SECTION 3: ELECTRICAL AND CHEMICAL SAFETY
Electrical safety is foremost on the FunRunner,
since voltage levels present can cause severe
burns, shock, or death.
High voltage electric shock can cause muscle
contractions. A current of only 10mA can cause
muscles to contract. Hands that are exposed to
enough electrical current clinch
tight and cannot
release their grip.
Even a small amount of current can cause body
tissue damage. Damage to tissue is caused by
heat generated from current flow. When the
heat passes a point where it can be dissipated,
the body tissue is burned.
Fibrillation, the disruption of the body’s normal
heartbeat, can be caused by electrical shock.
The current must pass through the body, such
as with a hand-to-hand connection, in order for
fibrillation to occur.
Arcing occurs when electricity is discharged
across a circuit gap. The heat at the ends of an
arc can be four times the surface temperature of
the sun. Severe burns can be caused when a
person is near or in contact with an arc.
An arc can cause an electric blast. The blast is
the expansion of the air and molten metal,
usually copper, from the rapid heating taking
place.
High Voltage Safety Procedures
The FunRunner’s high voltage and low voltage
systems are isolated from chassis ground under
normal circumstances. You must touch both a
positive and negative point in the circuit in order
to receive an electric shock. You should never
ground any wire on the FunRunner to the
chassis. Doing so could put the operator and
any service personnel in danger.
The FunRunner is equipped with a master
disconnect switch. See Figure 3-1.
Figure 3-1:
The master switch is a safety device that allows
the battery pack voltage to be removed from the
controller. The switch is to be used to
disconnect the battery from the controller before
starting any repairs to the high voltage portion of
the vehicle.
The master switch is located behind the seat.
See Figure 3-2. It can be turned off by sliding
the seat forward, reaching behind the seat and
twisting the red knob. The knob can be pulled
off of the switch when in the off position to
ensure that it is not inadvertently turned back on.
Figure 3-2:
The FunRunner has high voltage in the
propulsion, charging and ignition switch circuits.
