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.
