1 General rules
Observe these instructions and keep them
located near the Li-ion Battery for future
reference.
Work on the Li-ion Battery should be carried out
by qualified personnel only.
While working on the Li-ion Battery wear
protective eye-glasses and clothing.
Any uncovered battery material such as
electrolyte or powder on the skin or in the eyes
must be flushed with plenty of clean water
immediately. Then seek medical assistance.
Spillages on clothing should be rinsed out with
water.
Explosion and fire hazard. Terminals of the Li-
ion Battery are always alive; therefore do not
place items or tools on the Li-ion Battery. Avoid
short circuits, too deep discharges and too high
charge currents. Use insulated tools. Do not
wear any metallic items such as watches,
bracelets, et cetera. In case of fire, you must
use a type D, foam or CO2fire extinguisher.
Never try to open or dismantle the Li-ion
Battery. Electrolyte is very corrosive. In normal
working conditions contact with the electrolyte is
impossible. If the battery casing is damaged do
not touch the exposed electrolyte or powder
because it is corrosive.
Li-ion Batteries are heavy. If involved in an
accident they can become a projectile! Ensure
adequate and secure mounting and always use
suitable handling equipment for transportation.
Handle with care because Li-ion Batteries are
sensitive to mechanical shock.
Li-ion batteries can be charged with a voltage
up to 14.6 V. On the other hand, Li-ion batteries
can be discharged down to 11.0 V. Note that
this voltage range (11.0-14.6V) is larger than
you may expect from other battery types such
as lead-acid batteries. Be aware that these
voltages may exceed the permitted voltages of
the connected load(s). Therefore appropriate
measures must be taken to avoid damage to
the connected load(s).
If charged after the Li-ion battery was
discharged below the Discharge cut-off voltage,
or when the Li-ion battery is damaged or
overcharged, the Li-ion battery can release a
harmful mixture of gasses such as phosphate.
Non-compliance with operating instructions, repairs
made with other than original parts, or repairs made
without authorization render the warranty void.
1.2 Transportation warnings
The Li-ion battery must be transported in its
original or equivalent package and in an upright
position.
If the battery is in its package, use soft slings to
avoid damage.
Do not stand below a Li-ion battery when it is
hoisted.
Never lift the battery at the terminals, only lift
the battery at the handles.
Batteries are tested according to UN Handbook of Tests
and Criteria, part III, sub section 38.3
(ST/SG/AC.10/11/Rev.5).
For transport the batteries belong to the category UN3480,
Class 9, Packaging Group II and have to be transported
according to this regulation. This means that for land and
sea transport (ADR, RID & IMDG) they have to be packed
according to packaging instruction P903 and for air
transport (IATA) according to packaging instruction P965.
The original packaging satisfies these instructions.
1.3 Disposal of li-ion batteries
Batteries marked with the recycling symbol must be
processed via a recognized recycling agency. By
agreement, they may be returned to the manufacturer.
Batteries must not be mixed with domestic or industrial
waste.

OPERATION
EN / Lithium-ion Battery MLI-E / 10000013074_01 7
3 OPERATION
3.1 Charging and discharging
Use the Li-ion Battery within the specifications as stated in
chapter 10.
3.2 Cell management system
The Mastervolt Li-ion battery consists of a pack of battery
cells. As with all kind of batteries, there is always some
kind of unbalance present between the individual cells.
During charging of an unbalanced battery pack, one or
more cells will reach the maximum state of charge before
the other cells. During discharge the cells that are not fully
charged will be depleted prior to the other cells, causing
early undervoltage shutdown of the pack. Normally
spoken, these early charge and discharge limits reduce
the usable capacity of the battery and will shorten the
expected lifetime of the pack. To avoid this kind of
premature failure, the Mastervolt Li-ion battery is provided
with a Cell Management System (BMS). With this system,
each cell is conditioned individually.
Features of the Cell Management System:
Balancing between the different cells. Normally, cells
in a series string receive identical currents. With the
Cell Management System current from stronger cells
will be transferred to the weaker cells during the
charging/ discharging process and idle mode;
Protection of each separate cell from under- and over-
charging by voltage monitoring of each individual cell;
Prevention of too deep battery discharges;
Monitoring of temperature. Each separate cell as well
as the external temperature of the battery pack is
being monitored;
Communication with Mastervolt charge devices to
maximize safety and performance;
Pre warnings when the state of charge is becoming
low.
WARNING
Before using the Li-ion battery, it must be
installed and commissioned in accordance with
the instructions stated in chapters 4 and 5 of
this manual!
3.3 Safety features
Under- and over-charging and excessive temperatures
may lead to permanent damage to the Li-ion battery and
even to dangerous situations. Therefore the Li-ion battery
is provided with several advanced safety features.
WARNING
Alarms and warnings generated by the Li-ion
battery should not be neglected. It is the user’s
responsibility to take adequate measures.
There are two levels of protection:
Warning: The orange LED of the MLI-E will be lit.
Alarm: The red LED of the MLI-E will be lit. This is an
“emergency stop” of the battery. The battery will
disconnect itself from the system.
3.4 MasterBus functionality
Refer to chapter 6 for advanced MasterBus functionality.
The Li-ion battery is not able to power the MasterBus
network. A proper amount of powering devices should be
placed in the MasterBus network.
CAUTION!
Make sure to place the MLI-E batteries on the
end of a MasterBus network.

6.1 Basic NMEA Components and how to use them
1 Power Tee - Connects to Power Source
The power tee connects the network to a power source. When connecting to a power source, remember to connect the
positive wire to either an ignition switch or a standalone switch. This will ensure that your NMEA 2000 network is not draining
power when not in use. The power tee is easily identified by the red tee with yellow couplers on both sides.
2 Backbone Cable - Connects the Tees
Backbone cables connect tee connectors to one another or to a power tee. Backbone cables are used when the power tee
and device are at different locations or when multiple devices are at different locations along the network backbone. Ancor
backbone cables have yellow couplers and are made from a heavier gauge wire than Ancor drop cables to help reduce
voltage drop along the network backbone. Ancor offers backbone cables in 0.5m (1.6ft), 2m (6.5ft), 5m (16ft) and 10m (32ft)
lengths.
Figure 12: Simple NMEA Network Example

COMMUNICATION
EN / Lithium-ion Battery MLI-E / 10000013074_01 15
3 Tee Connector - A point for breakoff connecting
Tee connectors create a point within the network backbone to add a drop cable and device. The network backbone will
always be linear and may consist of any combination of backbone cables, tee connectors and a power tee. The yellow
coupler on the tee connects to the yellow coupler on either side of the power tee or backbone cable. The black coupler on the
tee connects to the drop cable. Ancor offers single, two way and four way tee connectors.
4 Drop Cable - Connects to the Tees of the Backbone
Drop cables connect the network backbone to NMEA 2000 devices. The drop cable connects the tee connectors’ black
coupler to the NMEA 2000 device. Ancor drop cables have black couplers and are made from a lighter gauge wire than Ancor
backbone cables to allow easier wire routing from the network backbone to the NMEA 2000 device. Ancor offers drop cables
in 0.5m (1.6ft), 1m (3.3ft), 2m (6.5ft) and 5m (16ft) lengths.
5 NMEA 2000 device
Any electronic device with a NMEA 2000 connection and a NMEA 2000 communication protocol. NMEA 2000 Certified
devices and Approved components are strongly recommended as they ensure compatibility and proper data exchange.
Common NMEA 2000 devices include chartplotters, engine instruments, GPS units and more.
6 Terminating Resistors - Terminating the connection
Terminators are required on each end of the network backbone to ensure signal integrity. The yellow coupler on the
terminator will connect to the yellow coupler on a tee connector. Ancor terminators are offered with either a male or female
coupler to attach to either side of a tee connector at the end of a backbone.
6.1.1 Adding additional devices
1. To add another NMEA 2000 device to the network
created in the instructions above, start by determining
where you will need to place a drop cable for the
device.
2. Once you have determined this location, disconnect
the backbone at the closest backbone connection and
add in a tee connector. When connecting several drop
cables in a similar location use an Ancor 2-way or 4-
way tee connector.
3. Reconnect the backbone connection(s) with the new
tee connector in place.
4. Connect the drop cable to the black coupler on the tee
and then connect to the new NMEA 2000 device.
CAUTION!
Always make sure the NMEA 2000 network
has ONLY two total terminating resistors (one
at each end of the backbone) and is connected
to a power source with a power tee in ONLY
one location.
6.1.2 Network limits
Total length of the NMEA 2000 network cannot
exceed 100 meters (328 feet)
Each drop cable cannot exceed 6 meters (19.7 feet)
Total length of all drop cables within the network
cannot exceed 78 meters (256 feet)
Maximum number of connected devices cannot
exceed 30.

6.2 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 facilitates communication between the connected
devices, for instance to start the generator when the
batteries are low.
MasterBus reduces complexity of electrical systems by
using less cables. All system components are simply
chained together. For this purpose every MasterBus
device has been equipped with two MasterBus data ports.
When two or more devices are connected through these
data ports, they become a local data network, called the
MasterBus. The results are a reduction of installation costs
as only a few electrical cables and less installation time
are needed.
For central monitoring and control of the connected
devices, Mastervolt offers the EasyView 5 remote control
panel 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 makes
the MasterBus a highly flexible network for extended
system configuration, today and in the future.
Mastervolt also offers several interface units, 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, several interfaces are available. Example is
the MasterBus Modbus interface.
CAUTION!
Never connect a non-MasterBus device to the
MasterBus network directly! This will void
warranty of all MasterBus devices connected.
6.3 How to set up a MasterBus network
Every device that is suitable for the MasterBus network is
equipped with two data ports. When two or more devices
are connected to each other through these ports, they
form a local data network, called the MasterBus.
Keep the following rules in mind:
Figure 13: UTP patch cable
Figure 14: Two Terminators
As with all high speed data networks, MasterBus
needs a terminating device on both ends of the
network.
OK
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.

6.4 Monitoring and Configuration of the Li-ion
battery
To monitor the MLI-E values on a MasterBus network an
Easyview 5 remote control panel needs to be installed. To
configure the MLI-E in a MasterBus network a MasterBus-
USB interface connected to a PC with MasterAdjust
software is also needed. The available menu pages are
Monitoring, Alarms and Events.
The Li-ion battery can also be monitored by means of an
NMEA display.
