CAUTION!
Ensure that fuse or circuit-breaker protection is provided at the
power source. If you must cut the processor’s 10-foot power
cable shorter, be sure to keep the external fuse intact. If the
power cable must be longer than 10 feet, use a heavier gauge
wire for those applications, and be sure to use an external fuse.
