• The Canadian Electrical Code (CEC)
• The U.S. Code of Federal Regulations (CFRs)
• Canadian Standards Association/CSA Group (CSA) and the RV Industry Association (RVIA) standards and codes for installations in RVs
• The American Boat and Yacht Council (ABYC) standards and US Coast Guard Regulations (33CFR183, Sub Part I) for Marine installations in the U.S.

It is the installer’s responsibility to ensure that all applicable installation requirements are met.

Pre-Installation Checklist

This section provides a list of pre-installation information about where to install the battery and what protective devices are needed. For your convenience, the checklist is divided into these main points:

Checking the Battery

Check the battery, included hardware, box and the battery cables (if included) for visible damage including cracks, dents, chips, and deformations. Ensure that the battery including its components are labeled. Check Materials.
Figure 3 Inspecting the battery

IMPORTANT : Contact Xantrex Technical Support immediately if you see visible damages to the battery or its cables (if included) at +1-800-670-0707,

Choosing a Location for the Battery

WARNING
FIRE AND EXPLOSION HAZARDS

• Do not install the Xantex Battery in compartments containing flammable materials, or in locations that require ignition-protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other connections between components of the fuel system. This equipment contains components that tend to produce arcs or sparks.
• Do not install the Xantex Battery in a zero-clearance compartment. Overheating may result.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Select a location for the battery that is stable, clean, cool, dry, and well ventilated.

• Maintain an ideal operating ambient temperature range of 59 to 77°F (15 to 25°C).
  Temperatures below this range can reduce system performance. Temperatures above this range can reduce battery cell life and reduce system performance.

• Having a nearby heat source can cause premature wear on the cells inside and earlier disconnects during charge and discharge scenarios where the battery produces some heat internally.

• Having a cooling source pointed at the battery can reduce ideal charging scenarios where the battery should ideally be warmer.
  

Map out the location of your batteries with a simple wire diagram for preplanning 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.

• Include all the components on your wire diagram, specifically DC protection devices and major connection points.
• Also 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.

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 Xantex Battery:

1. Select an appropriate mounting location inside your vehicle or vessel.

2. Mount the battery upright (with either the top or side labels pointing up).
   a. On a horizontal surface such as the floor (ideal)
   b. On a battery rack or shelf

3. 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 regulations, refer to ANSI-RVIA LV standard clause 2-3.
   Figure 4 Approved Orientations
   

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

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 :

• A 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.
• As 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.

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:

• (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.
• (B) DC disconnect devices are binary switches that are either open (OFF) or closed (ON) to stop or allow DC current to flow, respectively.
• (C) DC circuit breakers or simply DC breakers are arcreducing electromechanical switches that trip (open fast) with overcurrent and are reset (closed) manually.
  See Figure 7 below.
  

IMPORTANT:

• The battery protection device should be installed inline with the positive cable of the battery.
• Ideally the protection device should be installed as close as practicably possible to the positive terminals of the battery.
• 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.
  Figure 6 DC fuse and DC disconnect
  
  Figure 7 DC breaker
  

Connecting the Battery Cables

WARNING
FIRE HAZARD
Use only stranded, copper wire rated minimum 75 °C (105 °C for marine installations). Make sure all DC connections are tight to a torque of 85–95 in-lb (10–11 Nm) of force. Loose connections will overheat. Too much torque may crack the battery case.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

NOTICE
REVERSE POLARITY

• Check cable polarity at the Xantex Battery before making the final DC connection. Positive must be connected to positive; negative must be connected to negative.
• Reversing the positive and negative battery cables will blow a fuse in the Xantex Battery and void your warranty.

Failure to follow these instructions can result in equipment damage.

To secure the battery cable to the battery terminal:

1. Connect the terminal hardware in the order shown below.
2. Pre-check the M8 bolt thread to see if the bolt is long enough to accommodate all the terminal hardware including the cable ring lug.
3. Also, check that the M8 bolt does not reach the bottom of the battery terminal prematurely causing the lug assembly to be loose and not fully seat.
4. Secure the cable ring lug assembly to the terminal using the torque requirement above.

Parallel Installation

This section provides instructions for installing two to four batteries in parallel to increase power capacity for robust applications in your RV, truck, or vessel. This sections contains the following topics:

Parallel Installation Steps

IMPORTANT :

• Batteries must be of the same make, model, and age for all batteries connected in parallel.
• Before connecting batteries together, verify independently using a multimeter that each battery is charged to 100% SoC. The open terminal voltage should be within 0.05VDC of each other at the point of connection. This procedure helps ensure that there is minimal current flow and sparking between batteries.
  Note that you can also use the Xantrex App to provide a reading of SoC information. Nevertheless, a voltage measurement using a multimeter must be taken to ensure there is as little voltage between the terminals as possible.

NOTICE
EQUIPMENT DAMAGE
Do not connect batteries in series.
Failure to follow these instructions can result in equipment damage.

This is for illustration purposes only.
NOTE : Keep the cables between batteries and ground cables the same lengths for optimal performance and to ensure equal discharging and charging.

BMS Operations

Power Button

The Xantrex Lithium-ion Battery has a Power button on the unit that turns the state of the battery to either ON or OFF.

Keep the battery ON after successfully mounting and integrating it into a power system except when storing, moving, or shipping it.
NOTE : All below temperatures are based upon measured cell temperatures, not upon ambient temperatures.

Cold Ambient Temperature Operation
The Xantex Battery can operate down to 32 °F (0 °C) while recharging the battery and –4 °F (–20 °C) while discharging. There is no internal heating device inside the battery.
During cold temperature discharge, if the internal cell temperature is below –4 °F (–20 °C) then the BMS will disconnect the cells from the terminals until the internal temperature has risen above 5 °F (–15 °C). This will prevent damage to the cells.
NOTE : Discharging and recharging the battery will produce a limited amount of heat inside the battery but will not be enough to sustain a significant temperature rise in a very cold climate. Consider an external heat source, if you will be operating the battery in a cold climate environment.

Hot Ambient Temperature Operation
The Xantex Battery can operate up to 140 °F (60 °C) while recharging or discharging the battery.
During hot temperature operation, if the internal cell temperature reaches above the high operational range, the BMS will disconnect the cells from the terminals until the internal temperature has dropped 9 °F or about 5 °C below the cutoff point. This prevents damage to the cells and the over cycling of the BMS.
NOTE : Discharging and recharging the battery will produce a limited amount of heat inside the battery. Be aware that in high ambient temperature environments, repeated disconnections are likely, especially if the battery is under high loads or recharge current.
