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.  

 

 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.
