lUse DC cables with a higher insulation temperature rating (105°C) if possible.

However, a higher insulation temperature rating does not mean the conductor size

can be reduced due to the temperature ratings of the terminal connections. Always

use a qualified installer to ensure conductor sizing complies with regional, national,

and local electrical codes.

lThe DC cables must be UL marked and certified.

lLonger cables may cause excessive voltage drop and affect system performance.

Keep cable length as short as practically possible.

lUse twin wires [pos(+) and neg(-) DC cables] for all DC connections. Do not use the

vehicle chassis in place of the DC negative connection. The system requires reliable

DC return paths.

lThe battery system must be used with a Xantrex-approved fuse (see Table 1 for a list

of approved fuse options). The main battery fuse and all other fuses in the system

must be installed on the positive (ungrounded) conductor as close to their power

sources as possible. Distance restrictions may apply according to applicable codes.

lThe DC load branch, if installed, must be properly fused. The total DC load branch

should not exceed 30A to avoid overheating the main DC cables and blowing the

main battery fuse. It is the installer's responsibility to ensure the voltage, current and

interrupt ratings of the DC load branch fuse are adequate to protect the cables and

downstream loads according to applicable codes.

lUse Xantrex-approved busbars (Blue Sea, 2104) to make the DC interconnections to

ensure sufficient current-carrying capacity. You must follow the connection order at

the busbar terminal studs (DC load - alternator - BMS - Freedom SW) as shown in the

system diagram for optimal heat transfer. Use the same connection order for both

positive and negative busbars.

lEnsure there is sufficient space between the DC positive and negative busbars and

fuse holders.

lAll terminals must be tightened according to the manufacturer’s torque specifications.

lCertain codes require a service disconnect such as a battery disconnect switch. In

this case, you must select a battery disconnect switch with a continuous current rating

of no less than 450A and a voltage rating of no less than 12V.

lEnsure all system devices are properly and securely grounded to the vehicle chassis

using the correct wire sizes.

lInstall terminal covers and make sure there are no exposed conductors.
