Understanding Fault Codes

5–2
Some inexpensive stereo systems may emit a buzzing noise from their
loudspeakers when operated from the XM Series Inverter. This occurs
because the power supply in the audio system does not adequately filter
the modified sine wave produced by the inverter. The only solution is to
use a sound system that has a higher quality power supply.
When the XM Series Inverter is operating, it can interfere with television
reception on some channels. If interference occurs, try the following:
1. Make sure that the chassis ground stud on the XM Series Inverter is
solidly connected to the ground system of your vehicle or home.
2. Make sure that the television antenna provides an adequate ("snow-
free") signal, and that you are using good quality cable between the
antenna and the television.
3. Keep the cables between the battery and the XM Series Inverter as
short as possible, and twist them together with two to three twists per
foot. (This minimizes radiated interference from the cables.)
4. Move the television as far away from the XM Series Inverter as
possible.
5. Do not operate high power loads with the XM Series Inverter while
the television is on.
This table explains the fault codes that appear on the three-digit display.
These codes alert you to the following conditions:
• DC input under-voltage
• DC input over-voltage
• AC overload conditions
• Short circuit
• Over-temperature.
