Troubleshooting
The CPS480PAU inverter contains a fuse inside in the cigar plug (see
Figure 1) to protect the unit against overloading. If the inverter draws
more than 150 watts, the internal fuse may open to protect the inverter,
vehicle battery, and the connected equipment. To replace the fuse, please
follow the instructions below:
1. Unplug the inverter from the power source.
2. Remove the contact retainer from the 12V DC adapter.
3. Replace the 15 amp fuse.
4. Reassemble the fuse, contact pin, and contact screw carefully.
5. Ensure all pieces shown in Figure 1 are installed in the correct
sequence.

This equipment has been tested and found to comply with the limits for a Class B Digital Device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures: (1) Reorient or relocate the receiving antenna. (2) Increase the separation between the
equipment and receiver. (3) Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected. (4) Consult the dealer or an experienced radio/TV technician for
help. Any special accessories needed for compliance must be specified in the instruction.
CAUTION: A shielded-type power cord is required in order to meet FCC emission limits and
also to prevent interference to the nearby radio and television reception. It is essential that only the
supplied power cord be used. Use only shielded cables to connect I/O devices to this equipment.
