POWER DISTRIBUTION ASSEMBLY
The Power Distribution Assembly, inside the CPI, has three circuit breakers to protect
the internal dyno circuits, the main dyno circuit breaker and two blower circuit
breakers.

REAKER
The main dyno circuit breaker is rated for 240VAC at 30A and all of the power into the
dyno passes through this breaker. In the event of a major overload or failure this
breaker will trip. This breaker also provides the main disconnect for the dyno. When
the handle is in the up position the dyno is connected to the incoming power. When
the handle is in the down position all power into the dyno is turned off. Refer to Figure
4-2 on page 4-9.
Even if this breaker is turned off there is still the potential for lethal
voltages to be present in the CPI. Always disconnect the main power plug
before removing the covers.

REAKERS
The high pressure blower (blower) circuits are protected by the two 15A breakers. In
the event of a motor failure or other failure with the blowers these breakers could trip.
The white button pops out to indicate the circuit has tripped. Pressing in the white
button will reset the breaker. The top breaker protects the right blower circuit (right
side of dyno as you are sitting on the bike) and the bottom breaker protects the left
blower circuit. These breakers do not provide a manual disconnect.
