accidental short circuits and overload conditions. The
output is isolated from chassis and earth ground, permitting
full flexibility of connections. When desired, the positive
(+) or negative (-) polarity outputs may be strapped to
ground, allowing use with negative-ground and
positive-ground automotive equipment.
