Maintenance

3. Connect the positive battery cable from the inverter/charger to the

positive terminal on the battery; then the negative to the negative with

the last connection made at the Xantrex HD terminal to prevent

sparks. You may hear an audible “pop” and see a spark when you

make the last connection.

4. Tighten to a torque of 14.5 ft-lbs (+/-10%).

5. Check that the inverter is operating by enabling it from the toggle

switch as explained in “Using the toggle switch” on page 2–9.

Replacing the fuse

The inverter/charger over-current protection fuse, shown in Figure 1-1,

protects the unit from internal failure or reverse polarity when connecting

it to the battery. If it blows for any reason, replace it with only the fuse

types listed below.

• Littelfuse Mega® Fast Blow, 250 A, 32 V; part number 298250

• Bussmann® 250 A 48 V; part number AMG-250

To replace the fuse:

1. Lift the fuse cover off as shown in Figure 3-2.

2. Remove the spent fuse and install the new fuse.

Be sure to use a lock washer when replacing the nuts. Tighten to a

torque of 4-5.5 ft-lb (5.5-7.5 Nm).

WARNING: Explosion or Fire

Do not complete the next step if flammable fumes are

present. Explosion or fire may result. Thoroughly ventilate

the battery compartment before making this connection.

WARNING: Correct fuse type

To reduce the risk of fire and electrical hazards, replace the fuse

with a fuse of the same type and rating.

Using the wrong fuse type can damage the unit and void your

warranty.
