3.0 Mounting the Battery
10 Xantrex Lithium-ion Battery Owner's Guide
Map out the location of your batteries
with a simple wire diagram for pre-
planning purposes. The cables
between the batteries and all other
components should be as short as
possible. Having shorter cables will
reduce the voltage drop throughout
the system allowing better
performance and reliability of your
power system.
cIn a parallel installation, the
battery cables between the parallel
batteries must be the same length to
reduce voltage differences between
the batteries.
nInclude all the components on
your wire diagram, specifically
DC protection devices and
major connection points.
nAlso take into consideration
where the other components
will be installed in relation to
the batteries to account for
cable bending as well as ease
of access to components once
they are installed
3.0 Mounting the Battery
WARNING
HEAVY EQUIPMENT
Always use proper lifting techniques during handling and
installation. A two-person lift may be required to prevent personal
injury.
Failure to follow these instructions can result in death, serious
injury, or equipment damage
To mount the Xantrex Battery:
1. Select an appropriate mounting location inside your
vehicle or vessel.
2. Mount the battery upright (top label pointing up as shown
in the cover page).
a. On a horizontal surface such as the floor (ideal)
b. On a horizontal surface on battery racks
3. Alternatively, you can mount sideways with the side label
pointing up.
4. Ensure that the battery is secured according to local
regulations. For securing a marine battery according to
local regulations, refer to 33CFR 183.420 and ABYC E-10
- 10.7. For securing an RV battery according to local

Figure 4 Approved Orientations
NOTICE
GENERAL PRECAUTION
Do not mount the Xantrex Battery in an area subject to high
vibration or physical shock.
Failure to follow these instructions may reduce the life of the
battery.

4.0 Placing the Battery Safely
975-1044-01-01 11
4.0 Placing the Battery Safely
Position the battery and devices that will connect to the battery
in a way that the battery cables avoid sharp bends. Follow the
bend radius recommendation below. Aside from battery cables,
it is good practice to apply the same bend radius to
communication cables as well.
Figure 5 Bending Radius
TIPS:
nA cable’s bend radius should be no less than eight (8)
times the outside diameter of the cable used. More
specific details can be supplied by the cable and wire
manufacturer for your specific scenario.
nAs it is not normally possible to have such a large bend
radius in many installations due to limited space, getting
as large a bend radius in as much as the space allows is
ideal.
5.0 Installing DC Protections
for the Battery
Battery protection devices such as properly rated DC fuses,
DCdisconnect devices, or DC breakers are required to protect
the battery from overcurrent scenarios. Here are some basic
definitions:
n(A) DC fuses are fuses specifically rated for DC and
come with their own fuseholders. Fuses are replaced
when they blow. Fuses are installed together with a DC
disconnect device. See Figure 6 below.
n(B) DC disconnect devices are binary switches that are
either open (OFF) or closed (ON) to stop or allow DC
current to flow, respectively.
n(C) DCcircuit breakers or simply DCbreakers are arc-
reducing electromechanical switches that trip (open fast)
with overcurrent and are reset (closed) manually. See
Figure 7 below.
A B C
IMPORTANT:
nThe battery protection device should be installed inline
with the positive cable of the battery.
nIdeally the protection device should be installed as close
as practicably possible to the positive terminals of the
battery.
ncDo not manually operate these protection devices
while there are active DCloads and/or charging devices
connected to the DC bus. For example, an engine
mounted alternator that is connected to the DC bus may
sustain damage if the protection devices are closed and
opened while in operation. Turn off the engine first.

Cables
WARNING
FIRE HAZARD
Use only stranded, copper wire rated minimum 75 °C (105 °C for
marine installations). Make sure all DC connections to the
Rebling connector terminals (see Figure 9 below) are tight to a
torque of 60±3in-lb (or 6.7±0.35N-m) of force. Loose
connections will overheat. Too much torque may crack the
Rebling connector terminals.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.
NOTICE
REVERSE POLARITY
nCheck cable polarity at the Xantrex Battery before making
the final DC connection. Positive must be connected to
positive; negative must be connected to negative.
nReversing the positive and negative battery cables will
blow a fuse in the Xantrex Battery and void your warranty.
Failure to follow these instructions can result in equipment
damage.
To secure the battery cable to the battery terminal using
the Rebling connector:
1. Make sure the battery is turned off. See Power Button on
page 21 for instructions on how to operate the Power push
