4. Mount and install the DC wiring components including the battery disconnect switch
(if applicable), fuseholders, and the busbars. Their relative locations are shown in the
system diagram. The battery disconnect switch and the fuseholder for the main
battery fuse should be located as close to the BMS positive terminal as possible. If
applicable, install the fuseholder for the DC load branch fuse on the positive cable
close to the positive DC busbar.
5. Mount and install the second alternator using the tools and instructions provided in
the alternator kit. Follow the steps below as a guide but refer to the manufacturer's
instructions for complete detail.
a. Install the second alternator using the mounting bracket and pulley provided in
the alternator kit.
b. Ensure the alternator chassis is securely fastened to the vehicle metal chassis.
c. Use a straight edge or laser alignment tool to ensure pulleys are within 0.5
degrees of alignment.
d. Check all pulley grooves to ensure they are clean and undamaged. Check the
belt to make sure there are no visible cracks, splits, or defects before installing
it.
e. Install the belt. Ensure the belt is properly seated in the pulley grooves.
f. Check the belt tension between the engine and second alternator according to
the manufacturer's recommendations. Adjust accordingly using the provided
tensioner and a tension gauge. Under or over-tensioned belt will cause belt
slippage and premature belt failure. It can also result in overheating of the
alternator leading to equipment damage.

5.
g. Check that the Balmar Regulator has the "LFP" sticker before mounting. Contact
Xantrex if the "LFP" sticker is missing.
h. Mount the Balmar Regulator.
i. Follow the second alternator manufacturer's wiring instructions and use the
wiring harness in the alternator kit to make the connections between the second
alternator and the Balmar Regulator.
j. Make sure the alternator temperature sensor in the wiring harness is installed
on the second alternator's chassis and connected to the correct pins on the
Balmar Regulator to prevent equipment damage and fire.
k. Make DC cable connections at the alternator. Refer to "DC Cable and Fuse
Requirements" for conductor sizing. Use a separate cable for alternator
negative return to the battery. Ensure all electrical connections are secured. To
protect from dust and water, install a skid plate (not provided but
recommended).
6. Read "DC Cable and Fuse Requirements". Then, make the DC cable connections
between all system devices by following the "System Diagram for Power Connection".
Observe correct polarity.
7. Install the required DC fuses on to their respective fuseholders.
8. If applicable, install a venting tube (rubber tubing) to the pressure balancing valve on
the battery and secure it with a clamp.
9. Make AC wiring connections to the Freedom XC PRO Inverter/Charger according to
the "System Diagram for Power Connection". Follow the Freedom XC PRO
Inverter/Charger installation guide (document number: 975-0099-01-01) for AC wire
sizing instructions.
a. Wire the Freedom XC PRO Inverter/Charger AC OUTPUT to your AC load
panel.
b. Ensure that all upstream and downstream surge protector and AC circuit
breakers and downstream GFCIs are properly installed. Refer to the Freedom
XC PRO Inverter/Charger installation guide for breaker sizes.

Installation
WARNING
HAZARD OF ELECTRIC SHOCK, FIRE, OR PERSONAL INJURY
Read the system installation guide and associated product manuals prior to installation.
Failure to follow these instructions can result in death or serious injury.
1. Prior to installation, identify and isolate all energy sources from the system. De-
energize the system by:
a. removing AC power
b. turning off vehicle ignition
c. turning off the BMS
Keep the system de-energed throughout the installation process.
Follow all necessary safety precautions, use personal protective equipment (PPE) and
perform lock-out, tag-out (LOTO).
2. Plan the mounting locations for all the devices and wiring components prior to wiring.
Follow the mounting instructions for each device, verify the weight-bearing capacity of
each mounting location and orientation, and ensure sufficient clearance for proper air
ventilation.
3. Mount and install the system devices before making cable or wiring connections.
Secure heavy objects such as the inverter and the battery by bolting/strapping them to
the floor.
10. Make the system communication connections between all system devices using the
provided system wiring harness (881-0042-12). Use the labels on the wiring harness
as a guide and follow the "System Diagram for Communication Connection". Follow
the vehicle manufacturer's instructions when wiring to the vehicle's ignition circuit.
11. End devices in the CANbus network must both be terminated with a 120Ω resistor.
12. Ensure the installation complies with regional, national, and local electrical codes.
13. Make sure all DC and AC connections are secure. Install and put on all necessary
safeguard and covers. Make sure there are no exposed conductors. Remove LOTO.
14. Perform the end-of-line functional check (document number: 976-0361-01-01). Make
sure that the Battery Type is set to LFP.
